}I’m having problems with illuminating more than 31 addressable LEDs.
The above code has numPix=16.
I have changed it to 4 and 8 with no problems. 16 to 24 without issues too. But it’s stuck at 31. I can parallel more strips and even two 8x8 matrix with only 31 illuminating on each.
At first, I thought it was my power supply 9V 1.5A.
So tried another external power supply for the LEDs 5V 6A. Same problem. I then injected voltage at the last strip to no avail.
I’m not sure what is causing this issue.
Any help would be appreciated.
PS, I am using arduino nano clone.
