Second SPI for ESP32-S3-DevKitC-1-N32R8V Development Board
Posted: Tue Dec 10, 2024 3:43 pm
I need a second SPI for the ESP32-S3 module, but I see a lot of conflicting information online. Most of the information claims that there are 2 dedicated "fast/hardware" SPI channels on the module - one I've dedicated to work with a screen, but I'd like to assign the second one to work with an Ethernet module.
I was just made aware that according to the documentation:
Thank you
I was just made aware that according to the documentation:
So what pins can I use for the "second" hardware-enabled SPI?"For modules with Octal SPI PSRAM, i.e., modules embedded with ESP32-S3R8 or ESP32-S3R16V, pins IO35, IO36, and IO37 are connected to the Octal SPI PSRAM and are not available for other uses."
Thank you
