Hex through dfu, but it failed, apparently because dfu could not.
And first of all, you need to download the two firmware files arduino-usbserial-.
To burn the usb serial firmware back to atmega16u2 turn the hid keyboard device back to a normal arduino uno board.
In this video we will show you how to generate hex file from arduino ide software.
If you saved the firmware in your downloads folder on osx, then you might type cd downloads once there, type sudo dfu-programmer atmega16u2 erase. When this command is done and you get a command prompt again, type sudo dfu-programmer atmega16u2 flash arduino-usbserial-uno.
Locate the bootloader hexadecimal or hex file for the arduino uno which is included with the. Elcodis, view and download atmega16u2 pdf datasheet, atmel corporation specifications.
