Objective Development Forums

hello everybody
I have made the igor's usb interface without the IR part and it works very good. I success to control led. I would like to know if I can program my interface with your firmware and with which software ?
thanks
Lio

Perhaps I can compile the firmware with the WinAvr software but with which programer because I have programed igor's firmware with his schematic programer but i don't think than your programer is compatible with igor's schematic? Otherwise have you another schematic ?
thanks
Lio

I need help

a) There is no reason You couldn't use Obdev's firmware with Igor's schematics.

b) WinAvr should be ok, as for the programmer I would recommend avrdude (but this much depends on what OS You are using, it's easiest to do so with linux ;P )

c) Crying "I need help" just couple of minutes after You posted Your question is not very polite. Try looking for "nettiquete" in google

oki thanks for your response. I can use the obdev's firmware with winavr i have understand. But on my interface I have integrated a HE10 connector who use 2 jumper with which I have programmed the AVR from paralell port, my problem is that it's igor who has designed this programmer and I don't know if it works with WinAvr ? I don' know if I must have an another programmer schematic who will works with WinAvr?

If this is an ISP programmer (it must connect to GND/RESET/MISO/MOSI/SCK on the MCU), than You can define Your own parallel port programmer in the config of avrdude. Just edit the config file...

Yes it's an ISP it works very good, but how do we edit the config file ?

You can probably even use Igor's programmer. If the programmer accepts a Intel-Hex file, just send your own project's hex file instead of Igor's.

If you use avrdude: You probably don't need to edit anything. It comes with a configuration for all known parallel port programmers, you just need to know the name.

Please also note that you can't simply flash the firmware for an AVR-USB project and expect that it works on Igor's hardware. You must AT LEAST edit usbconfig.h to configure pins and interrupt.

oki I have understand but I must edit my hex file that would works with the igor's exe not the usb demo application but its programmer exe, and in this case I must modify some parameters in this exe and i don't know how does it works. and also edit usbconfig file is just indicate name pins with the usb pins ???

I see, igor's programmer includes the firmware file in the executable.

There are many parallel port programmers available for zero-cost AVR programming. See for example http://www.serasidis.gr/circuits/avrprog/avrprog.htm or search the web for low cost AVR programmers. You may even find programming software which is compatible with Igor's pin assignment.
