VSCodeとDAPLink/CMSIS-DAPボードの接続設定
こんにちはリゲル・インテリジェンスです。
DAPLink/CMSIS-DAPボードをOpenOCDに接続出来ましたので、いよいよVSCode（Visual Studio Code）を設定しRP2040をデバッグ出来るようにします。
動作確認用のサンプルコードを含めたフォルダ構成は下記のようにします。（buildフォルダは自動生成されます）

.vscodeフォルダ内の各々のファイルを設定します。

VSCodeを起動する前にターミナルにて「PICO_SDK_PATH」を設定しておきます。

export PICO_SDK_PATH="[pico-sdkのインストールフォルダ]/pico-sdk" |
次ページにてVSCodeを起動し、動作を確認していきます。
