Wiring bootloader V1. (STK500 compatible)
    for Wiring board
    supported all Wiring software

    Base on Jason P. Kyle 's stk500boot.c bootloader,
    I put some code for "wait timer (8 sec.)" like Wiring board V1 Bootloader
    and another build for "Push button switch" enter mode "Bootloader" or "Run"
    on powering (need only pin for switch but zero waiting waste time..)

    Note: this bootloader purpose to work uisp and avrdude which using on Wiring only, not for AVRStudio STK500 plugins..

    Update 2 (20080412): change LED to PG0 (Wiring Board original used)
    Update 1 (20080321): Enable Universal SPI for AVRDUDE signature read
      when using AVRDUDE, may be called like this:
      > avrdude -c stk500 -p m128 -P com5 -b 115200 -D -V -U flash:w:test.hex -u -q

    Compiled code
      LED PG0
    • Use Wait timer method (about 8 sec.) to enter bootloader with active high LED indicate on PG0
    • Use active low Push button switch on PE2 to enter bootloader with active high LED indicate on PG0

      • LED PG2
    • Use Wait timer method (about 8 sec.) to enter bootloader with active high LED indicate on PG2
    • Use active low Push button switch on PE2 to enter bootloader with active high LED indicate on PG2

    Wiring bootloader V2. (STK500V2 compatible)
    for Wiring board
    supported Wiring 0014 or later software

    Original from Peter Fleury's STK500V2 compatible bootloader,
    I put some code for "wait timer (8 sec.)" like Wiring board V1 Bootloader
    and another build for "Push button switch" enter mode "Bootloader" or "Run"
    on powering (need only pin for switch but zero waiting waste time..)

    Update 2 (20080412): change LED pin to PG0
    Update 1 (20071229): using CMD_SPI_MULTI and return 0x00 for all un-implemented command, for AVRDUDE happy and get work
      when using AVRDUDE, may be called like this:
      > avrdude -c stk500V2 -p m128 -P com5 -b 115200 -D -V -U flash:w:test.hex -u -q

    Compiled code
      LED PG0
    • Use Wait timer method (about 8 sec.) to enter bootloader with active high LED indicate on PG0
    • Use active low Push button switch on PE2 to enter bootloader with active high LED indicate on PG0

      • LED PG2
    • Use Wait timer method (about 8 sec.) to enter bootloader with active high LED indicate on PG2
