Hi Rob,
can't get past the dreaded "sync" error.
I'm recalling that is the error you sometimes get from the Arduino IDE when you you try to upload?
It's been awhile since I used it last, so I am unsure what might be the problem there for you on that one, sorry.
Hopefully you have been able to upload now?
For that matter just write 32 every time but record that the value was wrong.
Yes, I think I will for a test, just set bit 5 of TCCR3A in the function I call every 100mSec after checking if it was still set.
If it was not set, I will raise a flag and look at ways to used that to check what caused it to be cleared.
smells of memory leaks
Yes, a stinky foulish pukey leak, it could be.
I will make the change shortly and let it run overnight and see what happens by morning.
Paul
