The mux pattern is not correct for your panel. Can you please post the complete code?

can you please check your wiring of Pin D? You already had all rows working... Now it looks like it is stuck on the 2nd pair of rows.

Do you use `setFastUpdate(true)`? Does it make a difference?

@Ponkabonk I'm glad the problem is solved, but `setFastUpdate(false)` wasn't meant as solution. Can you provide the complete code of an example that shows the issue?

So, this is what your code produces with fast_update enabled:  and disabled:  You can see two pauses in the first one on...

Instead of using a regular interval of 4ms you could also add a pause of 1ms after each execution:  This would result in about 12ms for...

Also the change from color steps to color bits should be mentioned ;) The time the LEDs stay on is now basically half as long as before for the first...

Even with the default `PxMATRIX_COLOR_DEPTH 4` , `display(x)` now takes four times as long as before for the most significant color bit. Maybe it would be better to use the...

Basically, there are a lot of things to consider when switching from regular pwm to binary pwm. Let's say you have 3 bit / 8 steps and 100% brightness. For...

I also wouldn't mind a technical section in the readme :)
