Welcome to the world of PIC. Sadly you are one of the many victims of the obsolete information on the internet regarding how to begin with PIC programming. Never mind, you are lucky to join PIClist. Want to be faster? Want to fix the problems once and for all? First thing to do is to dump the JDM. Then put the 16F84A inside the drawers. Buy or make a proper programmer like Wisp628 or EasyISP. Then choose a chip supported by the programmer. Chips like 12F675/16F684/688 are good options. ----- Original Message ----- From: "Dionis Teshler" Newsgroups: gmane.comp.hardware.microcontrollers.pic Sent: Tuesday, August 16, 2005 8:52 PM Subject: [PIC] Programmer doesn't burn all of the program Hello all, I am pretty new to microchip programming, so forgive me for maybe being kind of slow. I am on JDM with all of the options inside "communication" unchecked. I am programming on win XP and using PIC 16F84A with the icprog XP driver. How can I fix this problem? __________________________________________________ Do You Yahoo!? Tired of spam? Yahoo!
