glennrub	002f7d1ad7	nrf: Replace custom-HAL with nrfx-HAL Summarized this squashed PR replaces the hal/ folder in the port. This has been replaced the official HAL layer from Nordic Semiconductor; https://github.com/NordicSemiconductor/nrfx. A Git submodule has been added under lib/nrfx, for the nrfx dependency. The drivers / modules has been updated to use this new HAL layer; nrfx at v1.0.0. Also, header files and system files for nrf51/nrf52x chip variants has been deleted from the device/ folder, only keeping back the startup files written in C. All other files are now fetched from nrfx. 3 new header files in the ports/nrf/ folder has been added to configure nrfx (nrfx_config.h), logging (nrfx_log.h) and glue nrfx together with the drivers and modules from micropython (nrfx_glue.h). The PR has been a joint effort from @aykevl (Ayke van Laethem) and @glennrub. For reference, the commit log will be kept to get an overview of the changes done: * ports/nrf: Initial commit for moving hal to Nordic Semiconductor BSD-3 licensed nrfx-hal. * ports/nrf: Adding nrfx, Nordic Semiconductor BSD-3 hal layer, as git submodule checked out at lib/nrfx. * ports/nrf/modules/machine/uart: Fixing bug which set hwfc to parity excluded, always resulting in no flow control, hence corrupted output. Also adding an extra loop on uart_tx_char to prevent any tx when any ongoing tx is in progress. * ports/nrf/i2c: Moving I2C over to nrfx driver. * ports/nrf/modules/machine/i2c: Alignment. Renaming print function param 'o' to 'self_in' * ports/nrf/spi: Updating SPI machine module to use nrfx drivers. * ports/nrf: Renaming modules/machine/rtc.c/.h to rtcounter.c/.h to not confuse the peripheral with Real-Time Clock: * ports/nrf: Updating various files after renaming machine module RTC to RTCounter. * ports/nrf: Renaming RTC to RTCounter in modmachine globals dict table. Also updating object type name to reflect new module name. * ports/nrf: Fixing leftovers after renaming rtc to rtcounter. * ports/nrf: Early untested adoption of nrfx_rtc in RTCounter. Untested. * nrf/modules/machine/i2c: Improve keyword argument handling * ports/nrf/modules/temp: Updating Temp machine module to use nrfx defined hal nrf_temp.h. Moving logic of BLE stack awareness to machine module. * ports/nrf/boards/pca10040: Enable machine Temp module. * nrf/modules/machine/rtcounter: Remove magic constants. * ports/nrf: Adding base support for nrfx module logging. Adding option to disable logging of UART as it might log its own setup over UART while the peripheral is not yet set up. Logging of UART could make sense if other transport of log is used. * ports/nrf: updating nrfx_log.h with more correct parenthisis on macro grouping. * ports/nrf: Updating nrfx logging with configuration to disable logging of UART module. The pattern can be used to turn off other modules as well. However, for now UART is the only module locking itself by logging before the peripheral is configured. Logging is turned off by default, can be enabled in nrfx_config.h by setting NRFX_LOG_ENABLED=1. * ports/nrf/modules/random: Updating modrandom to use nrfx hal for rng. Not using nrfx-driver for this peripheral as its blocking mode would do the trick on RNG. Moving softdevice aware code from legacy hal to modrandom.c. * nrf: Enable Peripheral Resource Sharing. This enables TWI and SPI to be enabled at the same time. * nrf/Makefile: Define MCU sub variant (e.g. NRF51822/NRF51422) * nrf: Port TIMER peripheral to nrfx HAL. * nrf/modules/machine/uart: Optimize UART module For a nRF51, this results in a size reduction of: .text: -68 bytes .data: -56 bytes * nrf/modules/machine/uart: Don't use magic index numbers. * nrf/modules/machine/uart: Fix off-by-one error. For nrf51: .text: -40 bytes * nrf/modules/machine/rtcounter: Update for nrfx HAL. * nrf/modules/machine/i2c: Reduce RAM consumption. Reductions for the nrf51: flash: -108 bytes RAM: -72 bytes * nrf/mpconfigport: Avoid unnecessary root pointers. This saves 92 bytes of RAM. * nrf: Support SoftDevice with nrfx HAL. * nrf: Add NVMC peripheral (microbitfs) support. There is no support yet for a SoftDevice. It also fixes a potentially serious bug in start_index generation. * nrf/modules/machine/spi: Optimize SPI peripheral. nrf51: text: -340 bytes data: -72 bytes nrf52: text: -352 bytes data: -108 bytes * nrf/modules/random: Forgot to commit header file. * nrf: Make nrfx_config.h universal for all boards. * nrf: Use SoftDevice API for flash access when built for SD * nrf/drivers/bluetooth: Remove legacy HAL driver includes. These were not used anymore so can be removed. * ports/nrf/microbit: Port microbit targets to nrfx HAL Initial port of microbit modules to use nrfx HAL layer. Tested display/image and modmusic on micro:bit to verify that softpwm and ticker for nrf51 is working as expected. Changing IRQ priority on timer to priority 2, as 1 might collide if used side by side of SD110 BLE stack. The patch reserves Timer1 peripheral compile time. This is not ideal and should be resolved in seperate task. * nrf/boards/microbit: Remove custom nrfx_config.h from microbit target, adding disablement of timer1 if softpwm is enabled. * nrf/adc: Update ADC module to use nrfx * nrf/modules/machine/pwm: Updating machine PWM module to use nrfx HAL driver. examples/nrf52_pwm.py and examples/nrf52_servo.py tested on pca10040. * nrf: Removing hal folder and boards nrf5x_hal_conf.h headers. * nrf/nrfx_glue: Adding direct NVIC access for S110 BLE stack If SoftDevice s110 has not yet been initialized, the IRQ will not be forwarded to the application using the sd_nvic* function calls. Hence, direct access to cmsi nvic functions are used instead if SoftDevice is not enabled. * nrf/drivers/ticker: Setting IRQ priority 3 on Timer1 SoftDevice fails to initilize if Timer1 has been configured to priority level 2 before enabling the SD. The timer is set to priority 1, higher than BLE stack in order to provide better quality of music rendering when used with the music module. This might be too high, time will show. * nrf/examples: Updating ubluepy_temp after moving RTCounter to nrfx. * nrf: delete duplicate files from device folder which can be located in nrfx/mdk. * nrf/Makefile: Fetch system files from nrfx. Testing on each device sub-variant to figure out which system file to use. Reason for this is that nrf52.c is actually defining nrf52832. Removing NRF_DEFINES parameter setting the device in use into the same sub-variant test, as