ADC issue - holding To be honest I also found a case of CLI/SEI I hadn't removed in the Timer ISR going against theusch's recommendation - I corrected that too now and everything is working.
In fact...

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...

ADC issue - holding Thanks for the comments!
Regarding 1) the behaviour is the same even without CLI and SEI - in fact I added them just on a hunch in the last builds - now removed.
Regarding 2) am I...

O/T your language of 'origin'? I beleive you, it's far from being trivial... and I was suicidal enough not to get a textbook (I thought that since it was a minor two-point subject it was not worth the time and...

O/T your language of 'origin'? Wonderful thread guys! ...except for the fact that I'm realizing that quite a bunch of you have been programming before I was born :/

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...

Optimization flag and "relative jump to self" Damn! So stupid of me! :( I had the same problem over a year ago when using a TMS320 board in my engineering course, but too much time away from this stuff and I'm getting rusty!...

Reading vehicle RPM Got a small 72cc Honda, and as far as I know all small Hondas after 1982 (except some of the most modern ones) run mostly with AC systems, as Guillem said.
The flywheel is a four-...
