Hi chaps

Does this group also include the Raspberry rp2040/rp2350 as well? I'm
in need of resources or the knowledge of how to program the PWMs on the
rp2040. If not, are there any online resource I can consult. 

The rp2040 datasheets are instrutable on the subject of the PWMs. I can
easily blink an ordinary LED, likewise for a RGB LED via three GPIO
pins, but for doing cool tricks like fading/brightening the separate
RGB components on a RGB LED it's beyond me, I think PWMs are needed for
this but all I could find was micropython stuff and that works but I'd
like to know how to do it baremetal with ARM thumb assembly. 

Many thanks,
Alex
