Very Simple ICSP Programmer

[bearpawz]

Well, this is a "development" machine I use so not much of anything running anywhere... using windows 98SE..

You know, I really wish I could find the old "Kit96" progrrammer. I had that once and it got lost when I moved... but never had any problems with it and it was only about $15.00. If anyone has one laying around they dont use, or for that matter has the schematic and PCB files (I beleive the kit that you put together came with a PCB layout in the literature).

I sure miss that programmer.

How about the cable between the PC and the programmer? If it's a serial cable, it isn't a crossover cable is it? How about the ground pin (9 or 5, can't remember which), is it connected? With mine, I've got continuity between the ground on the Warp13 and the case of the PC. I've heard where some laptop users have problems because the ground in the cable isn't connected (myself included!). I had to blob-solder a jumper to the hood of the cable back in the day to get it to work.

Not Enough? Just search for P16PRO40

Enjoy!

Have you tried another uPic.. Say a 16F628 or 16F88?

This programmer works just not on chips ending in 'A' or when connected to laptop serial ports.

Hey Squibcakes-

I'm using your program for development using ICSP with '873A, '876A, '877A - and ICPROG, no problem, works every time

Are you saying that you have come across some problems with -A suffix PIC's and your programmer?

regards

Angus

Hi Angus,

Yep. I don't use too many chips so I can't say this effects all chips ending in 'A'. I've tested the 84A, 628A chips and they only programmed the first time for me. Subsequent writes failed.

Not that it matters I mostly use the F88 these day's with no problems.

I'm glad it works for you and your happy. For a cheap and dirty programmer it does the job very well. Anyone else wanting a more reliable solution should buy a specialist programmer and pay a handsome sum for it. Mr_e will gladly take your money!

Have you tried using Winpic800 (Free prog software)? Its a lot faster at programming than IC-Prog.

Cheers

Hi all,

Acircuit or assembled piece doen't work, the solution need not be hardware and we need not rush tp spend and order another readymade board-- If that does't work shall we run for a third item?

Just cool down and think logically we can resolve. afterall intermittent failure may be due to improper configuration of the hardware w.r.t O/S (like win98,winXP)

i quote a comment of a programmer designer Mr FENG (FENG3 programmer 5.3 ver8). he once idcated he was still using RCD programmer. It proves Hardware / sofware can be maintained and debugged than rushing for replacements.

See the requiremets of a particular chip are met as per programming considerations, while programming a chip. (sometimes one of the RA pins is tobe pulled down)

How i can to do this ???

[turman]

Hello everybody, I am new in this forum. The last week i programmed one 16f88, with my GTP USB LITE . I was my first time with this pic. I programed it with internal oscilator 8 MHz , and PB7 and PB6 , put high and low intermittently.

The problem was when i try to programmer other time. This fail, because the 16f88 enter in oscilation mode before programming mode.

How i can to resolve this ????

Thanks !

Enable Vpp first, then Vdd on your programmer.