NRF52 is unique to nrf52832 when using nrfx. Without this exclusion of -DNRF52 in compilation for nrf52840, the device will be interpreted as a nrf52, hence nrf52832. Also, changing name on variable SRC_NRF_HAL to SRC_NRFX_HAL to explicitly tell the origin of the file. * nrf: Updating device #ifdefs to be more open to non-nrf51 targets. * nrf/modules/machine/uart: Removing second instance of UART for nrf52840 as it only has one non-DMA variant. * nrf/device: Removing system files as these are now used from nrfx/mdk * nrf: Moving startup files in device one level up as there is no need for deep hierarchy. * nrf: Use NRF52_SERIES defined in nrfx/mdk/nrf.h as define value when testing for both nrf52(832) and nrf52840 variants. * nrf/modules/machine/uart: Enable UART RX by default Enable rx by default after intiialization of the peripheral. Else, the nrfx driver will re-enable rx for each byte read on uart REPL, clearing the EVENT_RXDRDY before second byte, which again will make second byte get lost and read will get stuck. This happens if the bytes are transmitted nrf(51) while still processing the previous byte. Not seen on nrf52, but should also become an issue at higher speeds. This patch sets rx to always be enabled. Hence, not clearing the event between read bytes, and it will be able to detect next byte recieved upon finishing the first. * nrf/modules/machine/timer: Fixing defines excluding Timer1 if ticker/softpwm is used. * nrf: Switching import form mpconfigboard.h to mpconfigport.h in nrfx_config.h as mpconfigboard.h might define default values for defines not set by board specific header. * nrf/modules/machine/i2c: nrfx integration fixes Increasing speed to 400K. Returning Address NACK's as MP error code; MP_ENODEV. Returning MP_ETIMEOUT on all other error codes from TWI nrfx driver except the ANACK. Enabling and disabling the TWI peripheral before and after each transaction. * nrf/examples: Updating ssd1306_mod.py to split framebuffer transfer into multiple chunks * nrf/modules/machine/i2c: Return MP_EIO error if Data NACK occurs. * nrf: Addressing review comments. * nrf: Updating git submodule and users to nrfx v1.0.0. * nrf/modules/machine/adc: Update adc module to follow v1.0.0 nrfx API. * nrf/modules/machine/spi: Implement init and deinit functions Extending SPI objects with a config member such that configuration can be kept between new() and init(). Moving initialization done in new() to common init function shared between the module functions. If SPI is already configured, the SPI peripheral will be uninitialized before initalized again. Adding logic to handle initialization of polarity and phase. As well, updating default speed to 1M from 500K. * nrf/modules/machine: Removing unused nrfx includes in machine module header files	7 years ago
Daniel Tralamazza	e22b943508	nrf: Add new port to Nordic nRF5x MCUs. This commit is a combination of about 802 commits from the initial stages of development of this port, up to and including the point where the code was moved to the ports/nrf directory. The following is a digest of the original commits in their original order (most recent listed first), grouped where possible by author. The list is here to give credit for the work and provide some level of traceability and accountability. For the full history of development please consult the following repository: https://github.com/tralamazza/micropython Unless otherwise explicitly state in a sub-directory or file, all code is MIT licensed and the relevant copyright holders are listed in the comment-header of each file. Glenn Ruben Bakke <glennbakke@gmail.com> ports/nrf: Moving nrf51/52 port to new ports directory nrf: Aligning with upstream the use of nlr_raise(mp_obj_new_exception_msg(&mp_type_ValueError, ...) Glenn Ruben Bakke <glennbakke@gmail.com> nrf/modules/random: Backport of microbit random number generator module Backport of micro:bit random module. Plugged into the port as a general random module for all nrf51/nrf52 targets. Works both with and without Bluetooth LE stack enabled. Behavioral change: seed() method has been removed, as the use of RNG peripheral generates true random sequences and not pseudo-random sequences. Glenn Ruben Bakke <glennbakke@gmail.com> nrf/hal/rng: Adding HAL driver for accessing RNG peripheral The driver also takes care of calling the Bluetooth LE stack for random values if the stack is enabled. The reason for this is that the Bluetooth LE stack take ownership of the NRF_RNG when enabled. Tolerate to enable/disable on the fly, and will choose to use direct access to the peripheral if Bluetooth LE stack is disabled or not compiled in at all. Driver has been included in the top Makefile, and will not be compiled in unless nrf51_hal_conf.h/nrf52_hal_conf.h defines HAL_RNG_MODULE_ENABLED (1). Glenn Ruben Bakke <glennbakke@gmail.com> nrf/boards: Adding Arduino Primo board support (#88) * nrf: Adding Arduino Primo board support * nrf: Adding arduino_primo to target boards table in readme.md * nrf/boards: Activating pyb.LED module for arduino_primo board. * nrf/boards: Removing define not needed for arduino_primo Updating arduino_primo board mpconfigboard.h. Removing a define that was wrongly named. Instead of renaming it, it was removed as it was never used. Glenn Ruben Bakke <glennbakke@gmail.com> nrf: Add support for floating point on nrf52 targets. Duplicating pattern for detecting location of libm, libc and libgcc from teensy port. Activating MICROPY_FLOAT_IMPL (FLOAT) for nrf52 targets and adding libs into the compile. For nrf51 targets it is still set to NONE as code grows to much (about 30k). Some numbers on flash use if MICROPY_FLOAT_IMPL is set to MICROPY_FLOAT_IMPL_FLOAT and math libraries are enabled (lgcc, lc, lm). nrf51: ====== without float support: text data bss dec hex filename 144088 260 30020 174368 2a920 build-pca10028/firmware.elf with float support: text data bss dec hex filename 176228 1336 30020 207584 32ae0 build-pca10028/firmware.elf nrf52: ====== without float support: text data bss dec hex filename 142040 356 36236 178632 2b9c8 build-pca10040/firmware.elf with float support: text data bss dec hex filename 165068 1436 36236 202740 317f4 build-pca10040/firmware.elf Daniel Tralamazza <daniel@tralamazza.com> nrf: add a note for running the nrfjprog tool on Linux, and touch up the make sd comment nrf: clean compiler warnings Glenn Ruben Bakke <glennbakke@gmail.com> nrf/drivers/bluetooth: Speedup Bluetooth LE REPL.

