SPI input enhancement

[ghhann]

First congratulations on your excellent work in this project.

Esp32 can be put into slave mode and can handle SPI
Communications. I’m thinking of an adsfruit airlift where they add WiFi to a project for IOT packets.

The new UNO also has an esp32 chip on board.

I was wondering if you could add SPI communication to your project.

I’m thinking of the commanderx16 project that has available and other new retro computers.

All my best
