API support for the ISD1820-based Grove Voice Recorder. More...

Detailed Description

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)
// 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;
// now, turn off whatever we were doing.
