This allows a user-specified Timer for the triggering of the ADC read,
mirroring the new behaviour of DAC.write_timed.
Addresses issue #1129.
stmhal: Allow DAC.write_timed to take Timer object in place of freq.2015-07-21T22:39:49+00:00Damien Georgedamien.p.george@gmail.com2015-07-21T22:37:45+00:00urn:sha1:abc24c187614e358faa10ed6a3e239151f70b9f8
This allows the DAC to use a user-specified Timer for the triggering
(instead of the default Timer(6)), while still supporting original
behaviour.
Addresses issues #1129 and #1388.
stmhal: Actually disable unhandled timer interrupts.2015-04-28T07:17:05+00:00Dave Hylandsdhylands@gmail.com2015-04-28T07:17:05+00:00urn:sha1:fdcb3b7ebbb611497866123ec050fc99e5185cd8stmhal: Reset the timer counter to zero after changing the auto reload.2015-04-22T22:31:56+00:00Dave Hylandsdhylands@gmail.com2015-04-22T22:01:25+00:00urn:sha1:fd787c5e4ed369ddf8a178a62b6faf8a421e2bbc
Because if the counter is above the new value of the auto-reload register
then it may be a long time until the timer wraps around.

py: Overhaul and simplify printf/pfenv mechanism.2015-04-16T14:30:16+00:00Damien Georgedamien.p.george@gmail.com2015-04-09T22:56:15+00:00urn:sha1:7f9d1d6ab923096582622b700bedb6a571518eac
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.
stmhal: Fix a bug related to unhandled channel interrupts.2015-03-20T23:40:50+00:00Dave Hylandsdhylands@gmail.com2015-03-10T06:44:26+00:00urn:sha1:49d8e5ebaa195b0227aa04332749f7910d72d1ff
This also cleans up spurious interrupts which happen at timer
initilaization time.
