I am guessing he is getting a decent refresh rate too, as the video looks fine to me.
IDK if he is using matrix driver electronics - he says he is using 2x 74HCT245 (octal level shifter) and 1x 74AHCT125 (quad level shifter)
Even if he is, is this not way beyond what would be possible with rpi-rgb-led-matrix?
@evilC
Could you clarify what exactly surprises you? I haven’t watched the video, but I have no doubt that a Pi Pico can control two 128x64 matrices.
Ah, hold on, I did not realize that the pico was not an SBC. I guess that makes all the difference.
That explains how he is able to get jitter free, high refresh animations, despite it not being as powerful as something like a zero 2w, which I struggled to get a refresh rate rate on which was high enough and stable enough to look good in video recordings.
