Hello all,

I'm trying to get a pwm signal on an arbitrary output port, but currently, it seems that I can only get a pwm signal on ports pb19-pb22 for channels 0-3. I've tried playing with an example project on pwm from atmel to no avail. Is it even possible to get a pwm signal from an arbitrary port (say PB12 or PA17 or something) ?

I appreciate your help!

That's really not how the pin muxing works, you have a small list of options, not a cross-bar switch that gates anything to anything.

You can individually switch

PWM0 PB19 or PB27
PWM1 PB20 or PB28
PWM2 PB21 or PB29
PWM3 PB22 or PB30
