So I built a PIC programmer for 16f84a. My friend tried it on his computer and it worked. I tried it on mine and it didn't. So I thought it's the OS, so I tried it on my other computer (which had win 7 beta installed as my friend's computer). Didn't work there as well. I've tried it with WinPic800, ICProg, PonyProg and there is always a problem. In ICProg i usually got the error "verify failed at address 0000h" (using windows API that is; with direct i/o "privileged instuction"). After checking the use win 2000/XP drivers I get "verify failed at 000xh. x stands for the number of the code part preceding the one where I wrote something. ex. 0000 0000 0000 0100 in this case it would be "0003h"
On my friend's computer everything worked great, even the clock function (lighting a led on the circuit). I'd be really pleased to see only that work. In WinPic800 when i click Read DEV ID-REV I get Detected -> UNKNOWN, DEV ID -> 0x0000. When I click Hardware Test I get ERROR -> Hardware is not responding. When measuring the programmer board circuit near the COM port connection pins I get a reading somewhere between 3,5-3,9 V.
I've tried nearly all possible setups with all programs, gotten rid of spoolsv.exe running, tried installing all kindsa drivers for COM port etc etc.
And still it doesn't work. Any idea why? Thanks in advance for the help.
