Hi,
I just finished of with my development board. I'm using Proton 7 for compiling and the problem is that the led matrix I've connected with the zif adapter to toggle isn't working. I checked all the points of testing and it's working fine. I tried my chip on my friend's db and the led matrix is toggling up. Can anyone help me please?
 

Hi,

You need to show the circuit diagram and your program code.
 

there might be some error in your board that probability is higher and there may be internal compiler errors also
