Is anybody working on a VGA driver ?

Howdy,
With respect to this article:

https://en.wikipedia.org/wiki/Video_Graphics_Array

Can you elaborate on what you mean by "VGA"? Are you looking for circuitry and software to allow an ESP32 to drive a VGA compatible desktop monitor or projector?

I would guess he means something similar to https://github.com/smaffer/vgax but boosted by esp32 horsepower

@kolban, I would like to connect a VGA Monitor to my ESP32.
ESP32 has to support VSync, HSync and r/g/b for 7 colors.
If RGB is too heavy, I would start with b/w.
HW should not be a problem, some resisitors to create a "levelshifter" should work.
Creating syncs is not the big problem. But how would we create pixel data.
There are some ideas using SPI on specified frequency to support at least black/white.
@WiFive, I'll take a closer look to the arduino port. If Arduino can do, there should be a way for ESP32

Only a hint:
You should take a 8-bit IF for GLCD and merge together

A lot of work I think..

For everyone wanting the same and finding this thread:
There is a youtube video on this topic that achieved some impressive results using out of specs I2S stuff: https://youtu.be/G70CZLPjsXU
