Sorry I'm a bit slower to respond....I have a *LOT* going on :) In fact, I was about to dive back into another project, but remembered this! Waiting probably helped,...

Ok, for sure, pins 2, 3, 4, 5, 10, 11, 12, and 13 should be completely unaffected...(I'll double check my timer code though) those are done on the timer hardware...

Ok....I see an issue...PWM_DIS is write only (duh) yet I'm performing an & operation to disable....Which is why you don't want to use the code changes recommended above :) Writing...

Good catch…yeah, no one wants more confusion! That data sheet is confusing enough as it is! ;) I will see if I can get things setup tomorrow. I did something...

Ok, I committed in place...poor form, but I'm going to go to bed. I'm exhausted after yesterday, and had planned on being asleep 2 hours ago! So technically the commit...

You are in so much luck....I'm not sure what the seeduino xiao is, (duh, its in your title) but I'm still not sure how much it is like the DUE/SAM8x3e....

So, I did just have a look at the data sheet for the SAMD21G18. Sorry, my fork will definatly not work. The M0 and M3 from atmel are just too...

There are actually other instances of reading a write-only register beyond that one. Those are some of the changes in my local copy that I didn’t want to lose. I...

Hmmm, I’ve definitely run faster than 8khz. I suspect you’ve got more interrupts running on the processor. That’s not to say that this code is behaving. I documented in another...