Also adding some example usage in the comment in top of the file for both SPI and I2C variant. nrf5/hal/gpio: Updating toggle inline function to work correctly, currently only used by LED module. nrf5/examples: Renaming servo.py to nrf52_servo.py as it is only implemented machine.PWM for nrf52. nrf5/freeze: Adding generic example to freeze. Hello world with board name as parameter. nrf5/examples: Moving nrf52 specific HW example from freeze to examples to replace test.py with a more generic example. nrf5: Update pyb module, and led module to only be compiled in if MICROPY_HW_HAS_LED is set to 1. nrf5/boards: Updating boards with correct LED count. Also adding new flag, MICROPY_HW_HAS_LED, to select whether the board has LED's at all. If not, this will unselect LED module from being compiled in. nrf5/boards: Updating pca10040 board header to set the LED count. nrf5: Generalize script setting LED(1) on to be applied only when there are leds present on the board. nrf5: Updating mpconfigport.h to set default values for MICROPY_HW_LED_COUNT (0) and MICROPY_HW_LED_PULLUP (0). nrf5/boards/feather52: Update s132 target makefile with dfu-gen and dfu-flash.

Also removing some commented out arguments to remove some confusion in the argument list. Done for both play() and pitch(). nrf5/modules/music: Correct parameter checking of pin argument to deside whether to use MUSIC_PIN define or throw an error. If MUSIC_PIN define is configured the pin argument to music module play() can be elided. nrf5/modules/machine: Update timer init to set default IRQ priority before initializing Timer instance. nrf5/hal/timer: Update timer hal to use value provided in init to configure the irq_priority. nrf5/modules/machine: Reserving timer0 instance for bluetooth if compiled in. Leaving timer1 and timer2 for application. Note that music module soft-pwm will also occupy timer1 if enabled. nrf5/modules/machine: Updating timer module to use new hal. Adding new parameters to the init to set period, mode and callback. nrf5/hal/timer: Implementing hal_timer to 1us prescaler. Multiplier inside to get to millisecond resolution. Callback must be registered before starting a timer. nrf5: Makefile cleanup. Removing duplicate include and unused netutils.c used by BLE 6lowpan network which has been removed for now. nrf5/modules/machine: Indention fix in uart module. nrf5/modules/machine: Removing unused code from uart module. nrf5/hal/rtc: Updating hal driver to calculate prescaler a bit more verbose.

