I have been working with P10 modules for a while now, using the DMD library and everything was working perfectly.
After about a week, I tried to program another P10 module using the same exact code I used for the first one, but after the code uploads nothing is displaying on the P10 modules.
I've tried to change the module itself to another one I have, change the microcontroller (Arduino Uno) and even the connector. I'm also using a 5V, 10A power supply.
I'm suspecting that the problem is with the program, maybe the library or something.
Any suggestions to help please?
