Hello,
I have written a mapXY function that takes in account the matrix layout ( rows or columns ) and the origin ( top left / top right / bottom left / bottom right ), serpentine or not.
It’s written in coldfusion language, it is close to html and easy to read and translate in arduino or other language.
I have used this to create config files for patching a matrix in glediator, for use with artnet, because their editor is really crappy.
I thought it might be useful for other fastled users.
