    GTP-USB will be sold as a kit and not software alone.
    it is mentioned on the site itself

    The Junebug is a much better program and device support if from Microchip so you do not have to depend on a 3rd party to update it for new devices. And as we said many time it is also a ICD (in circuit debugger), 3 channel logic analyizer, and a UART tool.

    But it will not program AVR's unless someone takes the time to write software for that. And the as we said earlier, why bother. There is no good reason for you to do AVR's and PIC at this point. Maybe never. If you want to go with AVR buy a AVR programmer/debugger like the Dragon.

    Silverblade,

    Just noticed your location as "the Motor City"... What's your name and where are you located? I'm in Westland... Finally, do you need any help or is there anything I can do to help you get started?

    Mike

    QUOTE from JUNEBUG Assembly Instructions April08:

    "Your kit includes a pre-programmed PIC18F2525 (PK2V021000.HEX) the firmware is automaticallyupdated by MPLAB when needed. If you have a problem with the firmware holding down SW5 (directly below the 18F2550 while you connect the USB cable should initiate the bootloader (busy LED flashing)Run either the PICkit 2 or MPLAB software to initiate a reinstall of the Junebug (PICkit 2) firmware."

    So If you assemble a kit supplied by Blueroomelectronics with a pre-programmed 18F2550, what you read is correct. Otherwise you may have to get the Firmware loaded thro' a known friend. Luckily for you, Mike k8lh has offered HELP in this very context.

    Nope--as far as I know, only Bill has the firmware code for the Junebug, seeing as it's a kit that he designed and sells on his site: http://www.blueroomelectronics.com

    I could not find Junebug firmware to download on Bill's site but the Inchworm programmer firmware is available on the Inchworm product page.

    Bill, by the way, is a long-time member of this site and is one of the top respected posters helping people out here. Perhaps if you ask him nicely he'll send you the firmware. However, I suspect that he charges money for it and since he makes money selling his Junebug kit I don't know how willing he'd be to just send the firmware to someone for free. I wouldn't. Maybe Bill is nicer than me though.

    Will the Inchworm firmware suffice? If not, I'd suggest just buying the Junebug kit. It's an amazing deal at $49. Or as was already suggested, a Dragon if you want to work with AVRs.

    I'm a professional programmer and even so, writing my own programmer code wouldn't be worth my time except as a weekend exercise. I'd just buy a real Junebug.

    Umm... Junebug is a PICkit 2 clone. That means it runs Microchip PICkit 2 firmware, right? Isn't the firmware you're looking for located in the Downloads section at the bottom of this page, listed as "PICkit 2 Firmware V2.32"?

    My apologies, you are absolutely right. I thought the Junebug was just compatible with custom firmware, not a clone.

    Futz is right, I was wrong: it looks like you can just download the code from MicroChip.

    yes, all the firmware and software you can download from MC site, but I recommend you download software and firmware version 2.50. because last time I have experience with Real PICKIT2 from MC, when I update to 2.52,sometime, there are error when I burn the chip. I just work fine with 2.50. I not sure the other members have same problem like me. May be it because of my laptop i used.
    Now I used 2.50 and it work fine.
    Best regard

    Hi Silverblade (Abbas Shah),

    Very nice to meet you.

    If you have the PIC and the hex file I would be happy to program them for you. Send me a PM when you're ready or have your parents PM me if you're a child.

    Mike

    :) Thank you Torben for the compliments. The Junebug (PICkit2) firmware can be found within MPLAB or the PICkit2 stand alone application both freely downloadable from Microchips web site.

    Look for BL01*.HEX or PK2V*.HEX

    MPLAB and PICkit2 software will autoupdate the firmware so you can pick either.

    The firmware will be extracted as part of the PICkit2 install, futz's link has the correct file.
