PIC PSGrooPIC flashing/DIY guide, FAQ and hex files collections

[skygunner]

revised a lot, cleared out about MCLR, bootloader pin related stuff.
Also found this very useful article about how bootloader works,compile bootloader, change bootloader pin, how to compile user application to be compatible with bootloader etc and an alternative to the buggy PDFSUSB, everyone should have a read

made the revised diagram on psgroopic blogspot, flashed UID bootloader to device, then used the 2.6b program to write the 1.4 'patched' hex code to the chip.

It works

The problem I had was pin 15 was ready to bust off, so it was making contact to everything but the chip. God I hate microchip's! bad memories from the 12C509's we used 2 playstations ago!

So yes! LVP programming requires tie to GND of pin 26 to use bootloader/program!!

Which pin did you short to get into bootloader mode & flash it with 2.6b?

Asuming that you used their bootloader "Bootloader USB HID C18 18F2550Trainer: HEX + SRC"

The Xbox360 PSI/USB Flasher by Darkstar, only for if you have one or want to buy one
boot jump pin on 17, just use the original bootloader comes with it (name it xbox360 MCHPSUSB bootloader)
iLLNESS's builds has LED on B5

Hi,
I have a question. I'm using darkstar's diagram and it works.
I just wanna know which is the pin 13 function?
Why it takes 5v?
Is it necessary to give pin13 5v?
In other schematics this pin isn't used.

Has someone the source code .c (not the hex) for this schematics or can someone read the source and show me the function?

Thanks

First don't quote the full image, just name it.
Second the 360 spi usb flasher is not for DIY, only for the people who has it, maybe I didn't make it clear enough.
So don't ask why it has more components than the others.
You can try to read the source code yourself, the source code is there.1

[*]Cheap PIC programmer to make/buy?

Build a simple and cheap JDM programmer (HVP) like this one
http://www.instructables.com/id/Simp...IC-Programmer/

Just to let everyone know that tutorial seems to only bee good for 16f chips I dont belive it will do us any good.

hi~ MetalPhreak
can you help me?
I build psgroopic 1.2 schema , but my led connect pin22(RB1) .. did you help me compile 8MHZ(and 16Mhz) with LED on RB1 ?? thanks!!

i build psgroopic v1.0 everytings work with bootloader and 1.4 hex.. only second led dont blink..
i had ground pin 26..

does somebody know??

Any good and simple HVP programmer support 18F*?
