I built a programmer according this cheme:
**broken link removed**
it's David Tait's programmer modified a bit by Bob Blick.
I'm using WinPic sofware and PiC16F84A-04 controller.
I choose in Interface menu 7407(driver)+pnp transistor
When i press initialize message "Could not initialize programmer" comes
What's the problem.
When i check Vpp,a 13 volt appear between 4 and 5 legs of the chip
When i check Vdd a led turns on and off
Also Clock and Data (to PC) affects on the led.
I use SMPORT driver on WinXP SP/2 workstation
1.How WinPic knows that interface could not be initialized,it wait message from microcontroller?
