Hi,
sorry this took a while, only just got around to playing with this. Thank you for all the info!
I think the panel I have might be different - mine weirdly enough only has address pins A and B, which doesn’t make any sense to me. The pins that are C, D, and E in the picture above are “NC”, “GND”, and “GND” respectively on my matrix.
I got the matrix addressing things correctly on the X axis, but on the Y axis I’m clearly missing addressing bits:
Can you tell from this how the matrix should be set up?
Cheers
Rob
