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).

cce7119a2b stmhal: Work around crazy bug in USB CDC. 
Packets of 64 bytes length are not send to the host until the following
packet is sent.  Fixed by never sending packets of 64 bytes length.

8a1cab952f py: Fix mp_get_buffer, and use it in more places. 
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.

0aab675108 stmhal: Little hack to dump GC allocation table using pyb.info(). 
Pass a single parameter (doesn't matter what): pyb.info(1), will dump
the GC alloc table.

Tweak pybcdc.inf to match recent changes to pybcdc.h
 2014-04-10 22:51:48 +01:00

3f4898456b stmhal: Add stm module, which contains some constants for the MCU. 
Also contains raw memory read/write functions, read8, read16, read32,
write8, write16, write32.  Can now do:

stm.write16(stm.GPIOA + stm.GPIO_BSRRL, 1 << 13)

This turns on the red LED.

With the new constant folding, the above constants for the GPIO address
are actually compiled to constants (and the addition done) at compile
time.  For viper code and inline assembler, this optimisation will make
a big difference.  In the inline assembler, using these constants would
not be possible without this constant folding.

Damien George
26cf55ae05 Add a check for NULL nlr_top in nlr_jump. 
If no nlr_buf has been pushed, and an nlr_jump is called, then control
is transferred to nlr_jump_fail (which should bail out with a fatal
error).

97790455fe Improve REPL detecting when input needs to continue. 
Full CPython compatibility with this requires actually parsing the
input so far collected, and if it fails parsing due to lack of tokens,
then continue collecting input.  It's not worth doing it this way.  Not
having compatibility at this level does not hurt the goals of Micro
Python.

72d70cb045 unix, stmhal: Consistently use "FileIO" as class name for file objects. 
They correspond to io.FileIO in io module hierarchy (with small caveat
that io.FileIO is raw file and works with bytes, not strings).

27e735fd18 py: Replace stream_p with *stream_p in mp_obj_type_t. 
This is to reduce ROM usage.  stream_p is used in file and socket types
only (at the moment), so seems a good idea to make the protocol
functions a pointer instead of the actual structure.

It saves 308 bytes of ROM in the stmhal/ port, 928 in unix/.

7efc5b3f34 py: Make globals and locals proper dictionary objects. 
Finishes addressing issue #424.

In the end this was a very neat refactor that now makes things a lot
more consistent across the py code base.  It allowed some
simplifications in certain places, now that everything is a dict object.

Also converted builtins tables to dictionaries.  This will be useful
when we need to turn builtins into a proper module.

3996611c1b stmhal: Add home/end cursor support in readline. 
Home/end work in picocom and screen (different codes in those 2
programs).  Also, CTRL-A (for non-empty liny) and CTRL-E act as
home/end.
