The schematic, photos and PCB have been developed by PICMASTERS based on
some valuable works done before.
This programmer supports pic10F, 12F, 16C, 16F, 18F,24Cxx Eeprom.
Unfortunately, it works with only Winpic800 v.355.
We have succesfully tried it with some pics; PIC18F252, 18F2455, 18F2550,
18F2520, 16F84, 16F628 and 24C32 eeprom.
The best and fastest method of pic programming.
All you need (hex file, winpic800, schematic, PCB board in ARES)
are included.
You must program pic18F2550 with hex file by a classical programmer.
Just leave a good fedback for us.

thanks... penticon2003@yahoo.com
Can i ask whats the purpose of 18f2550(replacement 18f4455) in this programmer? which is there is already a 40 pin ZIF socket for programming, i use 16f628. Confusing.. I building my new version of GTP programmer.. so i need some help..

pleas i want to ask about the cable in the left side in the picture
what it's job and where it's connected
i'am waiting for your replay
and thank you again
gud luck ..
Send it to me at: imalu@telecentro.com.ar
Thank you.
Dear Sir,
I just built "GTP USB PIC PROGRAMMER".
At first start-up surprise .... (pinul9-ULN2003 = not connected). Design mistake.
Step two: driver GRABADOR TODOPIC-USB is not recognized by Windows XP Professional.
What to do?
You ever work?
There is another design mistake, incorrect component values?
There is another USB driver?
Thank you.
Happy Birthday!

Lamentable!!
I successfully built this programmer but wondering why I can't program 18F2455? It can't even identify this chip!
Tested on PIC16F84A,16F628A,18F877, 16F76, 18F4550, 18F/LF452 but everytime I tried working with 18F2455 DEVICE: UNKNOWN is the result...:(
so good!!!
The firmware that is loaded in the 18F2550 "GTP_USB.hex." Is it right?
"GTP-USB-MAIN-PCB.LYT" opens with Proteus?
Thank you very much,
Claudio.
thx already
Thanks !
But keep up the good work.
I assume there must be some kind of ripple or pattern generated on the RA0-3 pins.
Any ideas?
thanks for that great programmer I'm in the process of making one of these and yours seams to me very nice there is one problem however my English isn't so good so if you can write the parts names i couldn't find any "tantalum" cap in the schematic so i hop if you can help at this and make a text list ??
I have the same problem youve got , did you manage to sort it out yet?? Please let me know.
Man that programmer of Frans Schreuder looks like Chinese to me. Building it will be piece of cake, but all that setups makes me deurmekaar. Can I just program the IC in the programmer with a hex file ( which one of the hunderd files ?) , without the bootloader ?? How did you go about it?? Would like to hear from you.
Then I install all the USB Lib files to PC (http://sourceforge.net/projects/libusb-win32/files/) and then install the Programming Software.
In selecting the files needed to be installed, choose the most recently released version.
That's all then you can start programming target PICs.
someone know if work on windows 7?
thank's all
I would like to know how does this programmer works or From usb how does data streamed into this progarmmer board and how does this programmer programs the PIC............
Thanks in advance sir...............and gr8 work
