Library Description

Library offers a choice to put the device in desired mode (Standby, Mute or Play Mode) and to select the gain to the desired value (20, 26, 30 or 32dB).
For more details check the documentation.

Key functions :

  • uint8_t audioamp2_setMode( uint8_t selMode ) - Function puts device in desired mode.
  • uint8_t audioamp2_setGain( uint8_t selGain ) - Function performs the gain selection.
  • uint8_t audioamp2_checkDiagnostic( void )- Function checks isundervoltage, overcurrent or thermal protection activated.

Example description

The application is composed of three sections :


System Initialization - Initializes peripherals and pins.
Application Initialization - Initializes GPIO driver and puts the device in Standby Mode as default
operation mode and selects 20dB as default gain selection.
Application Task - (code snippet) - 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.

void applicationTask()
{
audioamp2_setMode( _AUDIOAMP2_MUTE_MODE );
Delay_ms( 4000 );
audioamp2_setGain( _AUDIOAMP2_20DB_GAIN );
audioamp2_setMode( _AUDIOAMP2_PLAY_MODE );
Delay_ms( 8000 );
audioamp2_setGain( _AUDIOAMP2_32DB_GAIN );
Delay_ms( 8000 );
}

Additional notes and information

Depending on the development board you are using, you may need USB UART clickUSB 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.
