このライブラリでは、単音とメロディの出力が可能です。 In this library, you can output a single tone and melody. mbedのpwmOutとDigitalOutを使ってスピーカや圧電ブザーを直接駆動します。 directly drive speaker or buzzer and DigitalOut pwmOut using the mbed. メロディデータは、mbedのローカルにtxtファイルとして保存するか、プログラム中に配列データとして保存してください。 Melody data is either stored in a txt file on the local mbed, save it as a data array in the program.