Matt Trentini <matt.trentini@gmail.com> Adding a README for the nRF5 port Glenn Ruben Bakke <glennbakke@gmail.com> nrf5/examples: Updating documentation in SDCard module example. Correcting typo and adding SD card wireing documentation for direct SPI connection. nrf5/modules/pin: Adding on() and off() methods to Pin object to be forward compatible with upstream master. Legacy high() and low() methods are kept. nrf5/modules/spi: Remove pyb abstraction from SPI module, as there was a bug in transfer of bytes due to casting errors. The update removes the pyb_spi_obj_t wrapper going directly on the machine_hard_spi_obj_t as base for machine SPI objects. SDCard mounting is also tested. nrf5/drivers/bluetooth: Enable ubluepy central by default if running nrf52/s132 bluetooth stack. Maturity of the module is pretty OK now. nrf5/boards/feather52: Updating pins.csv for the feather52 board. nrf5/boards/feather52: Updating LED pull to low. nrf5/boards/feather52: Update SPI pinout. nrf5/main: Move initializaton of modmusic to the module itself. Upon init of the module, the hardware, pwm and ticker will be started. Could be moved back to main if pwm or ticker should be shared among more modules and have to be initialized more global. nrf5/modules/machine/timer: If timer is used in combination with SOFT_PWM (implicitly use of ticker.c) guard the Timer1 instance from being instantiated trough python timer module. Also disable implementation of the HAL IRQ handler which is for now explicitly implemented in ticker.c for Timer1. nrf5/modules/music: Update ticker and modmusic to share global ticks counter as a volatile variable. Use Timer1 hardware peripheral instead of instance 0. Timer0 is not free if used in combination with a bluetooth stack. Update IRQ priority to levels that are compatible in use with a bluetooth stack for both nrf51 and nrf52. Apply nrf51 PAN fixes for Timer1 instead of original Timer0. nrf5/drivers/bluetooth: Updating bluetooth driver to initialize nrf_nvic_state_t struct during declaration of the global variable instead of explicit memset. nrf5/hal/irq: Adding wrappers for handling nvic calls when Bluetooth LE stack is enabled. nrf5/modules/machine: Updating IRQ levels in SPI with IRQ priorities compatible with Bluetooth stacks. nrf5/device: Remove old startup files in asm, which has now been replaced with c-implementation. nrf5: Update Makefile to add c-implementation of startup scripts instead of the .s files. nrf5/device: Adding startup files in .c to replace current asm versions. nrf5/examples: Tuning Bluetooth LE example controller python script after testing out the example live. Motor speed of 100 was not enought to lift the airplane. Also turning was hard without setting higher angle values. The new values are just guessed values. However, the flying experience was good. nrf5/hal/irq: Adding include of nrf_nvic.h if s132 bluetooth stack is used to resolve IRQ function wrappers on newer bluetooth stacks. nrf5/drivers/ticker: Removing unused code. nrf5/examples: Adding music example. Only working if bluetooth stack is not enabled. nrf5/boards/microbit: Disable music and softPWM as there are some issues with the ticker. nrf5: Adding -fstack-usage flag to gcc CFLAGS to be able to trace stack usage on modules. nrf5/drivers/ticker: Removing LowPriority callback from nrf51 as there is only one SoftwareIRQ free if bluetooth stack is enabled. Also setting new IRQ priority on SlowTicker to 3 instead of 2, to interleave with bluetooth stack if needed. Updating all NVIC calls to use hal_irq.h defined static inlines instead of direct access. nrf5/hal/irq: Adding IRQ wrappers if Bluetooth Stack is present. nrf5: Facilitate option to configure away the modble if needed. Enabled if MICROPY_PY_BLE config is enabled in bluetooth_conf.h. nrf5/boards/microbit: Enable music module by default. However, timer and rtc module has to be disabled. Bluetooth support broken. Optimization needed. nrf5/modules/machine: Quickfix. Update timer object to not allow instanciation of Timer(0) if SOFT_PWM is enabled by board. nrf5/hal/timer: Quickfix. Disable IRQ handler if SOFT_PWM is configured to be enabled. Ticker driver has in current driver a seperate IRQ handler for this timer instance. nrf5/drivers/ticker: Add compile config guard in ticker.c to only include the driver if SOFT_PWM is configured in by board. nrf5/drivers/softpwm: Renaming pwm_init to softpwm_init to not collide on symbol name with pwm_init in nrf52 machine PWM object. nrf5: Add modmusic QSTR definition of notes to qstrdefsport.h. nrf5: Update Makefile to include ticker.c and renamed softpwm. Updating also include paths to include modules/music and drivers/. nrf5: Adding include of modmusic.h in main.c. nrf5: Call microbit_music_init0() if enabled in main.c. nrf5/modules/music: Expose public init function for music module. nrf5/modules/music: Update modmusic to use updated includes. Add extern ticks. Add function which implements initialization of pwm and ticker, register ticker callback, and start the pwm and ticker. This corresponds to microbit port main.cpp init. nrf5/drivers/softpwm: Enable use of ticker in softpwm driver. nrf5/drivers/ticker: Adding ticker.c/.h from microbit port. nrf5/drivers/pwm: Renaming pwm.c/.h to softpwm.c/.h nrf5/drivers/pwm: Expose pwm_init() as public function. nrf5/modules/ubluepy: Making peripheral conn_handle volatile. Upon connection event, the variable is accessed in thread mode. However, the main-loop is blocking on conn_handle != 0xFFFF. If this is not volatile, optimized code will not exit the loop. nrf5/drivers/bluetooth: As callback functions are in most usecases are set to NULL upon last event to get public API function out of blocking mode, these function pointers has to be set as volatile, as they are updated to NULL in interrupt context, but read in blocking main-thread. nrf5/examples: Fixing overlapping function names and variable names inside the object. Also removing some print statements. Tuning max angle from -7/7 to -25/25.

