Qlc+ sends pixel information according to how the device is defined. 3 values define r/g/b of one pixel. We need to map the image pixels to our actual LEDs, because they are not arranged in lines.
This was a technical spike to try out dividing the LED sign into a matrix of rows and columns. => This is the project I went live with: https://github.com/pnolle/SnipDrop_Esp32Wifi
Incoming image pixels are X and Y. The numbering comes from a random matrix drawn with Matlab (https://github.com/pnolle/write_numbers_in_circle).
