Title: Which pins can I use for SPI?
Post by: sravyts on March 03, 2020, 11:25:03 AM

Hello
I would like to use the OLIMEX ESP32-EVB to communicate with an external ADC (the MCP3909 from microchip). Which pins can I use for this purpose?
Thanks!

I'd recommend first reading about ESP32 and ADC here:

https://docs.espressif.com/projects/esp-idf/en/latest/api-reference/peripherals/adc.html

And then check this image for the ESP32 pinout:
