Thank you for help. Could you tell me how did you burn the bootloader? I downloaded the mega-isp and loaded it in the arduino IDE. Then I hooked 6 pins of the rainbowduino ISP up to an arduino according to the figure.
I selected “Arduino NG or older w/ ATmega168” in the board option and clicked Burn Bootloader with w/ AVR ISP. And then the java program had no response at all after a few minutes. Did I do something wrong? Thank you very much!
