""" """
Read in the cmsis/devinc/stm32f405xx.h header, extract relevant constants, This script reads in the given CMSIS device include file (eg stm32f405xx.h),
and create modstmconst.c. extracts relevant peripheral constants, and creates qstrs, mpz's and constants
for the stm module.
This is not part of the automatic build process because stm32f405xx.h isn't
expected to change. After generating the file, some manual intervention is
needed to copy the new qstr definitions to qstrdefsport.h.
