Hi Cris,

I changed my properties from the Interval Timer. I choose the Timeout period to "us" instead of "ms" and now my core doesn't work any more. If I change it back it works again.

I changed it to "us" because I need to astimate a frequency over an "PIO" which is round about 1.2KHz. I tried it with the "ms" Timeout period and the messurement of the frequency was not right and also the result was randome. That means that the frequency which was measured was from 700MHZ to 1.14kHz and not the 1.2kHz.

Do I need to change other setting to if I changed the Timeout period of the interval timer?

Thanks in advance for the help!
