i'm just starting with arduino. I wanted to make a padel/tennis scoreboard that i can control with a 433Mhz remote. Until now it was working fine, but that was when i was publishing the score onto a LCD display. I wanted to change the lcd display with a rgb led matrix display. But that isn't working like i thought it would work. And i don't find much information about it. On my lcd display i could simply print a variable, but on the led matrix display this doesn't seem to work. i'm using the <RGBmatrixPanel.h> library.
the part of the code that i was using when i used the lcd was looking like this
i just looked if there was i change in status of the upPlayer1 or 2 and then i could print the value on the lcd screen. But matrix.print, only work one time and then it looks like my program stops somewhere and doesn't receive any interuptions of the 433mhz triggers anymore. Is there someone who could help on the way? thx!
Can you do matrix.printing all by itself, that is just try to get some printing to the matrix going on, without all the complexities and possible errors in the rest of your code?
It certainly feels like… the problem isn’t in the code you posted, meaning that it is in the code you did not. Post.

I Noticed that when i put the matrix.begin(); line in the setup section, my program already isn't reacting on my 433mhz inputs (the led on the board isn't flashing when i push the button).
I use port 2 for this interruption, maybe this port is also used in the matrix code? but i don't find info about it
I played a bit with the testprogram of the display and, that is working. afterwards i add the code for the serial communication. But that isn't working. From the moment i put the matrix.begin() as commentary the serial communication works again. So i think something in the library of the matrix is blocking the serial communication or is there something wrong in my code?
