Hi Henrik,
thanks for the info (& the link to your thread - I'll read it tonight as it's not exactly a quick 'snappy read'!) - just to clarify, I'm using scalerobotic's code ....so anything declared as ASM, PBP etc...at this stage of my 'pic programming for dummies' learning curve.....blissfully washes over me! (in my naive programming world, I'm still convinced the earth is still flat & if you sail towards the horizon, you will fall off over the end)
I've already picked up that when using ASM interrupts, that you have to be careful what you get up to in the interrupt handler (ie get in, get out asap - handle the stuff in your main code), but I've no intention of doing much in there (bar the odd port toggle to assist with scope observations!)
Re generating sine waves - I've actually a couple of AD9835 ICs winging their way over the North Atlantic to me as I type - they seem to be a rather quite serious way of generating sine waves! (but while waiting I thought I'd have a dabble with this PWM method, just to start getting up to speed in the black art of Sinewaveology!)
