This code is used in the Adafruit tutorial "Arduino Tips, Tricks, and Techniques" to reprogram AVR chips. https://learn.adafruit.com/arduino-tips-tricks-and-techniques/arduinoisp
March 2012 William Phelps - wm (at) usa.net
This is a fork of Adafruit's ArduinoISP which is a fork of Arduino's ArduinoISP which adds an 8 MHZ 'crystal' output on pin #9 so you don't need an extra oscillator/crystal. Can also rescue some bricked chips with bad oscillator fuses
Modified for Arduino IDE 1.0
- shorter serial port receive buffer requires changes
- getEOP() now gets entire request before avrisp() is called to process it
- Serial.print((char) xxx) changed to Serial.write(xxx)
- uint8_t changed to byte
- added support for Piezo speaker
- moved Pmode LED to A0
- removed "heartbeat" on pin 6, added short blip of ERROR LED instead
- Why is it that PROG_FLASH and PROG_DATA don't actually do anything???
Tested with Arduino IDE 22 and 1.0
- IDE 22 - 5148 bytes
- IDE 1.0 - 5524 bytes!
