Post by thread:COM84 and NT4.

I guess from the lack of replies that none of you guys out there are using NT4 and COM84 type programmers. Looks like I will be writing a blower after all (downer). Does anyone know where I could find PD source code (DOS, WIN311 - C, ASM, Pascal are all fine) to kick start me, once done I will make the blower PD and put on to a WEB page somewhere (just in case someone moves to NT4 with COM84 hardware).

Paul, There has been quite a bit of discussion on the list about driving simple parallel/serial port programmers from windows. The conclusion seemed to be that although it can be done, but that there will always be an uncertainty in the timing of the programming pulses. Jim is (or was) giving away the hex code to turn a parallel port style (e.g.Tait) programmer into a serialy driven one using a 16F84, this would seem to be a far more reliable way to go, although obviously not as convenient as COM84 from the point of view of supplys etc. Regards Mike Rigby-Jones > {Original Message removed}

With 16 bit Windows (3.x/Win95/Win98) it's not too bad getting timing down to 1mS, but with 32 bit Win NT it seems MUCH! harder. I'm presently considering using Timer3 to generate the timing delay, I currently have it working from DOS, next I will try it under Windows 95. Is their anyone on the list who knows is you could use this under NT?. -- Nigel. /--------------------------------------------------------------\ | Nigel Goodwin | Internet : nigelgKILLspamlpilsley.demon.co.uk | | Lower Pilsley | Web Page : http://www.lpilsley.demon.co.uk | | Chesterfield | Official site for Shin Ki Ju Jitsu | | England | | \--------------------------------------------------------------/
