Detailed Description

AudioAMP 11 Click example.

Description

This library contains API for the AudioAMP 11 click driver. This demo application shows use of a AudioAMP 11 click board™.

The demo application is composed of two sections :

Application Init

Initialization of I2C module and log UART. After driver initialization the app set default settings, performs power-up sequence, sets the volume level to 0.

Application Task

This example demonstrates the use of the AudioAMP 11 click board™. If GAIN SEL switches are set to 12dB, the app performs circles switching the volume from -20.5 dB to 12 dB. If the GAIN SEL switches are different, the app sets the volume level to 31 (maximum). Results are being sent to the UART Terminal, where you can track their changes.

Note

If USB_UART_RX and USB_UART_TX are defined as HAL_PIN_NC, you will need to define them manually for log to work. See LOG_MAP_USB_UART macro definition for detailed explanation.
