The Pin config setting by IOMUXC_SetPinConfig() is supplied by a
bit pattern. That pattern is specific for a MCU family. In preparation
for supporting the MIMXRT117x family, the constant bit pattern is
replaced by a function call, such that the bit pattern is created
at a single place. The code for this functions was taken from
machine_pin.c.
Note: A working port for the MIMXRT1176 exists already.
- modified pin type from pin_obj_t to machine_pin_obj_t
- created machine_pin.c
- implemented basic version of make-pins.py to genertate pins.c/.h files
automatically; the only alternate function currently supported is GPIO
- added af.csv files for all supported MCUs
- replaced pins.c/pins.h files with pin.csv for all boards
- implemented on/off/high/low/value/init methods
- Implemented IN/OUT/OPEN_DRAIN modes
- modified LDFLAGS for DEBUG build to get usefull .elf file for debugging
