I've built a gtp-usb+ (summer edition) programmer. I use it with winpic800 (3.55f) but when I try to program a pic (18F4585, but have tried others) it says "Error - No is answer of hardware" or something like that. I've measured the voltage on the programmer and it seems right, VPP is about 10.5V, maybe it should be slightly more but I don't know

Hi there, currently i have a gtp usb Lite prog. I'm using Winpic800 v3.55 to prog my PIC in XP. Anyone has the usb driver and firmware(18f2550) for it to work in Vista? Thanks.
Hi, I started this topics to see if gtp-usb lite users or makers are having problems with their home-made hardware. who knows i might solve it
gtp usb+ is not free. The others are. Suggestion: forget about the gtp and build a PicKit2. Blueroomelectronics has an excellent kit (Junebug). It is, however, limited to 5v devices. funnynypd also has an excellent kit. It programs both 3v and 5v devices, but uses smt/smd components (not as easy to build). Last I heard, he was (...)
Hello, everyone, I built the programmer gtp-usb-# 0 and use WINPIC800 V3.55g. I have the following problem: I can not program the pic.

I recently built a gtp usb Lite programmer following the documentation on When i connect it to my pc , it does not detect the programmer giving a "usb device not recognized" error. I dont think that there are any hardware errors in my circuit. I cant understand why the circuit does not work. Also (...)
download it and find ur requerment
with the pickit2 you can program AND debug (trace) your programs. the gtp is only for programming. also the gtp usb lite works only with winpic v3.55 - so there are quite no updates for new pics since a long time. so for me pickit2 wins.
I need the hex file of gtp usb Plus...Please mail it to me Thanks
hi here is gtpusb plus firmware it is basically pickit2 firmware moded to work with gtp usb plus version hardware you have to program the chip with this firmware regards Fragrance
dear friend i made gtp-usb plus but i don't have firmware so if any body having firmware of gtp-usb plus so send me at and i tried old firmware of gtp-usb summer is not working. thanking
better build a pickit2 (clone) or icd2 (clone) today than trying to make a gtp usb clone which , in its free version, doesnt support recent pics... you must use a gtp usb LITE and the gtp software v3.55 if any of the two is not right, nothing can work.
hello guys i need 'gtp usb 2005 summer driver' for VISTA or WIN7 thanks for your helping Added after 12 minutes: oh.. notice: NOT for xp or gtp usb + (plus)

Hello. I am new to this forum. Does anyone know have a schematic for a usb Programmer? I have built the gtp usb-lite programmer, but windows didn't recognized it, it says "Unknown device", even thow I have installed the usb drivers. Thank you. What version of winpin800 are you using?

you can also make yourself a icd2 clone (the one with full usb support - pic18f4550 and 16f877) it is some more expensive, but it will program all the pics, and you can debug your program too... this usb jdm programmer will not program modern pics, and as it is still rs232 it will be very slow to program big pics with 16k or more flash in it...
Verify your cable usb (gtp usb needs cable usb 2.0 with maximum of length 1.8M). Do you have gtp-usb PLUS? If your gtp usb goes LITE then you need the usb host.
Hi, gtp usb for Pic. refer to:
I´ve problem when programming 16F627a in WinPic800 v3,55g and gtpusbLite. It say verify at 0x0000h. Other chips 18f2550 16f876A work fine. When I use JDM hw and WinPic800 verify OK but still can´t detect device ID I´m not sure if UTp usb LITE support this chip. /I must use usb vesion./ Any ideas...,? Please help (...)

Hhole project with original proteus pcb files....schematics, source code, assembly photos..... And..I get this code from some where.... basically its pickit2 code modified to use with gtp plus.... I'm working on others projects these days so didn't get time so uploading if anyone working on this project plz test this code and tell me so
As you say, If you have "bought" the usb programmer, ask the vendor about which is the programming software to be used with the same. If it is a Pickit2 clone, the Pickit2 programming software may be used. gtp usb, Brenner and other versions of usb based programmer and softwares are other possiblities.

Why not try the gtp-usb it supports pic programming and eeprom programming the plus version even supports atmel MCU.
I'm making this poll because I'm planning to buy a new laptop. I just want to make sure that the one I'll choose is recommended. I plan to use this in programming PIC microcontroller using gtp-usb-Lite. Please post your brand and OS used. Share your comments, experience and ideas. Thanks :D
Yes, winpic800 is a freeware. But if you want to use the full potential of the software, you need the programmer gtp usb+ from sisco. The (modified )JDM2 programmer does work with winpic800. I will check out if it will program a 16f684.... though i dont see any reason, why it should not.
