Is there any support for MCPWM in Your?

Not yet. We use the ledc for PWM.

I think it should be straight-forward to expose them, but so far we didn't need them.

And browsing through the documentation, is is quite configurable.

While straight-forward, it might take a bit of time to expose it.
smolesen 10/22/2022 06:32 AMHi, I can find lots of "hits" for MAX PWM Frequency, but I want Sub-Hz values (0.1 - 0.5Hz). Using this commonly found technique: int PWM_FREQUENCY = 1; // this variable is used to define the time period int PWM_CHANNEL = 0; // this variable is used to select the channel number int PWM_RESOUTION = 8; // this will define the resolutio...
Ok, just had a need for making a PWM with a low freq, and saw this post

I see.
I would probably just run a loop with sleeps in a task, but that wouldn't be as precise as the hardware.

I vote for MCPWM support too, when you have the time
