Damien George	e8f2db7da3	py/runtime: Zero out fs_user_mount array in mp_init. There's no need to force ports to copy-and-paste this initialisation code. If FSUSERMOUNT is enabled then this zeroing out must be done.	8 years ago
Damien George	e83f140463	py/mpz: Remove unreachable code in mpn_or_neg functions.	8 years ago
Rami Ali	9112b0b62b	tests/extmod: Improve modframebuf test coverage.	8 years ago
Damien George	0f408bc1ff	stmhal: Move PY_SYS_PLATFORM config from board to general config file. It can be overridden by a board if needed.	8 years ago
Rami Ali	8001918a89	stmhal: Add STM32F769DISC board files. With minor changes to adc.c and storage.c to support the F769.	8 years ago
Rami Ali	3dd04dee3e	stmhal/cmsis: Add CMSIS file stm32f769xx.h, V1.1.2.	8 years ago
Rami Ali	e9fbc555fc	stmhal: Add NUCLEO_F767ZI board, with openocd config for stm32f7.	8 years ago
Rami Ali	517f347f6f	stmhal/cmsis: Add CMSIS file stm32f767xx.h, V1.1.2.	8 years ago
Damien George	d9047d3c8a	py/builtinimport: Support importing packages from compiled .mpy files. This patch ensures that __init__.mpy files are imported if their containing directory is imported as a package.	8 years ago
Rami Ali	d22762017e	tests/extmod: Improve moductypes test coverage.	8 years ago
Damien George	a3c61004c2	py/binary: Do zero extension when storing a value larger than word size.	8 years ago
Paul Sokolovsky	aee13ef3f2	tests: Update for required byteorder arg for int.from_bytes()/to_bytes().	8 years ago
Paul Sokolovsky	9d787de2a1	py/objint: from_bytes, to_bytes: Require byteorder arg, require "little". CPython requires byteorder arg, make uPy compatible. As we support only "little", error out on anything else.	8 years ago
Damien George	93ee6603b1	py/asm: Fix x86 and ARM assemblers due to recent code refactoring.	8 years ago
Damien George	155fdc74d5	py/asm: Remove need for dummy_data when doing initial assembler passes. For all but the last pass the assembler only needs to count how much space is needed for the machine code, it doesn't actually need to emit anything. The dummy_data just uses unnecessary RAM and without it the code is not any more complex (and code size does not increase for Thumb and Xtensa archs).	8 years ago
Damien George	e920bab976	py/emitinline: Move common code for end of final pass to compiler. This patch moves some common code from the individual inline assemblers to the compiler, the code that calls the emit-glue to assign the machine code to the functions scope.	8 years ago
Damien George	dd53b12193	py/emitinline: Move inline-asm align and data methods to compiler. These are generic methods that don't depend on the architecture and so can be handled directly by the compiler.	8 years ago
Damien George	a7fd786a1f	py/emitinline: Embed entire asm struct instead of a pointer to it. This reduces fragmentation, and memory use by 1 word. But more importantly it means the emit_inline_asm_t struct now "derives" from mp_asm_base.	8 years ago
Damien George	3a4ebf5768	esp8266: Enable inline Xtensa assembler. With this patch, @micropython.asm_xtensa can be used on the esp8266 port.	8 years ago
Damien George	f76b1bfa9f	py: Add inline Xtensa assembler. This patch adds the MICROPY_EMIT_INLINE_XTENSA option, which, when enabled, allows the @micropython.asm_xtensa decorator to be used. The following opcodes are currently supported (ax is a register, a0-a15): ret_n() callx0(ax) j(label) jx(ax) beqz(ax, label) bnez(ax, label) mov(ax, ay) movi(ax, imm) # imm can be full 32-bit, uses l32r if needed and_(ax, ay, az) or_(ax, ay, az) xor(ax, ay, az) add(ax, ay, az) sub(ax, ay, az) mull(ax, ay, az) l8ui(ax, ay, imm) l16ui(ax, ay, imm) l32i(ax, ay, imm) s8i(ax, ay, imm) s16i(ax, ay, imm) s32i(ax, ay, imm) l16si(ax, ay, imm) addi(ax, ay, imm) ball(ax, ay, label) bany(ax, ay, label) bbc(ax, ay, label) bbs(ax, ay, label) beq(ax, ay, label) bge(ax, ay, label) bgeu(ax, ay, label) blt(ax, ay, label) bnall(ax, ay, label) bne(ax, ay, label) bnone(ax, ay, label) Upon entry to the assembly function the registers a0, a12, a13, a14 are pushed to the stack and the stack pointer (a1) decreased by 16. Upon exit, these registers and the stack pointer are restored, and ret.n is executed to return to the caller (caller address is in a0). Note that the ABI for the Xtensa emitters is non-windowing.	8 years ago
Damien George	ad297a1950	py: Allow inline-assembler emitter to be generic. This patch refactors some code so that it is easier to integrate new inline assemblers for different architectures other than ARM Thumb.	8 years ago
Damien George	45a6156dfd	esp8266: Enable native emitter for Xtensa arch. This patch allows esp8266 to use @micropython.native and @micropython.viper function decorators. By default the executable machine code is written to the space at the end of the iram1 region. The user can call esp.set_native_code_location() to make the code go to flash instead.	8 years ago
