Single Click or Alert Example

The following programming example shows how to initialize the device and send a simple Mode 3 (Waveform Synthesis Playback mode) transaction. If the number of cycles is short (< 10), the effect is a click, and if the number of cycles is long (> 10) the effect is a buzz alert.
