環境構築

Python 2.7.xをインストール Python 2.7.18 - Python.org

Arduino IDE 1.8.xをCドライブ直下にインストール Arduino software

C:\arduino\hardware\tools\avr\bin\ このパスが辿れることを確認

IDE 2.x以降はディレクトリ構成が変わったため使用不可

Arduinoへ書き込み

python flash.py COMxもしくはpy -2 flash.py COMxで書き込み (COMは各自確認)

以下、実行結果 (参考)

code:cmd

C:\firmware>py -2 flash.py COM5

Using serial device 'COM5' from command line.
