Change tick value of timer compare event

I found my mistake. It was somewhere completly different and did had nothing to do with the code I posted. The code above works fine, the last three lines where the nwe adresses are set and the ppi channel is assigned again aren't even necessary.

Sorry for the wrong thought question. Thank you for your help.

I have already tried that. Nothing changes. The Interrupt-Function also doesn't get called after the "reinitialization" of the timer.

In nrf_drv_timer_extended_compare(..) you have disabled interrupt (set it to 'false'),try to enable interrupt and see if it changes anything.

Yes I have connected the saadc end event and the start task over ppi. Just checked the newTickValue while debugging, seems to be correct. Frequency of the timer is 16MHz.

ah right. I have never used that driver. nrf_drv_timer_enable triggers start task for the timer. do you start saadc after each sampling? (probably by ppi). You sure you provide correct newTickValue? What is the timer frequency?

But I don't need to start the timer the first time either. However I tried using the nrf_drv_timer_resume() function know but that changes nothing.

I think you forgot to start timer after re-enabling it.
