ESP32 Full Duplex SPI Protocol

[caller89]

Hi All

I'm really struggling with finding any information or examples on full duplex SPI protocol for ESP32 in Arduino IDE.

I have managed to get this protocol operation on two Arduino boards however due to the ESP32SPISlave library I'm struggling converting this code.

Hoping someone here has done this before.

Thanks

Thanks for sending this through, unfortunately this does not help me , I'm not even sure if that code is IDE.

for something that SPI does so easily, why is it so hard to find any information online about the IDE code
