2014-04-21stmhal: Rename USART to UART.Damien George
It's really a UART because there is no external clock line (and hence no synchronous ability, at least in the implementation of this module). USART should be reserved for a module that has "S"ynchronous capabilities. Also, UART is shorter and easier to type :)
2014-04-21stmhal: Add some documentation to I2C, SPI and USART modules.Damien George
2014-04-21stmhal: Improve USART class, to be more like SPI and I2C.Damien George
The three classes I2C, SPI and USART now have a fairly uniform (Python) API. All are constructed, initialised and deinitialised in the same way. They can have most of their parameters set, using keyword arguments. All have send and recv (although slightly different with I2C requiring an address in master mode). recv can do inplace receiving (ie store the data in a previously-created bytearray). It's just polling mode at the moment, but interrupt and DMA would be nice to add.
2014-04-18stmhal: Big cleanup; merge gpio into Pin; make names consistent.Damien George
This is an attempt to clean up the Micro Python API on the pyboard. Gpio functionality is now in the Pin object, which seems more natural. Constants for MODE and PULL are now in pyb.Pin. Names of some classes have been adjusted to conform to CamelCase. Other miscellaneous changes and clean up here and there.
2014-04-15stmhal: Wrap skin-named-usarts in PYBV10 #if.Damien George
2014-04-14stmhal: Improved usart module a bit.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.
2014-03-30stmhal: Unify naming of HW config; make SD detect configurable.Damien George
All board config macros now begin with MICROPY_HW_. Renamed PYBv10 to PYBV10, since macros should be all uppercase. Made SDCARD_DETECT configurable in mpconfigport.h, so that the SD detect pin can be easily configured.
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.
