DueTimer

Hello

I’ve downloaded the DueTimer https://github.com/ivanseidel/DueTimer. The Library works on the arduino Due but my Problem is the message

sketch\ALADIN_V2_0.ino.cpp.o: In function `setup':

H:\Arduino\ALADIN_AW21_126\V2.0\ALADIN_V2_0/ALADIN_V2_0.ino:21: undefined reference to `DueTimer::attachInterrupt(void (*)())'

H:\Arduino\ALADIN_AW21_126\V2.0\ALADIN_V2_0/ALADIN_V2_0.ino:21: undefined reference to `DueTimer::start(long)'

H:\Arduino\ALADIN_AW21_126\V2.0\ALADIN_V2_0/ALADIN_V2_0.ino:23: undefined reference to `Timer1'

collect2.exe: error: ld returned 1 exit status

Multiple libraries were found for "DueTimer.h"
 Used: C:\Program Files (x86)\Arduino\libraries\DueTimer
 Not used: C:\Users\reka\Documents\Arduino\libraries\DueTimer-master
exit status 1
Error compiling for board Arduino Due (Programming Port).

and this is a part of my sketch

Timer1.attachInterrupt(wave).start(1000);

can anyone help me? Thanks :slight_smile:

with Kind regards
