PIC USB Programmer

[EE42]

does anyone have experience with THIS USB Programmer ?

I bought one of these programmers, the Olimex pic-mcp-usb, but wish I hadn't.

It doesn't support all the chips they advertise.

If you upgrade the firmware to support new chips, you loose the ability to program some of the old ones. Apparently they ran out of programming space.

The firmware upgrader is designed so that you can never go back to a prevous version. The onboard chip is code protected so you can't copy it before doing an upgrade.

They don't tell you any of this, and you won't find out until you try to program a non-supported chip and you get the error message: "Structure transfer unsuccessful. Please reset PICSTART Plus."

It may take you hours to figure out what is going on because this is not documented anywhere.

If you own this programmer and it is working for you, then NEVER UPGRADE THE FIRMWARE.

If you do, you may loose the ability to program the chips you need. The company (Olimex) will not remedy this. You will have to buy a new programmer.

Original version is here , http://perso.wanadoo.es/siscobf/winpic800.htm .
This version support ZIF adapter for F series and ICSP.
The zip files included : schematic, soft programmer (the best), firmware (18F2550) and USB drivers.


Enjoy it.

Hello

I am using that software, its really nice.

I was sick of extracting the zipped file and put winpic800 in the program files directory, so I made it as a setup file, if ny intrested, I can upload it here

Sanpic,

Can you upload/share the WORKING GTP-USB Lite programmer .... schematic,firmware(hex code),PCB & guide(if any) ... if possible in zip format.

I tried many sch & firmware on the net but fail ....

If you can share it, I thks you very very very much ... Now I'm using laptop with no serial port & i need to go to my friend house (40km ++) just to program PIC .... real badddddd ....
