Ahh yeah, excellent work on that EasyB! I’ve used the CN5710’s with RampingIOS as well, but with an attiny412 (custom 5-amp linear driver for the D1S and also on my OL7 and OL8 contest builds).
Same basic change is needed to TCCR0B. In int main() you’ll find:
// Set timer to do PWM for correct output pin and set prescaler timing
TCCR0B = 0x01; // pre-scaler for timer (1 => 1, 2 => 8, 3 => 64...)
You’ll want to change that to this for the 8x prescaler on the PWMs
// Set timer to do PWM for correct output pin and set prescaler timing
TCCR0B = 0x02; // pre-scaler for timer (1 => 1, 2 => 8, 3 => 64...)
