Hi community! 
Ok, I've been working on P10 panels lately, would love to use a keypad to set the display after going through all the settings I made (speed, language of display, ...)
Everything was running pretty fine before adding the DMD code, once I confirm and click on "#" the message will start scrolling then I can't update it or use both the LCD and the keypad 
I tried to use the goto but I faced the same problem 
Thanks for you help.