nrf: Replace custom-HAL with nrfx-HAL

Summarized this squashed PR replaces the hal/ folder in the port. This has been replaced the official
HAL layer from Nordic Semiconductor; https://github.com/NordicSemiconductor/nrfx.

A Git submodule has been added under lib/nrfx, for the nrfx dependency.

The drivers / modules has been updated to use this new HAL layer; nrfx at v1.0.0.

Also, header files and system files for nrf51/nrf52x chip variants has been deleted from the device/ folder, only keeping back the startup files written in C. All other files are now fetched from nrfx.

3 new header files in the ports/nrf/ folder has been added to configure nrfx (nrfx_config.h), logging (nrfx_log.h) and glue nrfx together with the drivers and modules from micropython (nrfx_glue.h).

The PR has been a joint effort from @aykevl (Ayke van Laethem) and @glennrub.

For reference, the commit log will be kept to get an overview of the changes done:

* ports/nrf: Initial commit for moving hal to Nordic Semiconductor BSD-3 licensed nrfx-hal.

* ports/nrf: Adding nrfx, Nordic Semiconductor BSD-3 hal layer, as git submodule checked out at lib/nrfx.

* ports/nrf/modules/machine/uart: Fixing bug which set hwfc to parity excluded, always resulting in no flow control, hence corrupted output. Also adding an extra loop on uart_tx_char to prevent any tx when any ongoing tx is in progress.

* ports/nrf/i2c: Moving I2C over to nrfx driver.

* ports/nrf/modules/machine/i2c: Alignment. Renaming print function param 'o' to 'self_in'

* ports/nrf/spi: Updating SPI machine module to use nrfx drivers.

* ports/nrf: Renaming modules/machine/rtc.c/.h to rtcounter.c/.h to not confuse the peripheral with Real-Time Clock:

* ports/nrf: Updating various files after renaming machine module RTC to RTCounter.

* ports/nrf: Renaming RTC to RTCounter in modmachine globals dict table. Also updating object type name to reflect new module name.

* ports/nrf: Fixing leftovers after renaming rtc to rtcounter.

* ports/nrf: Early untested adoption of nrfx_rtc in RTCounter. Untested.

* nrf/modules/machine/i2c: Improve keyword argument handling

* ports/nrf/modules/temp: Updating Temp machine module to use nrfx defined hal nrf_temp.h. Moving logic of BLE stack awareness to machine module.

* ports/nrf/boards/pca10040: Enable machine Temp module.

* nrf/modules/machine/rtcounter: Remove magic constants.

* ports/nrf: Adding base support for nrfx module logging. Adding option to disable logging of UART as it might log its own setup over UART while the peripheral is not yet set up. Logging of UART could make sense if other transport of log is used.

* ports/nrf: updating nrfx_log.h with more correct parenthisis on macro grouping.

