Library Description

Library contains all the necessary functions for control to the AudioAmp 6 click.

Key functions:

• void audioamp6_setMode(uint8_t mode) - Sets MODE BD or 1SPW.
• void audioamp6_setOutput(uint8_t out) - Enable or Disable output.
• void audioamp6_setGain(uint8_t gain) - Sets Gain 20dB or 26dB.

Examples description

The application is composed of the three sections :

• System Initialization - Sets the necessary gpio pins to control the click.
• Application Initialization - Initializes the driver init and sets initial settings for the chip.
• Application Task - Waits for valid user input and executes functions based on set of valid commands.

Commands : 'e' - Enable/disable output 'g' - Changes the gain settings (20dB - 26dB)

Additional notes and informations

Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
