Rami Ali	5e1ccddc82	tests/basics: Improve mpz test coverage.	8 years ago
Paul Sokolovsky	91359c8690	tests/struct*: Make skippable.	8 years ago
Damien George	de9cd00b39	py/compile: Add an extra pass for Xtensa inline assembler. It needs an extra pass to compute the size of the constant table for the l32r instructions.	8 years ago
Paul Sokolovsky	bbd0d27a25	zephyr: Enable slice subscription. Required for the testsuite.	8 years ago
Paul Sokolovsky	56a514c193	zephyr/uart_core: Access console UART directly instead of printk() hack. This is required to avoid extra level of output "cooking" ("\r\r\n") and make test infrastructure work. On the other hand, this breaks somewhat Zephyr console abstraction.	8 years ago
Paul Sokolovsky	0c59c30fde	zephyr: Use core-provided keyboard exception object.	8 years ago
Paul Sokolovsky	724b82559d	zephyr/main: Initialize sys.path and sys.argv.	8 years ago
Mike Causer	87e426c7c7	esp8266: Add "erase" target to Makefile, to erase entire flash.	8 years ago
Damien George	48d81c6900	esp8266: Use core-provided keyboard exception object.	8 years ago
Damien George	a770ba147e	stmhal: Use core-provided keyboard exception object.	8 years ago
Damien George	d89cafd5c3	lib/utils/interrupt_char: Use core-provided mp_kbd_exception if enabled. Ultimately all ports that use lib/utils/interrupt_char would enable MICROPY_KBD_EXCEPTION, so this is an interim solution.	8 years ago
Damien George	7f1da0a03b	py: Add MICROPY_KBD_EXCEPTION config option to provide mp_kbd_exception. Defining and initialising mp_kbd_exception is boiler-plate code and so the core runtime can provide it, instead of each port needing to do it themselves. The exception object is placed in the VM state rather than on the heap.	8 years ago
Damien George	979ab4e126	stmhal/usb: Always use the mp_kbd_exception object for VCP interrupt. There's no need to store a separate pointer to this object.	8 years ago
Damien George	f254cfd3c4	stmhal: Rename mp_const_vcp_interrupt to mp_kbd_exception. mp_kbd_exception is now considered the standard variable name to hold the singleton KeyboardInterrupt exception. This patch also moves the creation of this object from pyb_usb_init() to main().	8 years ago
Damien George	29b5879613	tools/pyboard.py: Refactor so target is not reset between scripts/cmd. Previous to this patch pyboard.py would open a new serial connection to the target for each script that was run, and for any command that was run. Apart from being inefficient, this meant that the board was soft-reset between scripts/commands, which precludes scripts from accessing variables set in a previous one. This patch changes the behaviour of pyboard.py so that the connection to the target is created only once, and it's not reset between scripts or any command that is sent with the -c option.	8 years ago
Damien George	1b02565316	stmhal/mpconfigport: Add weak-module links for io, collections, random.	8 years ago
Damien George	7081ea4119	tests/micropython: Get heapalloc_traceback test running on baremetal. When printing exceptions from files sent to a target by pyboard.py the filename in the exception is <stdin>, which differs to when running the script on the PC. So we strip out the filename to make the outputs the same on all targets (see also misc/print_exception.py test).	8 years ago
Lorenz Schmid	a5b3c7e7f9	docs/library/pyb.UART: Moved writechar doc to sit with other writes.	8 years ago
Lorenz Schmid	0caac94b98	docs/library/pyb.UART: Added clarification about timeouts.	8 years ago
Paul Sokolovsky	c16e7eae5e	zephyr: Implement soft reset feature.	8 years ago
Paul Sokolovsky	95fe7a40b3	zephyr: Support raw REPL.	8 years ago
Paul Sokolovsky	403c93053e	py/mpconfig.h: Enable MICROPY_PY_SYS_EXIT by default. sys.exit() is an important function to terminate a program. In particular, the testsuite relies on it to skip tests (i.e. any other functionality may be disabled, but sys.exit() is required to at least report that properly).	8 years ago
Paul Sokolovsky	ee7ad7e8be	esp8266: Add "ota" target to produce firmware binary for use with yaota8266. https://github.com/pfalcon/yaota8266 is a (WIP) OTA-enabled bootloader which doesn't require reserving space 2x size of a firmware.	8 years ago
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
