This work includes, GTP USB (not plus or lite) .

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.

Step 1: circuit scheamatic

circuit schematic. You can see the type and value of the companents.
Es muy parecido a un dise&ntilde;o que esta en forosdeelectronica.com<br>y el que lo dise&ntilde;o es de cheyo28<br>http://www.forosdeelectronica.com/members/cheyo28/
<p>para<br>programar un pic especifico todos los programadores que se utilice con ese pic tendr&aacute;<br>dise&ntilde;os parecidos por la sencilla raz&oacute;n de que ese pic se programa igual en<br>todos los programadores sus respectivas tensiones en sus pines deben coincidir<br>para la programaci&oacute;n y por ende los circuitos ser&aacute;n similares esto se cumplir&aacute;<br>siempre que la programaci&oacute;n sea por el mismo puerto igual en todos ellos</p>
<p>pls where is the hex file </p>
My country is Bangladesh what can i caret pay pal account. <br> uddin.shofi@yahoo.com

Can not open the file.. tried everything but no joy... can any one supply in eagle cad file please???
Honestly one of the best looking PCBs I've seen. The whole project is just really well built &amp; aesthetically pleasing to look at. This is something I'd want to always have out on the workbench so people can ask about. Job well done. =]
can anyone tell me list of the materials required
plz giveme programing hex <br>thanks... penticon2003@yahoo.com
Hi everyone! <br>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..

What is the value of the diodes without reference? Because there is a tantalum capacitor in PCB layout and there? Works on any PC configuration? What cable did you use and what is the one COM port? Congratulations on the project hope to answer me ...
Hi very nice <br>pleas i want to ask about the cable in the left side in the picture <br>what it's job and where it's connected <br>i'am waiting for your replay <br>and thank you again
А кто подскажет , где взять 13,5 вольт? Заранее спасибо.
Where is the all_of_thedocumantries.rar file? All I get is a *.tmp file.
rename the file with (.tmp) = (.rar) <br><br>gud luck ..
Hello! Could someone please tell me what the firmware that works with this programmer? For whoever got from this page will not work.<br>Send it to me at: imalu@telecentro.com.ar<br>Thank you.<br>
Excelente project. I will build it, and post my comments after.
Hi!<br>Dear Sir,<br>I just built &quot;GTP USB PIC PROGRAMMER&quot;.<br>At first start-up surprise .... (pinul9-ULN2003 = not connected). Design mistake.<br>Step two: driver GRABADOR TODOPIC-USB is not recognized by Windows XP Professional.<br>What to do?<br>You ever work?<br>There is another design mistake, incorrect component values​​?<br>There is another USB driver?<br>Thank you.<br>Happy Birthday!<br>D. Sandu
Hola! Lamentablemente reitero, ahora en espa&ntilde;ol, el programa HEX que obtuve NO FUNCIONA!!!. No se cual es la trampa. Habr&aacute; que pagar para obtenerlo ??? Una l&aacute;stima, realiz&eacute; un gasto considerable y una gran p&eacute;rdida de tiempo. Recomiendo constru&iacute;r el GPIC USB en SITIONICA. Es ARGENTINO y funciona, no se enga&ntilde;a a nadie y si tienes un problema o duda el autor te responde inmediatamente, como debe ser.<br>Lamentable!!
nice work<br>
Hi,<br><br>I successfully built this programmer but wondering why I can't program 18F2455? It can't even identify this chip!<br><br>Tested on PIC16F84A,16F628A,18F877, 16F76, 18F4550, 18F/LF452 but everytime I tried working with 18F2455 DEVICE: UNKNOWN is the result...:(
since you did it, which is nice 4 u, now i kindly request you 2 pliz post the componets list. Ill be glad thanks nys time ;-)
Thanks!!!<br><br>so good!!!
Hello! I built this programmer, but not working. When connected to my laptop with Win XP or Win 7 USB ports do not recognize.<br>The firmware that is loaded in the 18F2550 &quot;GTP_USB.hex.&quot; Is it right?<br>&quot;GTP-USB-MAIN-PCB.LYT&quot; opens with Proteus?<br>Thank you very much,<br>Claudio.
in the schematic there are two diodes without any name or values, 8 1n4148 but dunno what are two diodes near the zif board connection...<br>thx already
please which software do you use?<br>
Does anyone has got a component-list of this project?
Hello guys i am beginner Engineering student, can someone tell me that either it works fine on PIC18f4520 or not because i have an assignment of building the kit circuit and i want to build a usb powered instead of serial port.<br><br>Thanks !
Indeed nice work , but what Shani_17pak says, it was nice if you placed the used components on the pcb's so the people don't have to search where to place the components. <br> <br>But keep up the good work.
where is the composant list ?! thanks ;) !!
nice work! but 1 think i need that you do not provide us that the component pcb layout that which component is solder on which hole. plese send that simple layout so i done my work thanks dear. i need it becuse i am new in this fieald and a hobbiest kindly help me out. bye (shani_17pak@yahoo.com)
Does anyone know how the voltage boost configuration works in the schematic, I'm familiar with that configuration working with AC coming in where Vcc is connected and RAx's being ground. <br>I assume there must be some kind of ripple or pattern generated on the RA0-3 pins.<br>Any ideas?
hello every body,<br>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 &quot;tantalum&quot; cap in the schematic so i hop if you can help at this and make a text list ??
Hi Keolerea, I just finished assembling the GTP USB and programmed the 18F2550 via a JDM2 Programmer. I tested it but WINPIC800 did not detect the hardware with a message "Failed to open Ind. #0". I implemented the hardware settings but WINPIC800 cannot saved the settings. Was copying the WINPIC 800 Folder to Program Files and launching it was all I had to do or did I miss a procedure. I also revised the PCB layout such that the final PCB was just a single sided type although a little bigger than the original design.. Hope to hear from you soon. Have a nice day.
Hi Butch_pastor,<br> I have the same problem youve got , did you manage to sort it out yet?? Please let me know.
I decided to stop further testing of the GTP programmer and has been successfully been using the USBPICProg of Frans Schreuder. You can check out this programmer at www.usbpicprog.org.<br>
Thanks for the reply will check it out
Hi Butch,<br> 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.<br>
Once I was finished with the assembly and all drivers, bootloaders and software installers downloaded, I start with the loading PIC18F2550 with the bootloader boot.hex and the firmware using another programmer (a JDM will do). Then I insert back the PIC to the newly assembled programmer that's it.<br><br>Then I install all the USB Lib files to PC (http://sourceforge.net/projects/libusb-win32/files/) and then install the Programming Software.<br><br>In selecting the files needed to be installed, choose the most recently released version.<br><br>That's all then you can start programming target PICs.<br><br><br>
Thanks will start building, will let you know how it goes. There is somebody on Facebook, MICROCHIP group, also looking for a USB programmer, but he waits for me to finish something succesful.
work on windows 7?<br>someone know if work on windows 7?<br>thank's all
think you
Sir,<br> 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............<br><br>Thanks in advance sir...............and gr8 work<br>
how program 18F2550 , in scheme ? or to another and then solder to the main ? thanks
ok, thanks...I resolved the problem...now it works very fine.<br>I need to buy a zif 40pin socket.<br>do you know if there is a web-site that offers the zif as FREE SAMPLE ? :)<br><br>bye<br><br>ninz0
