Interstate75w - setting individual pixels

Hello all,

Is it feasible to update a led matrix display (say 64x32) pixel by pixel? I.e., one would have to set the pen, paint that pixel, and then repeat for all 2048 pixels. How long would that take?

The background to the question is that once I’ve drawn something on the display, I then want to change colours of individual pixels. So I’m planning to write a 64x32 array to the screen, modify the array, and then write it again.

It’s perfectly feasible; one of the examples (rainbow.py) does precisely this (and on my 32x32 panel, it says it takes 38ms / frame)
