Audio Amp 5 Click

AudioAmp 5 Click demo application is developed using the NECTO Studio, ensuring compatibility with mikroSDK's open-source libraries and tools. Designed for plug-and-play implementation and testing, the demo is fully compatible with all development, starter, and mikromedia boards featuring a mikroBUS™ socket.

• Type : GPIO type

Software Support

Example Description

This example consist of sending special commands for audio output control, selecting different output modes and turning on/off the audio output.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.AudioAmp5

Example Key Functions

• audioamp5_cfg_setup Config Object Initialization function.

void audioamp5_cfg_setup ( audioamp5_cfg_t *cfg );

• audioamp5_init Initialization function.

err_t audioamp5_init ( audioamp5_t *ctx, audioamp5_cfg_t *cfg );

• audioamp5_default_cfg Click Default Configuration function.

void audioamp5_default_cfg ( audioamp5_t *ctx );

• audioamp5_mode_select Function puts a device to the desired mode.

void audioamp5_mode_select ( audioamp5_t *ctx, uint8_t state );

• audioamp5_gain_select Function performs a desired gain selection.

void audioamp5_gain_select ( audioamp5_t *ctx, uint8_t state );

• audioamp5_config_update Function to update the configuration of the module.

void audioamp5_config_update ( audioamp5_t *ctx );

Application Init

Initializes GPIO interface on the desired mikrobus selection, and performs a device init configuration.

void application_init ( void )
{
    log_cfg_t log_cfg;
    audioamp5_cfg_t cfg;

    /** 
     * Logger initialization.
     * Default baud rate: 115200
     * Default log level: LOG_LEVEL_DEBUG
     * @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 @b LOG_MAP_USB_UART macro definition for detailed explanation.
     */
    LOG_MAP_USB_UART( log_cfg );
    log_init( &logger, &log_cfg );
    log_info( &logger, "---- Application Init ----" );

    //  Click initialization.

    audioamp5_cfg_setup( &cfg );
    AUDIOAMP5_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    audioamp5_init( &audioamp5, &cfg );

    audioamp5_default_cfg( &audioamp5 );
    log_printf( &logger, "** Audio Amp 5 is initialized **\r\n" );
    Delay_ms ( 500 );
}

Application Task

Checks the entered command and, if the command is valid, performs a device configuration which the entered command determines.

void application_task ( void )
{
    //  Task implementation.
    
    audioamp5_gain_select( &audioamp5, AUDIOAMP5_GAIN_26DB );
    audioamp5_config_update( &audioamp5 );
    log_printf( &logger, "** Gain value is 26dB **\r\n" );    

    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    audioamp5_gain_select( &audioamp5, AUDIOAMP5_GAIN_20DB );
    audioamp5_config_update( &audioamp5 );
    log_printf( &logger, "** Gain value is 20dB **\r\n" );  
    
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
}

Note

After each command for device configuration, the command for configuration updating will be executed. When BD Mode (0) is selected, the VIN supply voltage threshold is 7.5V. When Low-Idle-Current 1SPW Mode is selected, the VIN supply voltage threshold > is 3.4V.

Application Output

This Click board can be interfaced and monitored in two ways:

• Application Output - Use the "Application Output" window in Debug mode for real-time data monitoring. Set it up properly by following this tutorial.
• UART Terminal - Monitor data via the UART Terminal using a USB to UART converter. For detailed instructions, check out this tutorial.

Additional Notes and Information

The complete application code and a ready-to-use project are available through the NECTO Studio Package Manager for direct installation in the NECTO Studio. The application code can also be found on the MIKROE GitHub account.
