Decided to write own script to pull documentation from comments in C code.
Style for writing auto generated documentation is: start line with ///
and then use standard markdown to write the comment. Keywords
recognised by the scraper begin with backslash. See code for examples.
Running: python gendoc.py modpyb.c accel.c adc.c dac.c extint.c i2c.c
led.c pin.c rng.c servo.c spi.c uart.c usrsw.c, will generate a HTML
structure in gendoc-out/.
gendoc.py is crude but functional. Needed something quick, and this was
it.
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.
