This class implements support for the Grove Voice Recorder. There are two digital pins: one that enables recording, and the other that plays back what was previously recorded.

    // Instantiate a ISD1820 on digital pins 2 (play) and 3 (record)
    // This example was tested on the Grove Recorder.

    upm::ISD1820 recorder(2, 3);

    // if an argument was specified (any argument), go into record mode,
    // else playback a previously recorded sample

    cout << "Supply any argument to the command line to record." << endl;
    cout << "Running this example without arguments will play back any " << endl;
    cout << "previously recorded sound." << endl;
    cout << "There is approximately 10 seconds of recording time." << endl;

    cout << endl;

    bool doRecord = false;

    if (argc > 1)
        doRecord = true;

    // depending on what was selected, do it, and upm_delay for 15 seconds

    if (doRecord)
        recorder.record(true);
    else
        recorder.play(true);

    // There are about 10 seconds of recording/playback time, so we will
    // upm_delay for a little extra time.
    cout << "Sleeping for 15 seconds..." << endl;
    upm_delay(15);

    // now, turn off whatever we were doing.

    if (doRecord)
        recorder.record(false);
    else
        recorder.play(false);
