Detailed Description

Audio Amp 2 Click example.

Description

This application amplifies the sound on the speakers.

The demo application is composed of two sections :

Application Init

Initializes GPIO driver and puts device in Standby Mode as default operation mode and selects 20dB as default gain selection.

Application Task

Activates Mute operation mode for 4 seconds and after that activates Play mode. When the device is in Play mode then changes the gain selection, first sets the minimum gain (20dB) for 8 seconds and then sets the maximum gain (32dB) for 8 seconds too.

note: Internally, the gain is set by changing the feedback resistors of the amplifier.
