C3 support (is buggy) #4
Description
C3 support is added in esp32c3 branch.
There was a problem with watchdog, so tight loop break out was added, not sure it was good idea.
Something is wrong with offset calculation still:
[2025-12-21 16:01:49.952389] I (12037) dtr: Offset: [26465357 - 26517335 = -51978] avg 26491346 (662283.650 us), loop: avg=24.691, min=1, max=75
Normally it should be small and positive. Possible reasons: GPTimer we use is used by something else, GPTimer's counter is 64 bits while MCPWM was 16 bits, maybe some type conversion bug.
To be investigated.
