GlowBit 8x8 Matrix: Is there a built-in function to rotate the display 90 degrees?

I’ve already soldered one of the matrix to fit my project and would love to be able to rotate the images it displays by 90 degrees counter-clockwise. Is there a built in function to do this? Or alternatively a fairly simple do this in code.

Thanks in advance.


Hi James,

I’ve just come across your post - looks like we’ve missed this one!

Which matrix are you using? In principle, this is a fairly well solved and there a few software libraries or and pre-written functions that can perform 90° rotations. Eg. checkout the transform() function in this library:
