ESP32S2 - SPI HAL or LL Example

[KWolfe81]

Does anyone have a simple example of getting the SPI module to dance using just the HAL or LL layers? Ideally, master mode with interrupts, but I'll take what I can get.

Context: I'm looking to utilize the ESP32S2's SPI peripheral but the IDF drivers have way too many RTOS calls and protections. They're way too slow, and further, I can guarantee thread safety in other ways.

Thanks!
