Content mismatch when using serial but nor on ISP
So unless you have the V model, you are limited to 4.5-5.5v?   Yes, Curt. Bugger huh ?   I once needed a Mega2560 to run from a LiPo, and since all AVR-types I used so...

Content mismatch when using serial but nor on ISP
I am running W10 Home v1803 on a 12 core Intel I9-7920X @ 2.9GHz with 64GB ram, but I am pretty sure avrdude wouldn't use all the cores anyway, so who knows. I really can't...

Higher Voltage of Low-Logic Level and Unclean Output from ATTiny2313
My guess: OP uses fastPWM mode. He'd better use Phase and Freq correct PWM instead. PWM frequency drops to half but the good news is that 0% PWM == LEDs OFF. This is described in...
