It would be nice if the width between the left side and right side was slightly narrower so that it could sit flush without angling the atmega8u2 dfu. Okay, this is way harder than it needs to be or way easier than I can see it being.

Here are the instructions I am trying to follow: instructions I am stuck at -grab hex and -change fuses. I cannot figure out inside AVR Studion 4. I did not compile this in Atmega8u2 dfu Studio either.

I did it from the command line using WinAVR. I cannot load the firmware I compiled nor the firmware you atmega8u2 dfu. To check which version of the firmware is on your board, connect it to your computer and follow the directions for your operating system: Windows before 7 : locate the board in the Device Manager it should be under Portsright click on it and select "Properties"; in the resulting dialog, click on "driver details" in the "Driver" tab "Details" in Windows 7.

Obviously, you can stick atmega8u2 dfu on there thru the ISP, but I'm mainly atmega8u2 dfu curious how to know if you got an 8u2 with the DFU loaded or not from the factory. Seems like ATmel should have this stated clearly, one way or the other. Log in or register to post comments. Go To Last Post.

This one gave me a lots of headache. Product Document.Updating the Atmega8U2 and 16U2 on an Uno or Mega using DFU be updated through atmega8u2 dfu special USB protocol called DFU (Device Firmware Update). The ATmega8U2 chip on your Arduino board acts as a bridge between the computer's USB port and the main processor's serial port.
