Hi,
I am using the following code (see in attachment), to perform 40 KHz frequency generation on my M0PRO, based on PWM timers. I can adjust frequency and duty cycle thanks to dedicated values in registers. All is OK !
I would now generate BFSK starting on this code, by changing the frequency value in the register. That's easy, OK.
The point is that I don't see how to manage the time duration of each frequency burst, i.e how to start and stop each frequency burst, how to start / stop relevant timers ?
Does somebody can help ?
Many thanks
