I'd actually ruled out using a resister type voltage devider for the reason that it draws curent from the source your measuring... I had thaught of an opamp or another type of amplifier...

Then use higher value resistors (Mohms) and a suitable opamp as an unity gain buffer, like the LMC662 series (rail to rail).

Also, I think the PBP way of handling interupts is stupid... you should be allowed to write interupt handlers in PB without PBP inserting all that extra code...

Read my post again. Answer is DT-INTS. It has nothing to do with PBP interrupts. Credits go to Darrel Taylor for his great contribution. Look also his site www.pbpgroup.com for the software.

P.S. I still have that old ZX Spectrum and Zeus assembler. What days was those...
