Operation

operationeffect
Right clickSounds
Left clickReset to base tone (C)
Moves the mouse to the rightLower the sound
Moves the mouse to the leftHigher the sound
Center cursorAdjust the sensitivity.
Reset the reference value in the click.

Others

The default setting of serial communication (baud rate etc.) in mbed is shown the following link.
Please refer to the link and change the settings of your PC terminal software.
The default value of baud rate in mbed is 9600, and this application uses baud rate 9600.

操作方法

操作内容
右クリック音出力開始
左クリック基準音(ド)にリセット
マウス右移動高音になります
マウス左移動低音になります
センターカーソル音高低の変化量調整(クリックで基準値にリセット)

Others

mbedのシリアル通信(ボーレート等)のデフォルト設定は以下のリンクに示しています。
リンクを参考に、お使いのPCターミナルソフトの設定を変更して下さい。
mbedでのボーレートのデフォルト値は9600で、このサンプルではボーレート9600を使います。
