I didn't realise that arduino already built this tool. https://ledmatrix-editor.arduino.cc But I'll keep this project up for curiosity This project is for the Arduino UNO R4 WiFi matrix LED. You're able to loadFrame() with an array of 3 uint32_t integers. It's a little annoying to work out the bit strings needed to produce the image I want on paper every single time so I made this small tool to make the job easier. https://docs.arduino.cc/tutorials/uno-r4-wifi/led-matrix/ This project allows you to create an image on the LED panel by clicking and dragging on lights you want to toggle. You can then pull the three integers from either the "Bits" or "Hex" field and directly load them onto the LED matrix on the R4 WiFi. The existing tool I found only had support for an 8x8 matrix and the R4 WiFi has a 12x8 matrix. Try: 0x3184a444 0x44042081 0x100a0040 (you can paste the whole code into any of the change int slots) Keybinds: Click and drag - edit C - clear Arrow keys - translate
