Arduino ISP Programmer 2-in-1

Overview

Use the switch on the board to switch the ISP programming and serial port debugging functions.

The board provides ISP status indication, serial port Tx and Rx status indication LEDs.

ICSP and serial port connectors are provided on the board.

The ATmega328P on the board needs to be pre-programmed with the ArduinoISP program provided by the official IDE before soldering.

If you want to use the LGT8F328P chip programming provided by Nulllab, you need to pay attention to:
(1) The ATmega328P on the board can be replaced by LGT8F328P. No matter what chip is used, you need to pre-program the "LarduinoISP for LGT8FX8D series" program provided by Nulllab (on Nulllab Curry has).
(2) The ISP indicator light is difficult to use. Users can modify the "LarduinoISP for LGT8FX8D series" program provided by Nulllab to assign functions to the indicator light.
(3) The ICSP interface needs to be rewired according to the wiring sequence on the Nulllab board.

Attached is a shell I made for avrdude.exe using Python, which can be used with this hardware to program the Arduino microcontroller.
