* extmod/utime_mphal: sleep_us/ms(): Don't wait on negative argument.Paul Sokolovsky2016-10-14
|
* stmhal/modutime: Refactor to use extmod/utime_mphal.c.Paul Sokolovsky2016-10-14
| | | | | This includes making sure that utime_mphal's sleep_ms() and sleep_us() don't sleep on negative arguments.
* extmod/utime_mphal: Factor out implementations in terms of mp_hal_* for reuse.Paul Sokolovsky2016-10-14
| | | | | | As long as a port implement mp_hal_sleep_ms(), mp_hal_ticks_ms(), etc. functions, it can just use standard implementations of utime.sleel_ms(), utime.ticks_ms(), etc. Python-level functions.
* py/vstr: Combine vstr_new_size with vstr_new since they are rarely used.Damien George2016-10-14
| | | | | | | Now there is just one function to allocate a new vstr, namely vstr_new (in addition to vstr_init etc). The caller of this function should know what initial size to allocate for the buffer, or at least have some policy or config option, instead of leaving it to a default (as it was before).
* esp8266: Enable micropython.alloc_emergency_exception_buf().Damien George2016-10-14
|
* tests/micropython: Add tests for heap_lock, and emergency exceptions.Damien George2016-10-14
|
* qemu-arm: Remove SRC_TEST_C from SRC_QSTR list, it's not needed.Damien George2016-10-14
| | | | And it gives problems with header dependencies for auto-qstr generation.
* qemu-arm: Enable lots of extmods and enable tests for them.Damien George2016-10-14
| | | | | The qemu-arm port is used for testing of ARM Thumb architecture on a desktop so should have many features enabled.
* stmhal/pybstdio: Use size_t instead of mp_uint_t.Damien George2016-10-14
|
* tests/extmod/vfs_fat: Replace asserts with prints and expected outputs.Alex March2016-10-13
|
* extmod/modujson: Fix nanbox build.Damien George2016-10-13
|
* tests/extmod: Add test for ujson.load().Damien George2016-10-13
|
* extmod/modujson: Implement ujson.load() to load JSON from a stream.Damien George2016-10-13
| | | | | | | This refactors ujson.loads(s) to behave as ujson.load(StringIO(s)). Increase in code size is: 366 bytes for unix x86-64, 180 bytes for stmhal, 84 bytes for esp8266.
* zephyr: Add copyright blurbs.Paul Sokolovsky2016-10-12
|
* zephyr/mpconfigport.h: Fix rebasing artifacts.Paul Sokolovsky2016-10-12
|
* zephyr: Implement the help() function.Daniel Thompson2016-10-12
| | | | | | | | The boot issue text mentions a help() function and encourages the user to run it. It is very disconcerting to find that the function does not exist... Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org>
* zephyr/Makefile: Be sure to extra qstr's from port sources.Paul Sokolovsky2016-10-12
|
* README: Mention _thread module availability in select ports.Paul Sokolovsky2016-10-12
|
* tools: Upgrade upip to 1.1.3.Paul Sokolovsky2016-10-12
| | | | | Initial support for running on a baremetal, low-heap systems (like esp8266), using Python module interface.
* lib/utils/pyexec: Don't treat SystemExit as "forced exit".Paul Sokolovsky2016-10-12
| | | | | | "Forced exit" is treated as soft-reboot (Ctrl+D). But expected effect of calling sys.exit() is termination of the current script, not any further and more serious actions like mentioned soft reboot.
* esp8266: Enable importing of precompiled .mpy files.Damien George2016-10-12
|
* esp8266: Enable sys.{stdin,stdout,stderr}.buffer for raw serial access.Damien George2016-10-12
|
* py/lexer: Remove unnecessary code, and unreachable code.Damien George2016-10-12
| | | | | | | | | Setting emit_dent=0 is unnecessary because arriving in that part of the if-logic will guarantee that emit_dent is already zero. The block to check indent_top(lex)>0 is unreachable because a newline is always inserted an the end of the input stream, and hence dedents are always processed before EOF.
