Pi:Co Classic4用 Arduino サンプルスケッチ集です。
5+
6+
## 動作環境
7+
- Arduino IDE v2.3.4
8+
- Arduino-ESP32 v3.1.3
9+
- Async TCP 3.3.6
10+
- ESP Async WebServer 3.7.1
11+
12+
## サンプルプログラムについて
13+
### STEP1 〜 STEP8
14+
15+
- Pi:Co Classic4のハードウェアを動かすための、Arduinoスケッチの書き方をまとめています
16+
17+
## スケッチファイルの自動整形について
18+
- ソースコードのレイアウトを整えるため、各スケッチファイルにはArduino IDEの自動整形を適用しています。 自動整形のルールは[.clang-format](.clang-format) ファイルを参照してください。
