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.
