I have built the JDM type programmer at
**broken link removed** and I am using IC-Prog with Win2000. I have downloaded and installed the Win2000 XP Drivers in the options area for the IC-Prog.
I have checked and rechecked and check once more the schematic above and it is built properly.
Everytime I try to program a 16F84A device I get the treaded "Verify Failed" error. I have verified that I have +13 Volts on MCLR and do not have a diode in backwards or the chip turned around (thanks Thunder_Scream!!)
Can someone help me please. I find this PIC programming very interesting and would love to get started. Following is my code. It is nothing more than flashing an LED (if it ever works :cry: )
"Obviously it has to do with the operating system. Correct? "
If it works on a machine under Win98, then there's an o/s issue with your machine running Win2k/XP.......you could try uninstalling the patch and reinstalling....
Other than that I dunno.......I dont particularly like the more recent Win op systems for this reason.......most of the "stuff " that I use isnt compatible/wont work........I use ME and find it more than adequate.
I've had problems also with IC-Prog (1.05A) with W2K. Programming failed randomly quite often. I searched for the fault from batteries and long connection cable between programmer and PC with no success.
Finally the problem solved when I turned Process priority one step higher. I think it's now on High.
beefer......You know your programmer works on another m/c running Win98...and you've tried it on yours with Win2k and with Win2k/98
How about just loading Win98 on and trying?
It would then make sense that there could be a problem with your machine ? Although I'd expect if you just had the single o/s on it( Win98) it ought to work 8) I know its a lotta grief but think its worth the try...
