I have a basic knowledge of electronics so please bear with me. Do the capacitors have to be a particular voltage? I have some ceramic 200N and 100N which are rated to 50v. Could I use these?
TIA.

Any voltage rating over 5V will do. |

d4m4n,
the file that you have posted, is it for the nandpro 3 and if yes then when i flash it with picflash, then it is not recognized after the flash. please help.
Mine still works fine if i reflash it back to the old .hex file with nandpro 2 but for gligli hack i need the newer version.
thanks in advance.

You flash that file using the USB bootloader, a direct flash won't work. And it's not for nandpro3. There's no pic port for nandpro 3.

[quote author Arakon]You flash that file using the USB bootloader, a direct flash won't work. And it's not for nandpro3. There's no pic port for nandpro 3.[/quote] The hex file is for NandPro 2. And it can be flashed directly with Pickit 2&3 and other compatible flasher that also flash the configuration bits correctly. No need to use a bootloader if you have a proper flasher. I read the hex from a working unit and flashed it directly to 5 other units and all work just fine. hummer5: do you have the pin 17 disconnected? |

Hi guys I tested some bootloaders in here but they are all for 12mhz. Does anyone have bootloader to 20mhz?Otherwise I'll have to change the circuitry again
Thanks a million

Flash the bootloader with winpic800, it lets you change the settings for the speed.

Ok thanks for the reply. So u mean that bootloader is for any crystal. I need to set it when flashing, right? Thanks |

Pretty much yeah, you just need to set the fuse for the right divider depending on the crystal speed you used, and that is only programmed when you program the bootloader. Basically, whatever crystal you use, the PIC needs 48MHz to work... so if you used a 12MHz xtal the fuse is set to divide the clk by 4 to get 48MHz. |

posted this some weeks ago at X-S: Xbox360_USB_SPI_4-20MHz_incl.BootLoader_PicXFlash_V3b_plus2.zipPICFLASH.hex and PicXBoot.hex bootloader are both integrated in one .hex ready to burn (with PIC Programmer) for osc. 4 to 20 MHz jumper always opened, for direct use afterwards, without the need of PDFSUSB.exe, (bootloader may be used later as usual, if needed) at this point I wanna say a BIG THX to DarkStarTM & cory1492, who made this possible |

Will the hex work for pic18f4550? |

Great collection and very helpful. Thank you!! You don't know whether there are any Gerber file uploads for making PCBs do you? Thanks again for that great list of links. Huge time saver. EDIT: Even better, if someone could simply confirm that the design below would work, I'd really appreciate it. Schematic = http://www.ladyada.net/images/usbtinyisp/usbtinyisp2sch.png |

I Received PIC18f4550 dev. board ,it has 20Mhz crystal with bootloader preprogrammed,
When i tried to program USB_SPI_20MHz_(incl.BootLoader)_PicXFlash_V3b.hex every time i greeted with the configuration settings mismatch,I was given three options YES|NO|CANCEL, Whatever i select i get "failed to program flash"
I tried picflash.hex from first page ,flashes fine and i could get the memoryaccess in device manager ,But the problem is mines 20Mhz crystal instead of 12Mhz,
so,
Can somebody please help me with the changes needed in source for 20Mhz crystal,and compiling or provide me picflash.hex compiled for 20Mhz with out
bootloader part (which was failing)

USB_SPI_20MHz_(incl.BootLoader)_PicXFlash_V3b.hex is not for PDFSUSB.exe / it's for flashing with PIC Programmer when there isn't already a bootloader on the PIC. You don't need any changes for picflash.hex (only when burning the bootloader PicXBoot.hex the crystal frequ. has to be adapted in fuseset as mentioned above^^) - in your case this is already done. ... so your flashed picflash.hex should do the job as expected btw. use PICFLASH.hex from PICFLASH_v3b_plus2 by Cory1492 ^^ for NandPro2.0e |
