Is it possible to install the standard AVR firmware on a 3Pi 328P after the Arduino firmware has been installed? If so, how would this be done?
Gaah, I guess I didn’t read it all the way through. I don’t have to install the Arduino bootloader. Nevermind.
I am glad you figured it out. Typically, people do not put the Arduino bootloader on their 3pi, because you can use the Arduino environment and an AVR programmer to simply write your program directly to the AVR. For others who might be wondering the answer to the original question, yes, if you do write the Arduino bootloader to your 3pi, you can reprogram it later with the original 3pi demo program, or other programs.
