2017-09-06ports: Make new ports/ sub-directory and move all ports there.Damien George
This is to keep the top-level directory clean, to make it clear what is core and what is a port, and to allow the repository to grow with new ports in a sustainable way.
2017-08-30all: Convert remaining "mp_uint_t n_args" to "size_t n_args".Damien George
This is to have consistency across the whole repository.
2017-08-13all: Raise exceptions via mp_raise_XXXJavier Candeira
- Changed: ValueError, TypeError, NotImplementedError - OSError invocations unchanged, because the corresponding utility function takes ints, not strings like the long form invocation. - OverflowError, IndexError and RuntimeError etc. not changed for now until we decide whether to add new utility functions.
2017-07-31all: Use the name MicroPython consistently in commentsAlexander Steffen
There were several different spellings of MicroPython present in comments, when there should be only one.

Otherwise, they serve reoccurring source of copy-paste mistakes and breaking nanbox build.
2016-09-05stmhal/dac: Fix DAC (re-)initialisation by resetting DMA.Peter Hinch
Fixes issue #2176.
2016-05-31stmhal/dac: DAC deinit() method added.Peter Hinch
2016-05-05stmhal: L4: Adapt DMA to be able to support STM32L4 MCU series.Tobias Badertscher
The main thing is to change the DMA code in a way that the structure DMA_Stream_TypeDef (which is similar to DMA_Channel_TypeDef on stm32l4) is no longer used outside of dma.c, as this structure only exists for the F4 series. Therefore I introduced a new structure (dma_descr_t) which handles all DMA specific stuff for configuration. Further the periphery (spi, i2c, sdcard, dac) does not need to know the internals of the dma.
2016-01-11py: Change first arg of type.make_new from mp_obj_t to mp_obj_type_t*.Damien George
The first argument to the type.make_new method is naturally a uPy type, and all uses of this argument cast it directly to a pointer to a type structure. So it makes sense to just have it a pointer to a type from the very beginning (and a const pointer at that). This patch makes such a change, and removes all unnecessary casting to/from mp_obj_t.
2015-12-02stmhal: Put all DMA channel & stream definitions in dma.hDave Hylands
2015-10-13stmhal: Allow to set bits resolution for DAC; 8 is default, can have 12.Damien George
This patch allows to configure the DAC resolution in the constructor and in the init function, eg: dac = DAC(1, bits=12). The default resolution is 8 bits for backwards compatibility. The bits sets the maximum value accepted by write and write_timed methods, being 2**bits - 1. When using write_timed with 12-bit resolution, the input buffer is treated as an unsigned half-word array, typecode 'H'. See PR #1130 for discussion.
2015-07-30stmhal: Replace #include "stm32f4xx_hal.h" with #include STM32_HAL_H.Dave Hylands
2015-07-22stmhal: Allow ADC.read_timed to take Timer object in place of freq.Damien George
This allows a user-specified Timer for the triggering of the ADC read, mirroring the new behaviour of DAC.write_timed. Addresses issue #1129.
2015-07-21stmhal: Allow DAC.write_timed to take Timer object in place of freq.Damien George
This allows the DAC to use a user-specified Timer for the triggering (instead of the default Timer(6)), while still supporting original behaviour. Addresses issues #1129 and #1388.
2015-07-21stmhal: Clean up DAC code a little.Damien George
2015-04-18stmhal: Exclude code for those timers that don't exist in the hardware.Damien George
2015-04-16stmhal: Use new %q format to print qstr's in a few more places.blmorris
Saves 68 bytes.
2015-01-01stmhal: Prefix includes with py/; remove need for -I../py.Damien George
2014-10-26stmhal: Allow DAC object to be initialised from a pin.Damien George
Eg: dac = DAC(Pin.board.X5)
2014-08-30Change some parts of the core API to use mp_uint_t instead of uint/int.Damien George
Addressing issue #50, still some way to go yet.
2014-08-06stmhal: Update STM32Cube F4 HAL driver to V1.3.0.Damien George
This patch updates ST's HAL to the latest version, V1.3.0, dated 19 June 2014. Files were copied verbatim from the ST package. Only change was to suppress compiler warning of unused variables in 4 places. A lot of the changes from ST are cosmetic: comments and white space. Some small code changes here and there, and addition of F411 header. Main code change is how SysTick interrupt is set: it now has a configuration variable to set the priority, so we no longer need to work around this (originall in system_stm32f4xx.c).
