Hallo
Ich habe ein Problem mit meinem 8x8 Matrix Display immer wen ich auf Programm testen gehe bekomme ich eine fehler Maldung immer ihr FrequencyTimer2::disable(); ich weis nicht was ich da tun muss
Der ganze Programmcode ist unten
Danke im Voraus 
/*
* Show messages on an 8x8 led matrix,
* scrolling from right to left.
*
* Uses FrequencyTimer2 library to
* constantly run an interrupt routine
* at a specified frequency. This
* refreshes the display without the
* main loop having to do anything.
