I'm quite new with DZ60 and I need to measure the frequency of a 50 to 200 kHz square wave signal.
My first idea was to use TPM2CH0, and to mesure the number of clock cycles between 2 rising edges
of my signal. It works but there are a lot of interrupts (at each rising edge) and it slows down significantely
My second idea is to measure the number of pulses in a 250 ms interval.
but I'm unable to configure the TPM2 timer in this way ?
For instance, I've tried to configure :
TPM2SC = 0x18;
TPM2C0SC = 0x04;
But the TPM2C0V counter doesn't increase ?
Could someone indicates me if it's possible to count automatiquely incomming pulses ?
What should I program for these 2 configuration registers ?
Thank you very much for your help
