How to Increase and decrease frequency by using button sw2 and sw3 in s32k144evb?

Hi,

I try write a program in design studio which generate digital signal about 1000HZ frequency (square signal) using pin with function gpio. Next I have to read this signal by using ftm. And finally I have to enable change frequency by using sw2 and sw3 buttons by 100HZ ( for example: If I once pushed sw2 button frequency should be 1100 HZ and so on. This button should enable increase and decrease frequency.) Could you help and correct my mistake? I don't know what is wrong with this code. I will be very grateful.

Regards

Hi@miketorres

Sorry for the late reply.

I wrote a example project for you, and it works fine on my side.

BR!

Jim,
