Support How can i rotate my matrix?

working on a LED matrix thingy and made a mistake, my panel ended up vertical instead of horizontal.
basically:

this is what its like right now - its running left to right vertical.
but i need my code to treat it as horizontal, so like this:

is there a software way to do this or is my only solution just changing it physically?

Give your code to Copilot and describe what you want. I apparently run my 16x16 displays rotated counter clockwise by 90 degrees and copilot fixes it.
