I feel the need… the need for hardware SPI

80MHz! That’s fast!

A couple of people commented on the slowness of the display update on the previous Arduino Nano ESP32 video.

I had completely missed the fact that the library I was using would default to software SPI unless you passed in an SPI object.

I guess the library is aimed at the lowest common denominator and they just want it to work for everyone. But there’s no restrictions in the ESP32-S3 on the pins that can be used for SPI.

It’s a very short video - but look at the speed difference!
