is there a way to drive the adafruit 32x32 LED Matrix display with the esp8266 directly without other MCUs, i have seen some examples done, but no code. Anybody know how to do this??

Look at the matrix example of you need x,y addressing. You are talking about the neopixel matrix, correct?

sorry it is the arduino matrix display not neopixel. https://learn.adafruit.com/32x16-32x32-rgb-led-matrix/overview
would have not been my choice but trying to help some students, seems overly complex
i see this example, but why does it need a arduino nano?? https://github.com/VGottselig/ESP8266-RGB-Matrix-Panel
it seems to be using the nano as a shift register, is the nano not capable of doing this? Not fast enough??

Esp8266 is problematic when needing accurately timed pin changes, a single pin I use hardware features, more than one is the issue
