Posted at 2021-04-29 by JumJum Yes, its just the sending. I'm creating my own build, see https://github.com/jumjum123/EspruinoExtensions/blob/master/General/LEDBoard/makeESPRUINOBOARD.sh Executing in an interrupt, this might help for ESP32. There I have a delay from time to time as I can see with logicanalyzer. Will take some time, but I will check this. |

Some time ago, Gordon added some functionality to espruino which coud be used to control LED Panels.
Today some more panels, up to 128x64 are available for low money. Badly, they need 4 times the data of a 64x32 panel, and we reach a limit what can be done with Espruino itself.
Therefore I gave it a try to add new commands, written in C. Tested and running are versions for Espruino Board, ESP32 and MDBT42Q.
Status is "kind of working for me"

There are some problems with a few flickering pixels. Second problem is powersupply, my old one is working fine, but all I bought last months cause extremly flickering.
