Damien George 4d7f4eb6a9 stmhal: Add ADC function to read data at a given frequency.
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).

Damien George ea13f407a3 py: Change nlr_jump to nlr_raise, to aid in debugging.
This does not affect code size or performance when debugging turned off.

To address issue #420.

Damien George df6567e634 Merge map.h into obj.h.
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.

Damien George d17926db71 Rename rt_* to mp_*.
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.

Damien George eed6f26bed stmhal: Use rt_check_nargs to check number of arguments. 2014-03-26 22:46:03 +00:00
Damien George 9b196cddab Remove mp_obj_type_t.methods entry and use .locals_dict instead.
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.

Damien George da5e269e51 stmhal: Make pyb.ADC the ADC class (not a function). 2014-03-24 19:27:13 +00:00
Dave Hylands 1403298a65 stmhal - fixed up adc stuff
Added support for the ADC channels and mappings to make_pins.py

I'm not sure if the hal properly deals with the channel 16/18 differences
between the 40x and 42x. It seems to deal with it partially. This particular
aspect will need testing on a 42x or 43x.
