Code programming error is MELabs way of saying somthing is wrong with the target - usually no Vdd or low Vpp but it could be anything, its a pretty generic error message. I believe it specifically means that the programmer couldn't gain control of the PIC but it runs in my mind it also happens on a validation error in some circumstances. Check to make sure you've got voltage to the chip - I've seen it there (programmer is powered, icsp target is not).

Bill, As it turns out, I was just working on a 16F819 project. So I tried my melabs serial programmer a couple of minutes ago and it worked fine. I have the 8-40 ZIF adapter and nothing else is required. Not true when I was using a 16F57 - I had to buy a special dongle for that chip. FWIW, I have never been able to get the programming software to run on Windows XP. I know it should but it doesn't work for me. I run it on my old Win98 SE machine - works fine.

Richard, good to hear from again, according to the melab serial programmer help section all F81s, F87As, and f87/88s should have Portb3 grounded. I've recently bought a Melab serial programmer and had to use my old 22pin zif with it. I can't tell if the Port3 is grounded or not. I've ordered a 8-40 pin zif and maybe the port3 is ground on it. Maybe, mabe not. I'll try it in circuit with the pin grounded and see what happens. thanks bill ----- Original Message ----- From: "rtstofer" <rstofer@rsto...> To: <piclist@picl...> Sent: Sunday, May 15, 2005 3:43 PM Subject: [piclist] Re: cc5x syntex config symbols > > Bill, > > Are you getting bit by the Low Voltage Programming issue?

Bill, Are you getting bit by the Low Voltage Programming issue? Pin 9 of the chip must be grounded during programming and some programmers are too old to know about such modern conveniences. In fact, I gave up on all my other programmers and bought a PicStart PLUS figuring that if anybody knows how to program these things, it is Microchip.

Thanks Mike, I don't think its the com port(I've been programming other chips along with trying to program the 819s. Its odd the programmer software problem would be in both programmer. I'll check with Melabs support and see. thanks bill ----- Original Message ----- From: "upand_at_them" <upand_at_them@upan...> To: <piclist@picl...> Sent: Sunday, May 15, 2005 2:38 PM Subject: [piclist] Re: cc5x syntex config symbols > Check to make sure you don't have the COM port open from another > application.

Check to make sure you don't have the COM port open from another application. Close all apps except the programmer software. You might even have to reboot. Failing that, you've got a problem with the programmer software or hardware. I just successfully programmed a 16F819 with that config.

Mike, I did what you suggested the command lines: #define CP_off |= 0x3F30 #pragma config CP_off,PWRTE=on,WDTE=off,FOSC=HS,BODEN=on And it worked great on Pic 84A. Now I'm trying to set the config on Pic819s. Using the same format along with others. I not having any luck. Looking at the pages 27-34 819 datasheet it seems to me this would be handled by the programmer. I'm using epic serial programmer and older melab programmer. Both programmers worked well with other chips. Whenever I programmed the chip I get error "Code programming error at 0000". What is needed here? thanks bill ----- Original Message ----- From: "Bill Davis" <wdavis@wdav...> To: <piclist@picl...> Sent: Friday, May 13, 2005 4:22 PM Subject: Re: [piclist] Re: cc5x syntex config symbols > thanks > bill > ----- Original Message ----- > From: "upand_at_them" <upand_at_them@upan...> > To: <piclist@picl...> > Sent: Friday, May 13, 2005 4:02 PM > Subject: [piclist] Re: cc5x syntex config symbols > > #define CP_off |= 0x3F30 > > #pragma config CP_off,PWRTE=on,WDTE=off,FOSC=HS,BODEN=on > > > > Mike > > > > > > --- In piclist@picl..., "Bill Davis" <wdavis@t...> wrote: > > > Thanks for the reply, I've looked at page 46 and page 51.