* py/compile: Remove debugging code for compiler dispatch.Damien George2016-10-12
| | | | | It was a relic from the days of developing the compiler and is no longer needed, and it's impossible to trigger via a test.
* esp8266/mpconfigport: Enable MICROPY_PY_BUILTINS_SLICE_ATTRSRadomir Dopieralski2016-10-11
|
* tests/extmod/vfs_fat: Test coverage for remove() and rmdir().Alex March2016-10-11
|
* extmod/vfs_fat: Add file and directory checks for remove and rmdir.Alex March2016-10-11
|
* extmod/machine_i2c: Use writes not reads in i2c.scan().Radomir Dopieralski2016-10-11
| | | | | | | As per discussion in #2449, using write requests instead of read requests for I2C.scan() seems to support a larger number of devices, especially ones that are write-only. Even a read-only I2C device has to implement writes in order to be able to receive the address of the register to read.
* docs/reference: Add constrained.rst doc.Peter Hinch2016-10-11
| | | | | It contains detailed information about writing scripts to run efficiently on microcontrollers (and other constrained systems).
* extmod/uzlib: Update to upstream v2.1.Paul Sokolovsky2016-10-11
| | | | | | | | Adds check that LZ offsets fall into the sliding dictionary used. This catches a case when uzlib.DecompIO with a smaller dictionary is used to decompress data which was compressed with a larger dictionary. Previously, this would lead to producing invalid data or crash, now an exception will be thrown.
* py/objint: Use size_t for arguments that measure bytes/sizes.Damien George2016-10-11
|
* py: Factor duplicated function to calculate size of formatted int.Damien George2016-10-11
|
* py/mpz: Use assert to verify mpz does not have a fixed digit buffer.Damien George2016-10-11
|
* py/mpz: In divmod, replace check for rhs!=0 with assert.Damien George2016-10-11
| | | | The check for division by zero is made by the caller of this function.
* tests: Improve test coverage of py/compile.c.Damien George2016-10-11
|
* py/compile: Remove unreachable code.Damien George2016-10-11
|
* tests/micropython: Add test for micropython.opt_level() function.Damien George2016-10-11
|
* py/modmicropython: Add micropython.opt_level([value]) function.Damien George2016-10-11
| | | | This allows to get/set at runtime the optimisation level of the compiler.
* zephyr: Add Ctrl+C handling.Paul Sokolovsky2016-10-10
|
* zephyr/zephyr_getchar: Add support for Ctrl+C handling.Paul Sokolovsky2016-10-10
| | | | Patch on top of upstream Zephyr console helpers.
* zephyr/main: Execute main.py frozen module on boot, if available.Paul Sokolovsky2016-10-10
|
* zephyr: Enable frozen modules support.Paul Sokolovsky2016-10-10
|
* zephyr: Enable stack checking and micropython.mem_info().Paul Sokolovsky2016-10-10
|
* zephyr: Add README.Paul Sokolovsky2016-10-10
|
* docs/wipy: Correct deep sleep current figure.daniel2016-10-10
|
* zephyr: Use recently added "make outputexports" Zephyr target.Daniel Thompson2016-10-10
| | | | | | | | The outputexpors target, which exports Zephyr environment variables, was recently added to Zephyr. By exploiting this feature we can hugely simplify the build system, improving robustness at the same time. Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org>
* zephyr/Makefile: Automatically derive target-specific CFLAGS.Paul Sokolovsky2016-10-10
| | | | | By tricking Zephyt arch Makefiles compute them for us (not just for Zephyr). This make potentially break as Zephyr evolves.
* zephyr: Support extra make targetsDaniel Thompson2016-10-10
| | | | | | | The two variables, GENERIC_TARGETS and CONFIG_TARGETS come, respectively, from the the lists shown during "make help" and "make kconfig-help". Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org>
* zephyr: Automatically derive ARCH.Daniel Thompson2016-10-10
| | | | | | | | Currently to compile for anything that except ARCH=x86 we have to provide ARCH via the environment or make arguments. We can do better than that! Signed-off-by: Daniel Thompson <daniel.thompson@linaro.org>
* zephyr: Switch to microkernel, required for network to work in background.Paul Sokolovsky2016-10-10
