First Programming - Victor/PWM help

I couldn't get that victor working on PWM 3 or PWM 1 again, so I flipped the PWMs for the right and left side. Then, PWM 3 (which was now on the front right motor) now started to work.

So I changed the PWMs to use 3,4,5,6 to see if it was a PWM Channel issue, but then none of them worked (and they still don't).

In my experience, if only one port is working or if you're having port issues, it's got something to do with the Digital Sidecar. My team had a similar issue, and it turned out to be that the DSC wasn't getting enough power.

So, basic troubleshooting for that would be remove the ribbon cable that connects the Digital Sidecar to the Digital Breakout, and check if all 3 lights are lit (BAT 5V 6V) if they're still lit, then that means you've got good power. If one of them isn't lit, make sure that your DSC is connected correctly to the Power Distribution board as seen here.

That's what I'd start with. Hope it helps
