LGT8Fx8P ISP download protocol implementation

introduction

This is an implementation of LGT8Fx8P ISP download protocol. You can make arduino board as ISP for programing LGT8Fx8P.

usage

1. Make a LGTISP:
   1. Burn LGTISP into arduino board.
   2. Short RESET pin and VCC pin of arduino board to avoid bootloader executing.
   3. The arduino board becomes a LGTISP now! Connect SWD and SWC. RST can be either connect or not.

      Arduino Nano		LGT
      D13	->	SWC
      D12	->	SWD
      D10	->	RST

2. Burn bootloader into LGT8Fx8P:
   1. install Larduino.
   2. change Board to LGT8Fx8P.
   3. change Programmer to AVR ISP.
   4. click Burn Bootloader!

advanced usage

• You can read GUID!
• You can read almost all flash after power-down! I crack it, haha
• more details : LGTISP programmer
• Explore yourself!
