C++ API support for the ISD1820 based Grove Recorder. More...

Detailed Description

• ID: isd1820
• Name: Grove Recorder v1.0
• Category: sound
• Manufacturer: seeed
• Connection: gpio

This class implements support for the Grove 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 = new upm::ISD1820(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 sleep for 15 seconds

  if (doRecord)
    recorder->record(true);
  else
    recorder->play(true);
    
  // There are about 10 seconds of recording/playback time, so we will
  // sleep for a little extra time.
  cout << "Sleeping for 15 seconds..." << endl;
  sleep(15);

  // now, turn off whatever we were doing.

  if (doRecord)
    recorder->record(false);
  else
    recorder->play(false);