* ports/nrf: Updating nrfx logging with configuration to disable logging of UART module. The pattern can be used to turn off other modules as well. However, for now UART is the only module locking itself by logging before the peripheral is configured. Logging is turned off by default, can be enabled in nrfx_config.h by setting NRFX_LOG_ENABLED=1.

* ports/nrf/modules/random: Updating modrandom to use nrfx hal for rng. Not using nrfx-driver for this peripheral as its blocking mode would do the trick on RNG. Moving softdevice aware code from legacy hal to modrandom.c.

* nrf: Enable Peripheral Resource Sharing.

This enables TWI and SPI to be enabled at the same time.

* nrf/Makefile: Define MCU sub variant (e.g. NRF51822/NRF51422)

* nrf: Port TIMER peripheral to nrfx HAL.

* nrf/modules/machine/uart: Optimize UART module

For a nRF51, this results in a size reduction of:
.text: -68 bytes
.data: -56 bytes

* nrf/modules/machine/uart: Don't use magic index numbers.

* nrf/modules/machine/uart: Fix off-by-one error.

For nrf51:
.text: -40 bytes

* nrf/modules/machine/rtcounter: Update for nrfx HAL.

* nrf/modules/machine/i2c: Reduce RAM consumption.

Reductions for the nrf51:
flash: -108 bytes
RAM: -72 bytes

* nrf/mpconfigport: Avoid unnecessary root pointers.

This saves 92 bytes of RAM.

* nrf: Support SoftDevice with nrfx HAL.

* nrf: Add NVMC peripheral (microbitfs) support.

There is no support yet for a SoftDevice.

It also fixes a potentially serious bug in start_index generation.

* nrf/modules/machine/spi: Optimize SPI peripheral.

nrf51:
text: -340 bytes
data: -72 bytes

nrf52:
text: -352 bytes
data: -108 bytes

* nrf/modules/random: Forgot to commit header file.

* nrf: Make nrfx_config.h universal for all boards.

* nrf: Use SoftDevice API for flash access when built for SD

* nrf/drivers/bluetooth: Remove legacy HAL driver includes.

These were not used anymore so can be removed.

* ports/nrf/microbit: Port microbit targets to nrfx HAL

Initial port of microbit modules to use nrfx HAL layer.
Tested display/image and modmusic on micro:bit to verify that
softpwm and ticker for nrf51 is working as expected.

Changing IRQ priority on timer to priority 2, as 1 might collide if
used side by side of SD110 BLE stack.

The patch reserves Timer1 peripheral compile time. This is not ideal
and should be resolved in seperate task.

* nrf/boards/microbit: Remove custom nrfx_config.h from microbit target, adding disablement of timer1 if softpwm is enabled.

* nrf/adc: Update ADC module to use nrfx

* nrf/modules/machine/pwm: Updating machine PWM module to use nrfx HAL driver.

examples/nrf52_pwm.py and examples/nrf52_servo.py tested on pca10040.

* nrf: Removing hal folder and boards nrf5x_hal_conf.h headers.

* nrf/nrfx_glue: Adding direct NVIC access for S110 BLE stack

If SoftDevice s110 has not yet been initialized, the IRQ will not be forwarded to
the application using the sd_nvic* function calls. Hence, direct access to cmsi
nvic functions are used instead if SoftDevice is not enabled.

* nrf/drivers/ticker: Setting IRQ priority 3 on Timer1

SoftDevice fails to initilize if Timer1 has been configured to priority
level 2 before enabling the SD. The timer is set to priority 1, higher than BLE
stack in order to provide better quality of music rendering when used with the
music module. This might be too high, time will show.

* nrf/examples: Updating ubluepy_temp after moving RTCounter to nrfx.

* nrf: delete duplicate files from device folder which can be located in nrfx/mdk.

* nrf/Makefile: Fetch system files from nrfx.

Testing on each device sub-variant to figure out which system file to
use. Reason for this is that nrf52.c is actually defining nrf52832.

Removing NRF_DEFINES parameter setting the device in use into the
same sub-variant test, as NRF52 is unique to nrf52832 when using nrfx.
Without this exclusion of -DNRF52 in compilation for nrf52840, the
device will be interpreted as a nrf52, hence nrf52832.

Also, changing name on variable SRC_NRF_HAL to SRC_NRFX_HAL to
explicitly tell the origin of the file.

* nrf: Updating device #ifdefs to be more open to non-nrf51 targets.

* nrf/modules/machine/uart: Removing second instance of UART for nrf52840 as it only has one non-DMA variant.

* nrf/device: Removing system files as these are now used from nrfx/mdk

* nrf: Moving startup files in device one level up as there is no need for deep hierarchy.

* nrf: Use NRF52_SERIES defined in nrfx/mdk/nrf.h as define value when testing for both nrf52(832) and nrf52840 variants.

* nrf/modules/machine/uart: Enable UART RX by default

Enable rx by default after intiialization of the peripheral.
Else, the nrfx driver will re-enable rx for each byte read
on uart REPL, clearing the EVENT_RXDRDY before second byte,
which again will make second byte get lost and read will get stuck.

