Hi
I have a bigger project with two different Arduinos. One is doing the math and collecting data (the due) and the other one is taking care of the User Interfacing (Knobs, buttons and Display).
So since I only have one board (custom designed) and only want to use one USB as output, my question is: Is it possible to program the Arduino AVR (I think I'll use a mega) with the DUE? Right now they're connected via I2c but serial connection could also be connected.
Its not a problem to erase the Due during Flashing or Flash a "Upgrading Firmware" Sketch on it since all the Settings are saved in an external Eeprom. After flashing the AVR, the Due Firmware hast to be installed again.
Since this is only done a few times (well, when I found a bug and want to upgrade the Firmware) this is no time critical process.
