* stmhal/dma.c: Modify dma_init() to accept init struct as an argumentblmorris2015-06-24
| | | | | | | | This removes hard-coded DMA init params from dma_init(), instead defining these parameters in a DMA_InitTypeDef struct that gets passed as an argument to dma_init() This makes dma_init more generic so it can be used for I2S and SD Card, which require different initialization parameters.
* stmhal: Reorganise code for parsing keyword args in I2C methods.Damien George2015-06-22

* py: Overhaul and simplify printf/pfenv mechanism.Damien George2015-04-16
| | | | | | | | | | | | | | | | | | | | | | Previous to this patch the printing mechanism was a bit of a tangled mess. This patch attempts to consolidate printing into one interface. All (non-debug) printing now uses the mp_print* family of functions, mainly mp_printf. All these functions take an mp_print_t structure as their first argument, and this structure defines the printing backend through the "print_strn" function of said structure. Printing from the uPy core can reach the platform-defined print code via two paths: either through mp_sys_stdout_obj (defined pert port) in conjunction with mp_stream_write; or through the mp_plat_print structure which uses the MP_PLAT_PRINT_STRN macro to define how string are printed on the platform. The former is only used when MICROPY_PY_IO is defined. With this new scheme printing is generally more efficient (less layers to go through, less arguments to pass), and, given an mp_print_t* structure, one can call mp_print_str for efficiency instead of mp_printf("%s", ...). Code size is also reduced by around 200 bytes on Thumb2 archs.
* py: Remove mp_obj_str_builder and use vstr instead.Damien George2015-01-21
| | | | | | | | | | | | With this patch str/bytes construction is streamlined. Always use a vstr to build a str/bytes object. If the size is known beforehand then use vstr_init_len to allocate only required memory. Otherwise use vstr_init and the vstr will grow as needed. Then use mp_obj_new_str_from_vstr to create a str/bytes object using the vstr memory. Saves code ROM: 68 bytes on stmhal, 108 bytes on bare-arm, and 336 bytes on unix x64.

* stmhal: Document physical pins for SPI, I2C, UART busses.Damien George2014-05-04

* Add license header to (almost) all files.Damien George2014-05-03
| | | | | | | 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/.
* stmhal: Fix typos in class documentation.Damien George2014-05-03

* unix,stmhal: Make "mpconfig.h" be first included, as other headers depend on it.Paul Sokolovsky2014-05-02

* stmhal: Add documentation in comments, and script to generate HTML.Damien George2014-04-29
| | | | | | | | | | | | | | 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.

* stmhal: Improved configurability for I2C and SPI busses.Damien George2014-04-20
| | | | | The HAL handles for the I2C/SPI objects are rather large, so we don't want to unnecessarily include them.

| | | | Also some updates to compile with latest changes to core py.
* stmhal: Update ADC, DAC and I2C objects to use new buffer protocol.Damien George2014-04-18
| | | | | | | | | | 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.
* stmhal: Fix C bindings of I2C.read/write.Damien George2014-04-16

* stmhal: Add I2C functions for pure master read/write.Damien George2014-04-16

* stmhal: Add I2C.scan method, to scan all devices on the bus.Damien George2014-04-15
| | | | Simple way to find the address of an attached I2C device.
* py: Fix mp_get_buffer, and use it in more places.Damien George2014-04-13
| | | | | 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.
* stmhal: Move I2C objects to ROM.Damien George2014-04-12

* py: Change nlr_jump to nlr_raise, to aid in debugging.Damien George2014-04-05
| | | | | | This does not affect code size or performance when debugging turned off. To address issue #420.
* Merge map.h into obj.h.Damien George2014-03-30
| | | | | | 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.
* Rename rt_* to mp_*.Damien George2014-03-30
| | | | | | | 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.
* py: Rename old const type objects to mp_type_* for consistency.Damien George2014-03-29

* stmhal: Use rt_check_nargs to check number of arguments.Damien George2014-03-26

* Remove mp_obj_type_t.methods entry and use .locals_dict instead.Damien George2014-03-26
| | | | | | | | | | | | | | | | | | | | | | 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.
