Inconsistant time using interupts

[Mark J]

LOL,

Sorry Darrel, I never saw your post until just now! obviously the time it took me to actually write my last post was when you were writing yours too lol...

I'm going to bench test the code to triple check its doing what it should do, and if not i'll definately give your low level interupt a try.

Thats one thing I never thought about to be honest, as I did try to get the low level interupt working when I first was playing with your includes etc, but I never got it working (the usual, download the files, stick in the project and NOT read the instructions fully! Hmmm.. the phrase 'Look before you leap' springs to mind hehe...)

Hi Mark,
Just wondering if there was any progress?

Tnx,

Hi Sneaky,

sorry its taken a while to reply, but touch wood, it seems to be running ok at the mo! I removed all the PWM calls from the interupt and put them in the main loop and it seems to be working as it should.

When I get the project finally finished, i'll probably have a play by making the USB interupts low priority like Darrel mentioned previously in the thread.
If I do and its still fine, i'll pop a reply to let everyone know etc.

(been having probs hardware side dropping 24v dc to 12v without either having to use a huge heatsink etc, as everything ive tried so far keeps popping lol, but will be trying a step down regulator as soon as funds allow as it needs a few other parts to go with it and a redesign of the PCB, then etch etc etc.)
