I’m trying to use PlatformIO with samd51 (Adafruit Grand Central M4) and I facing something that let me think code is incomplete.
In some .h header there are some structure define, useful to initialize DMA channels, that are never used (no reference between them and mapping on processor memory).
Also there is no function to reset WDT, program timers and so on. Everything must be done directly using cpu mapping registers.
Adafruit suggest to install both Arduino and it’s own samd library (latter is the one integrated here I think).
I’m wondering maybe PlatformIO should include something more to let Grand Central to be programmed easily?
Thanks for attention
