PlatformIOのシリアル通信をClaude Codeに解釈させる

PlatformIOのシリアル通信をClaude Codeに解釈させる

結論

非tty環境だとコケるらしく、何らかのコマンドでラップしてあげると動くので以下のように指示する

シリアル通信の受信はこのコマンドを run_in_background で実行してください
script -q /dev/null pio device monitor --port /dev/cu.usbmodem1101 --baud 115200

シリアル通信の送信はこのコマンドを実行してください
printf "送信したい内容" > /dev/cu.usbmodem1101

※ /dev/cu.usbmodem1101 と 115200 は各環境に依存する

エラー内容

ラップしていないときのエラー内容

     ============================================================

     An unexpected error occurred. Further steps:

     * Verify that you have the latest version of PlatformIO using
       `python -m pip install -U platformio` command

     * Try to find answer in FAQ Troubleshooting section
       https://docs.platformio.org/page/faq/index.html

     * Report this problem to the developers
       https://github.com/platformio/platformio-core/issues

     ============================================================

備考

logsを吐かせてClaude Codeに解釈させることでうまくいく
