// This sketch turns the Arduino into a AVRISP

// using the following arduino pins:

//

// pin name: not-mega: mega(1280 and 2560)

// slave reset: 10: 53

// MOSI: 11: 51

// MISO: 12: 50

// SCK: 13: 52

//

// Put an LED (with resistor) on the following pins:

// 9: Heartbeat - shows the programmer is running

// 8: Error - Lights up if something goes wrong (use red if that makes sense)

// 7: Programming - In communication with the slave

// -Address Arduino issue 509 :: Portability of ArduinoISP

// http://code.google.com/p/arduino/issues/detail?id=509

//

// October 2010 by Randall Bohn

// - Write to EEPROM > 256 bytes

// - Better use of LEDs:

// -- Flash LED_PMODE on each flash commit

// -- Flash LED_PMODE while writing EEPROM (both give visual feedback of writing progress)

// - Light LED_ERR whenever we hit a STK_NOSYNC. Turn it off when back in sync.

// - Use pins_arduino.h (should also work on Arduino Mega)

//

// October 2009 by David A. Mellis

// - Added support for the read signature command

//

// February 2009 by Randall Bohn

// - Added support for writing to EEPROM (what took so long?)

// Windows users should consider WinAVR's avrdude instead of the

// avrdude included with Arduino software.

// - Thanks to Amplificar for helping me with the STK500 protocol

// - The AVRISP/STK500 (mk I) protocol is used in the arduino bootloader

// - The SPI functions herein were developed for the AVR910_ARD programmer