Damien George	8e5aced1fd	py: Integrate Xtensa assembler into native emitter. The config option MICROPY_EMIT_XTENSA can now be enabled to target the Xtensa architecture with @micropython.native and @micropython.viper decorators.	8 years ago
Damien George	fcac4b07f1	py/asmxtensa: Add low-level Xtensa assembler.	8 years ago
Damien George	81316fa411	py/asmbase: Add MP_PLAT_COMMIT_EXEC option for handling exec code. If a port defines MP_PLAT_COMMIT_EXEC then this function is used to turn RAM data into executable code. For example a port may want to write the data to flash for execution. The function must return a pointer to the executable data.	8 years ago
Damien George	c8746e1e72	py: Move arch-specific assembler macros from emitnative to asmXXX.h.	8 years ago
Damien George	c2713592bc	py/emit.h: Remove long-obsolete declarations for cpython emitter.	8 years ago
Damien George	adf3cb5081	extmod/modframebuf: Store underlying buffer object to prevent GC free.	8 years ago
Damien George	5e393007b9	esp8266/mpconfigport_512k: Disable framebuf module for 512k build. The 512k build recently overflowed because of the newly-enabled uselect module. uselect is arguable more important than framebuf for small devices so we disable framebuf to keep the 512k build within its limit.	8 years ago
Damien George	898d4c1217	extmod/modframebuf: Make framebuf implement the buffer protocol. So that one can easily access the underlying data of the frame buffer, eg to write the data out to a display.	8 years ago
Damien George	ad166857bc	esp8266: Refactor to use extmod implementation of software SPI class.	8 years ago
Damien George	1b6d94bccd	stmhal: Refactor to use extmod implementation of software SPI class. This is a pure refactoring (and simplification) of code so that stmhal uses the software SPI class provided in extmod, for the machine.SPI implementation.	8 years ago
Damien George	1eb3c66e91	extmod/machine_spi: Provide reusable software SPI class. So long as a port defines relevant mp_hal_pin_xxx functions (and delay) it can make use of this software SPI class without the need for additional code.	8 years ago
Damien George	d9c839742f	stmhal/hal: Update HALCOMMITS due to change in f7 hal files.	8 years ago
Rami Ali	db5a4e8f3c	stmhal/boards/STM32F7DISC: Define LSE_STARTUP_TIMEOUT. So it compiles with the latest F7 hal.	8 years ago
Rami Ali	6901649f54	stmhal: Declare and initialise PrescTables for F7 MCUs.	8 years ago
Rami Ali	44cb2ff7ab	stmhal: Port of f4 hal commit `1d7fb82` to updated f7 hal.	8 years ago
Rami Ali	821863751f	stmhal: Port of f4 hal commit `09de030` to updated f7 hal.	8 years ago
Rami Ali	e1c6ed634f	stmhal: Port of f4 hal commit `c568a2b` to updated f7 hal.	8 years ago
Rami Ali	b9741cd8f8	stmhal/hal: Update ST32CubeF7 HAL files to V1.1.2. These files originate from the STM32Cube_FW_F7_V1.5.0 software package from ST. Newlines are unixified and trailing whitespace is removed.	8 years ago
Rami Ali	d9677f4098	stmhal/cmsis: Update STM32F7 CMSIS device include files to V1.1.2.	8 years ago
Damien George	080a78b15e	py/compile: Simplify configuration of native emitter.	8 years ago
Damien George	4c7d799b82	stmhal/uart: Add check that UART id is valid for the given board. Previous to this patch trying to construct, but not init, a UART that didn't exist on the target board would actually succeed. Only when initialising the UART would it then raise an exception that the UART does not exist. This patch adds an explicit check that the constructed UART does in fact exist for the given board.	8 years ago
Damien George	aaab6a9921	stmhal/uart: Add support for UART7 and UART8 on F7 MCUs.	8 years ago
Rami Ali	27a503f632	stmhal: Refactor UART configuration to use pin objects. This follows the pattern of other peripherals (I2C, SPI) to specify the pins using pin objects instead of a pair of GPIO port and pin number. It makes it easier to customise the UART pins for a particular board.	8 years ago
puuu	4fc607a1d7	esp8266: Move websocket_helper.py from scripts to modules for frozen BC. websocket_helper.py is used by webrepl. If webrepl is enabled and websocket_helper.py is not frozen bytecode it leads to heap fragmentation.	8 years ago
Damien George	042d5f24d6	tests/extmod/framebuf1: Add basics tests for hline, vline, rect, line.	8 years ago
Damien George	374ed317c5	extmod/modframebuf: Add hline, vline, rect and line methods. These are basic drawing primitives. They work in a generic way on all framebuf formats by calling the underlying setpixel or fill_rect C-level primitives.	8 years ago
Damien George	0db3a41f02	travis: Build STM32 F7 and L4 boards under Travis CI. The STM32 F7 and L4 boards use significantly different code to the F4 boards so it's important to test them with CI. To keep CI build times within a reasonable limit the STM32F4DISC board is no longer built, it's anyway very similar to the standard F4 build for PYBv1.0.	8 years ago
Damien George	fcd10882bd	stmhal/adc: Use constants from new HAL version.	8 years ago
