Detailed Description

VUMeter Click example.

Description

This example demonstrates the use of VU Meter click board.

The demo application is composed of two sections :

Application Init

Initializes the driver and sets the gain level (the microphone sensitivity) to maximum.

Application Task

Calculates VU level from the analog voltage read from AN pin, and displays the results on the USB UART approximately every 100ms.
