ビルド・動作確認方法

プロジェクト設定では「\Application\_Exclude\USBD」フォルダはビルド対象外に設定しています。以下のどちらかの方法で動作確認を行うサンプルアプリケーションを選択します。

  1. 「\_Exclude\USBD」フォルダ下の対象テストサンプルファイルをビルド対象設定の「\Application」フォルダ下にコピーします。
  2. 「\_Exclude\USBD」フォルダ下の対象テストサンプルファイルのみ「ビルド対象外」の設定を解除します。

各テストアプリケーションの動作確認方法はテストサンプルアプリケーションのヘッダのコメント情報を参照ください。

プロジェクトを再ビルドし、EK-RX671評価ボードに接続してデバッグセッションを開始します。
テストアプリケーションの要件に合わせてJ29 USBポートをパソコンに接続してプログラムを実行します。デバッガのIOコンソールのログ画面から結果を確認します。

J29 USBポートのデバイスモード設定：

usbd setting

評価ボードのジャンパー設定でJ29 USBポートをDEVICEモードに変更します。

  • J30：Jumper on pins 1-2
  • J31：Jumper on pins 2-3
  • J32：Short
  • J33：Jumper on pins 1-2
