LGTISP

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.

Make a LGTISP:
1. Select SERIAL_RX_BUFFER_SIZE to 250 in Menu: Tools/Arduino as ISP/SERIAL_RX_BUFFER_SIZE to 250
2. Burn LGTISP into another LGT328p board.
3. Select Default in Menu: Tools/Arduino as ISP/Default
4. Short RESET pin and VCC pin of ISP board to avoid bootloader executing.
5. The 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 |
Burn bootloader into LGT8Fx8P:
1. change Programmer to AVR ISP.
2. click Burn Bootloader or upload sketches directly through the menu: Sketch/Upload using programmer
