Can ESP32-S2 support 8-bit parallel port?

ESP32-S2 can be added to support 8-bit parallel port

[moononournation]

Yes, it is similar to RPi Pico. I just not yet have time connect test it. Can you help this?

I have just added a new Arduino_ESP32S2PAR8 data bus, would you please help to check is it work for you?