2014-08-05stmhal: Wrap DAC module and os.urandom in relevant #if's.Damien George
2014-07-03Rename machine_(u)int_t to mp_(u)int_t.Damien George
See discussion in issue #50.
2014-06-19Prefix ARRAY_SIZE with micropython prefix MP_Emmanuel Blot
2014-05-19stmhal: Fix DAC documentation: need to convert float to int for buf.Damien George
2014-05-19stmhal: Fix write_timed function for DAC(2).Damien George
Addresses issue #617.
2014-05-03Add license header to (almost) all files.Damien George
Blanket wide to all .c and .h files. Some files originating from ST are difficult to deal with (license wise) so it was left out of those. Also merged modpyb.h, modos.h, modstm.h and modtime.h in stmhal/.
2014-05-02Merge branch 'master' of github.com:micropython/micropythonDamien George
2014-05-02stmhal: Add documentation for DAC and Timer classes.Damien George
2014-05-02unix,stmhal: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky
2014-04-29stmhal: Add documentation in comments, and script to generate HTML.Damien George
Decided to write own script to pull documentation from comments in C code. Style for writing auto generated documentation is: start line with /// and then use standard markdown to write the comment. Keywords recognised by the scraper begin with backslash. See code for examples. Running: python gendoc.py modpyb.c accel.c adc.c dac.c extint.c i2c.c led.c pin.c rng.c servo.c spi.c uart.c usrsw.c, will generate a HTML structure in gendoc-out/. gendoc.py is crude but functional. Needed something quick, and this was it.
2014-04-26Simplify names for argcheck.c / arg parsing.Damien George
2014-04-26Add ARRAY_SIZE macro, and use it where possible.Damien George
2014-04-21stmhal: Make DAC dynamically allocate instances; rename dma->write_timed.Damien George
2014-04-20stmhal: Add SPI class.Damien George
Also some updates to compile with latest changes to core py.
2014-04-18stmhal: Update ADC, DAC and I2C objects to use new buffer protocol.Damien George
Main reason for expanding buffer protocol API was to support writes to a buffer in ADC module (see read_timed). With this change you can now create an array of arbitrary type and ADC.read_timed will store into that array in the correct format (byte, int, float). I wonder though if all these changes were really worth it to support just this function. Hopefully this enhanced buffer protocol API (with typecode specified) will be used elsewhere.
2014-04-15stmhal: Add ADC function to read data at a given frequency.Damien George
Reads ADC values into a bytearray (or similar) at a fixed rate. Needs a better name and improved API. Also fix up DAC dma function (which also needs a better name and API).
2014-04-13py: Fix mp_get_buffer, and use it in more places.Damien George
Must use mp_obj_get_type to get the type of an object. Can't assume mp_obj_t is castable to mp_obj_base_t.
2014-04-05py: Change nlr_jump to nlr_raise, to aid in debugging.Damien George
This does not affect code size or performance when debugging turned off. To address issue #420.
2014-03-30Merge map.h into obj.h.Damien George
Pretty much everyone needs to include map.h, since it's such an integral part of the Micro Python object implementation. Thus, the definitions are now in obj.h instead. map.h is removed.
2014-03-30Rename rt_* to mp_*.Damien George
Mostly just a global search and replace. Except rt_is_true which becomes mp_obj_is_true. Still would like to tidy up some of the names, but this will do for now.
2014-03-26stmhal: Use rt_check_nargs to check number of arguments.Damien George
2014-03-26Remove mp_obj_type_t.methods entry and use .locals_dict instead.Damien George
Originally, .methods was used for methods in a ROM class, and locals_dict for methods in a user-created class. That distinction is unnecessary, and we can use locals_dict for ROM classes now that we have ROMable maps. This removes an entry in the bloated mp_obj_type_t struct, saving a word for each ROM object and each RAM object. ROM objects that have a methods table (now a locals_dict) need an extra word in total (removed the methods pointer (1 word), no longer need the sentinel (2 words), but now need an mp_obj_dict_t wrapper (4 words)). But RAM objects save a word because they never used the methods entry. Overall the ROM usage is down by a few hundred bytes, and RAM usage is down 1 word per user-defined type/class. There is less code (no need to check 2 tables), and now consistent with the way ROM modules have their tables initialised. Efficiency is very close to equivaluent.
2014-03-26Change mp_method_t.name from const char * to qstr.Damien George
Addresses issue #377.