This happens if the bytes are transmitted nrf(51) while still
processing the previous byte. Not seen on nrf52, but should
also become an issue at higher speeds.

This patch sets rx to always be enabled. Hence, not clearing the event
between read bytes, and it will be able to detect next byte recieved
upon finishing the first.

* nrf/modules/machine/timer: Fixing defines excluding Timer1 if ticker/softpwm is used.

* nrf: Switching import form mpconfigboard.h to mpconfigport.h in nrfx_config.h as mpconfigboard.h might define default values for defines not set by board specific header.

* nrf/modules/machine/i2c: nrfx integration fixes

Increasing speed to 400K.

Returning Address NACK's as MP error code; MP_ENODEV.

Returning MP_ETIMEOUT on all other error codes from TWI nrfx driver
except the ANACK.

Enabling and disabling the TWI peripheral before and after each transaction.

* nrf/examples: Updating ssd1306_mod.py to split framebuffer transfer into multiple chunks

* nrf/modules/machine/i2c: Return MP_EIO error if Data NACK occurs.

* nrf: Addressing review comments.

* nrf: Updating git submodule and users to nrfx v1.0.0.

* nrf/modules/machine/adc: Update adc module to follow v1.0.0 nrfx API.

* nrf/modules/machine/spi: Implement init and deinit functions

Extending SPI objects with a config member such that
configuration can be kept between new() and init().

Moving initialization done in new() to common init
function shared between the module functions.

If SPI is already configured, the SPI peripheral will
be uninitialized before initalized again.

Adding logic to handle initialization of polarity and
phase. As well, updating default speed to 1M from 500K.

* nrf/modules/machine: Removing unused nrfx includes in machine module header files

nrf: Add new port to Nordic nRF5x MCUs.

This commit is a combination of about 802 commits from the initial stages
of development of this port, up to and including the point where the code
was moved to the ports/nrf directory.  The following is a digest of the
original commits in their original order (most recent listed first),
grouped where possible by author.  The list is here to give credit for the
work and provide some level of traceability and accountability.  For the
full history of development please consult the following repository:

Glenn Ruben Bakke <glennbakke@gmail.com>
    nrf/modules/random: Backport of microbit random number generator module

    Backport of micro:bit random module.
    Plugged into the port as a general random module for all nrf51/nrf52 targets. Works both with and without Bluetooth LE stack enabled.

    Behavioral change: seed() method has been removed, as the use of RNG peripheral generates true random sequences and not pseudo-random sequences.

Glenn Ruben Bakke <glennbakke@gmail.com>
    nrf/hal/rng: Adding HAL driver for accessing RNG peripheral

    The driver also takes care of calling the Bluetooth LE stack for random values if the stack is enabled. The reason for this is that the Bluetooth LE stack take ownership of the NRF_RNG when enabled. Tolerate to enable/disable on the fly, and will choose to use direct access to the peripheral if Bluetooth LE stack is disabled or not compiled in at all.

    Driver has been included in the top Makefile, and will not be compiled in unless nrf51_hal_conf.h/nrf52_hal_conf.h defines HAL_RNG_MODULE_ENABLED (1).

    nrf: Add support for floating point on nrf52 targets.

    Duplicating pattern for detecting location of libm, libc and libgcc
    from teensy port. Activating MICROPY_FLOAT_IMPL (FLOAT) for nrf52 targets
    and adding libs into the compile. For nrf51 targets it is still set to
    NONE as code grows to much (about 30k).

    Some numbers on flash use if MICROPY_FLOAT_IMPL is set to
    MICROPY_FLOAT_IMPL_FLOAT and math libraries are enabled (lgcc, lc, lm).

    Adding a README for the nRF5 port

Glenn Ruben Bakke <glennbakke@gmail.com>
    nrf5/examples: Updating documentation in SDCard module example. Correcting typo and adding SD card wireing documentation for direct SPI connection.
    nrf5/modules/pin: Adding on() and off() methods to Pin object to be forward compatible with upstream master. Legacy high() and low() methods are kept.
    nrf5/modules/spi: Remove pyb abstraction from SPI module, as there was a bug in transfer of bytes due to casting errors. The update removes the pyb_spi_obj_t wrapper going directly on the machine_hard_spi_obj_t as base for machine SPI objects. SDCard mounting is also tested.
    nrf5/drivers/bluetooth: Enable ubluepy central by default if running nrf52/s132 bluetooth stack. Maturity of the module is pretty OK now.

