ADC issue - holding
So finally I'm getting to the bottom of this! I started by removing everything from the code except for the timer and ADC initialization and ISRs. Everything worked fine. I've...

ADC issue - holding
I'll copy the project and remove all the code not related to the timer/adc systems - then I'll give it a try on the dev board to see what happens - unfortunately no access to the...

Here's the missing info... excuse my brevity in the first post. ISR(TIMER1_COMPA_vect) { //Should use timer in WGM4 mode. will give an interrupt every 5000 clock //cycles...

Extreme insulation resistance
Hi Peter, I hope I can explain this somewhat more clearly. The insulation resistance test is specified to be done by a tester that outputs 500V DC. I have manual testers which...
