Hello,
i m new to programming PIC microcontrollers.....recently i built the JDM programmer and used IC prog to program the PIC16F84.......but it showed "verify failed at address 0000h".......what might be the problem.....plz help me....

Did your reset the fuses?
What voltages do you have at the PIC programming socket for clock, data, and MCLR?
JDMs often fail on modern PCs because few modern PCs actually generate RS232 voltages off their serial ports. JDM programmers depend on that
-12V to 12V swing to operate properly.
Take a read around my Trivial PIC programmer site for insight into the voltage, testing, and which part to choose issue.
I would suggest ditching the 16F84, upgrading to a 16F88, 16F648A, or 16F628A and building a simple parallel port programmer.
Good luck,
BAJ
