In reverse engineering map mode I have 2 pixels lighting at the same time in 1 column but 2 different rows, example in column 0, row 1 and 2 light together, then 3 and 4 etc. The pattern on this panel is top to bottom as opposed to the more common left to right.
Nope. I think some of the I/O lines are different polarity. Too bad cause they are very common panels. Would be nice to be able to change polarity easily for testing.
I’ve ought them locally. What’s worse, seller uses Chinese controllers that work with all panel types, and he can’t be sure that he will get those same panels the next time they arrive, otherwise I could be able to send you one.
I’ve lost track of where mine came from since I purchase led modules from random companies. If they didn’t work for the adafruit library, I’d move on to some other company trying to find one that worked.
BUT
It could have been Shenzhen Lightwell here module site
They have SMD P10 1/2 scan outdoor 16x32 Hub75 RGB modules. Unfortunately I can’t be sure.
