Guest janos Posted January 7, 2004 Report Share Posted January 7, 2004 Hi all,i've built a JDM programmer about one year ago and used it once to program(with icprog) an IR reciever on a pic 16f84A and it workedBut now, i need to program two other pics (16f84A) using icprog and i can't program themicprog reads all 3FFFh but can't program it :"error at adress 0000h"i've tried to change io_delays but it doesn't seem to be usefuli've watched many forums about problems with the JDM and tried a few things but it still fail. i haven't modified the JDM itself because i'm sure it is a software problem.in the windows serial port options , do i have to enable hardware flow control or notmy settings are : 9600bauds - no parity - 8 bits - 1 stop bit - no flow controli've tried one 3 pcs (including the one i used one year ago) and it doesn't workcan someone help me?sorry for my english, it sucks because i'm french Quote Link to comment Share on other sites More sharing options...

Wilba Posted January 8, 2004 Report Share Posted January 8, 2004 This is how I got my JDM programmer (for PIC16F84s) going (scroll down to section with orange background): http://www.talkingelectronics.com/FreeProjects/MultiChipPgmr/MultiChipPgmr-P3.htmlYou don't need to change serial port settings in Device Manager. JDM doesn't work like that - it's not doing RS232 communications.Also: just because the hardware worked a year ago is no guarantee there's not a problem now. Maybe there's a broken track or bad solder joint. Use the JDM troubleshooting guide to verify programming voltages and IC-Prog configuration.
