Hi, I'm trying to program a PIC16F826 with a JDM programmer ("Multi chip programmer" from http://www.talkingelectronics.com) and IC-Prog 1.05C. I always get the error message "Verify failed at address 0000h!". Anyone know what the problem can be?
You don't happen to mean 16F628 do you? Potentially lots of things at this point. Did you erase the chip first? If so, did you try doing a blank check after the erase? Did you set the proper chip type in the programming software? How about the CONFIG bits? Does your computer's serial port output a high enough voltage to put the chip into programming mode? If it's a laptop, probably not.
You don't happen to mean 16F628 do you? I ment to write PIC16F628. This is what I have selected in IC-prog as well. The chip is new and blank. I have also erased it and done a blank check to be sure. (Tried a second new chip as well.) Oscillator: Tried every option while keeping the settings below. CP: off WDT, PWRT,BODEN,LVP,CPD: off MCLR: on I'm not sure about the voltage. I have measured the MCLR pin while programming and got 11.8-12.2 volts. I'm not confindent this is accurate because my voltmeter is slow to respond to changing voltages. I'm not using a laptop.
I assume it passed the blank check then. You should probably turn ON the PWRTE, but it's not the problem. It's supposed to be 13V, so you might not be getting enough voltage to the PIC to put it into programming mode. Apparently this is a common problem with JDM type programmers. Can you try it using a different computer? Will the software let you examine the contents of the PIC after you do an erase/blankchk/program cycle? If so see if it looks like anything at all was written to the PIC.
It's supposed to be 13V, so you might not be getting enough voltage to I got a card IO card with 2 com ports. Using these ports it works fine, so it was my com ports that caused the problem. Because of some driver problems (the new ports doesn't work with totalio.sys) it still doesn't work in XP, but from Win98 I programmed the chip with no error messages. Thank you for your help.
