Timers not working ??

[aknik]

Hi,
I need to modulate the signal with a timer, but timer seems not usuable with your code, at leas it seems to me. :-)
#include <Ticker.h>
tickerSetLow.attach_ms(100, DcfOut );
This does not works ! No error, but do nothing at all !!!
I need a timer for doing a routine each 100 milli secons.

Thanks again for your help !!!