    nrf5/boards/feather52: Updating LED pull to low.
    nrf5/boards/feather52: Update SPI pinout.
    nrf5/main: Move initializaton of modmusic to the module itself. Upon init of the module, the hardware, pwm and ticker will be started. Could be moved back to main if pwm or ticker should be shared among more modules and have to be initialized more global.
    nrf5/modules/machine/timer: If timer is used in combination with SOFT_PWM (implicitly use of ticker.c) guard the Timer1 instance from being instantiated trough python timer module. Also disable implementation of the HAL IRQ handler which is for now explicitly implemented in ticker.c for Timer1.
    nrf5/modules/music: Update ticker and modmusic to share global ticks counter as a volatile variable. Use Timer1 hardware peripheral instead of instance 0. Timer0 is not free if used in combination with a bluetooth stack. Update IRQ priority to levels that are compatible in use with a bluetooth stack for both nrf51 and nrf52. Apply nrf51 PAN fixes for Timer1 instead of original Timer0.
    nrf5/drivers/bluetooth: Updating bluetooth driver to initialize nrf_nvic_state_t struct during declaration of the global variable instead of explicit memset.
    nrf5/hal/irq: Adding wrappers for handling nvic calls when Bluetooth LE stack is enabled.

    nrf5/device: Remove old startup files in asm, which has now been replaced with c-implementation.
    nrf5: Update Makefile to add c-implementation of startup scripts instead of the .s files.
    nrf5/device: Adding startup files in .c to replace current asm versions.
    nrf5/examples: Tuning Bluetooth LE example controller python script after testing out the example live. Motor speed of 100 was not enought to lift the airplane. Also turning was hard without setting higher angle values. The new values are just guessed values. However, the flying experience was good.
    nrf5/hal/irq: Adding include of nrf_nvic.h if s132 bluetooth stack is used to resolve IRQ function wrappers on newer bluetooth stacks.
    nrf5/drivers/ticker: Removing unused code.
    nrf5/examples: Adding music example. Only working if bluetooth stack is not enabled.
    nrf5/boards/microbit: Disable music and softPWM as there are some issues with the ticker.
    nrf5: Adding -fstack-usage flag to gcc CFLAGS to be able to trace stack usage on modules.
    nrf5/drivers/ticker: Removing LowPriority callback from nrf51 as there is only one SoftwareIRQ free if bluetooth stack is enabled. Also setting new IRQ priority on SlowTicker to 3 instead of 2, to interleave with bluetooth stack if needed. Updating all NVIC calls to use hal_irq.h defined static inlines instead of direct access.
    nrf5/hal/irq: Adding IRQ wrappers if Bluetooth Stack is present.
    nrf5: Facilitate option to configure away the modble if needed. Enabled if MICROPY_PY_BLE config is enabled in bluetooth_conf.h.
    nrf5/boards/microbit: Enable music module by default. However, timer and rtc module has to be disabled. Bluetooth support broken. Optimization needed.
    nrf5/modules/machine: Quickfix. Update timer object to not allow instanciation of Timer(0) if SOFT_PWM is enabled by board.
    nrf5/hal/timer: Quickfix. Disable IRQ handler if SOFT_PWM is configured to be enabled. Ticker driver has in current driver a seperate IRQ handler for this timer instance.
    nrf5/drivers/ticker: Add compile config guard in ticker.c to only include the driver if SOFT_PWM is configured in by board.
    nrf5/drivers/softpwm: Renaming pwm_init to softpwm_init to not collide on symbol name with pwm_init in nrf52 machine PWM object.
    nrf5: Add modmusic QSTR definition of notes to qstrdefsport.h.

    nrf5/modules/music: Expose public init function for music module.
    nrf5/modules/music: Update modmusic to use updated includes. Add extern ticks. Add function which implements initialization of pwm and ticker, register ticker callback, and start the pwm and ticker. This corresponds to microbit port main.cpp init.
    nrf5/drivers/softpwm: Enable use of ticker in softpwm driver.
    nrf5/drivers/ticker: Adding ticker.c/.h from microbit port.
    nrf5/drivers/pwm: Renaming pwm.c/.h to softpwm.c/.h
    nrf5/drivers/pwm: Expose pwm_init() as public function.
    nrf5/modules/ubluepy: Making peripheral conn_handle volatile. Upon connection event, the variable is accessed in thread mode. However, the main-loop is blocking on conn_handle != 0xFFFF. If this is not volatile, optimized code will not exit the loop.
    nrf5/drivers/bluetooth: As callback functions are in most usecases are set to NULL upon last event to get public API function out of blocking mode, these function pointers has to be set as volatile, as they are updated to NULL in interrupt context, but read in blocking main-thread.
    nrf5/examples: Fixing overlapping function names and variable names inside the object. Also removing some print statements. Tuning max angle from -7/7 to -25/25.

    Fix up Makefile dependencies

    I also didn't see any real reason for mkrules.mk to exist,
    so I merged the contents into Makefile.

    Now you can do:
    ```
    make BOARD=pca10028 clean
    make BOARD=pca10028 flash
    ```
    and it will work properly.
