2014-05-03stmhal: Fix typos in class documentation.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: Add some documentation to I2C, SPI and USART modules.Damien George
2014-04-21stmhal, SPI and I2C: Improvements to functionality and consistency.Damien George
2014-04-20stmhal: Improved configurability for I2C and SPI busses.Damien George
The HAL handles for the I2C/SPI objects are rather large, so we don't want to unnecessarily include them.
2014-04-20Fix i2c and spi to compile for Netduino Plus 2Dave Hylands
2014-04-20stmhal: Tidy up and improve consistency across modules.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.
2014-04-16stmhal: Fix C bindings of I2C.read/write.Damien George
2014-04-16stmhal: Add I2C functions for pure master read/write.Damien George
2014-04-15stmhal: Add I2C.scan method, to scan all devices on the bus.Damien George
Simple way to find the address of an attached I2C device.
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.
2014-04-12stmhal: Move I2C objects to ROM.Damien George
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.
2014-03-29py: Rename old const type objects to mp_type_* for consistency.Damien George
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.
2014-03-25stmhal: Add I2C support; change accel driver to use new I2C.Damien George
