PWM prescaler.

Post by janjoh »

Hello!

As i understand that timers are not yet supported I guess that this is a non-starter.

But can I change the prescaler? I would like a 21-30kHz PWM base as a control module expects this frequency.

Currently PWM runs in default mode at 4 MHz. There is a possibility to turn it into 31.25kHz mode. We have not yet implemented this. Note that this will affect all four PWM ports.

Please explain us why do you need it. We need it to correctly planify and schedule our work.

Was planning to use Zuno to talk to a ventilation controller.

But, I still need standard "high speed PWM" as well.

I'll just drop a tiny between the zuno and the controller I guess.
