To take this to the logical conclusion, it is the puff of smoke that provides the operating characteristics of the device. No more internal smoke, no operation. wrote: >Message: 1 > Date: Mon, 26 May 2003 09:11:33 +0300 (EEST) > From: Vasile Surducan <> >Subject: Re: Re: PIC16F84A , JDM and IC-Prog 1.05A problem.... > > >On Sat, 24 May 2003, John Remington wrote: > >>>>I also get verify errors after I let the smoke out of the chip :^ >>>> >>>> >>>?!?!

oh, wait, my bad . . . if you are getting a good "build" then the IDE is set up correctly. In the ICProg, take settings, hardware settings, and make sure you've selected JDProgrammer, the correct com port, direct I/O interface, no radio boxes checked under communication, and a I/O delay of at least 4 (mine is set to 10). At least that works for me. else go here for help >>> http://tutor.al-williams.com/pic-download.html --- John Remington <> wrote: > > > > > > I also use MPLab,maybe i do have the same prob.

I don't know what "let the smoke out of the chip" means... okay, well at all electronic factories there are little gremlins who's only job in life is to put a little tiny puff of smoke in each device. If you let that puff of smoke out the device fails to operate. Bigger devices get more smoke, like transformers, etc. Sometimes, as with PIC chips, that puff of smoke is pretty hard to see. With other devices it's easier to spot . . . try putting a 12v car battery or so on a 1 ohm 1/4 watt resistor and that puff of smoke emerges . . . __________________________________

what program are you using to write your code? I know that when using the MPLabs IDE I have to be very careful that the IDE is set up for the specific chip, else on load (using 1.05) I get verify errors. I also get verify errors after I let the smoke out of the chip :^ --- Vasile Surducan <> wrote: > > AFIK IC-prog 1.05A is a beta version.

AFIK IC-prog 1.05A is a beta version. Ask better the creator: "Bonny Gijzen" <> However, test if this is happening every time you are trying to program the PIC, or just sometime, test the pin connections and if no success, switch back to icprog 104. And test also if settings->option->misc->enable Vcc control for JDM is disabled and settings->hardware->io_delay is greater than 4 for direct IO interface.

Hi, i have a serious problem with IC-Prog 1.05A. When i try to programm a PIC16F84A (4Mhz) with the JDM programmer i always get a veryfy error at 0x00 . PIC12F629 are working fine and Pony-Prog with PIC16f84A also is doing fine,but Pony-Prog tells me that i have 2K flash what is wrong. Does anyone know this problem and how to solve it?
