This commit also introduces board directories and moves board
specific config into the appropriate board directory.
boards/stm32f4xx-af.csv was extracted from the STM32F4xx datasheet
and hand-tweaked.
make-pins.py takes boards/stm32f4xx-af.csv, boards/stm32f4xx-prefix.c,
and boards/BOARD-NAME/pins.csv as input and generates the file
build/pins_BOARD_NAME.c
The generated pin file for PYBOARD4 looks like this:
https://gist.github.com/dhylands/9063231
The generated pins file includes all of the supported alternate
functions, and includes upsupported alternate functions as comments.
See the commnet block at the top of stm/pin_map.c for details on
how to use the pin mapper.
I also went ahead and modified stm/gpio.c to use the pin mapper.
Raw REPL mode is activated by CTRL-A, and allows you to more easily
communicate with the pyboard over the serial channel. In particular,
automated communication using, eg, pyserial on the PC side.
Each built-in exception is now a type, with base type BaseException.
C exceptions are created by passing a pointer to the exception type to
make an instance of. When raising an exception from the VM, an
instance is created automatically if an exception type is raised (as
opposed to an exception instance).
Exception matching (RT_BINARY_OP_EXCEPTION_MATCH) is now proper.
Handling of parse error changed to match new exceptions.
mp_const_type renamed to mp_type_type for consistency.
Ultimately all static strings should be qstr. This entry in the type
structure is only used for printing error messages (to tell the type of
the bad argument), and printing objects that don't supply a .print method.
Note: none of these functions are used by STM port, so they're provided
to have parity with pre gc refactor status quo, and in case they will be
needed in the future by some extension writers.
Using PendSV interrupt at lowest priority, code can now raise an
exception during an interrupt by calling pendsv_nlr_jump. The exception
will be raised when all interrupts are finished. This is used to trap
ctrl-C from the USB VCP to break out of running Python code.
