ESP32 Forum

I am using HAL and LL to program SPI. The only information I have been able to find that is specific to SPI is comments in the .h files. Is there any other documentation available?

Thanks

The HAL and LL maps reasonably well to the underlying hardware, so have you checked the technical reference manual of the ESP32 you're using already?

Yes, I have been reading the technical reference manual. I was hoping for a users guide similar to that of the API's, or better yet, a demo project.

Thanks

The HAL/LL is not considered public/stable API, hence documentation is sparse and sometimes outdated.
The most definitive source of information appears to often be the IDF drivers' code
