c2x20W Amp Click

2x20W Amp 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.

Example Description

This application changes the volume level.

Example Libraries

• MikroSDK.Board

• Click.2x20WAmp

Example Key Functions

• c2x20wamp_cfg_setup Config Object Initialization function.

void c2x20wamp_cfg_setup ( c2x20wamp_cfg_t *cfg );

• c2x20wamp_init Initialization function.

err_t c2x20wamp_init ( c2x20wamp_t *ctx, c2x20wamp_cfg_t *cfg );

void c2x20wamp_set_volume ( c2x20wamp_t *ctx, uint8_t volume );

• c2x20wamp_mode_mute Set Mute mode of the amplifier function.

void c2x20wamp_mode_mute ( c2x20wamp_t *ctx );

Application Init

Initialization driver enable's - I2C, start write log and enable amplifire of 2x20W Amp Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c2x20wamp_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.

    c2x20wamp_cfg_setup( &cfg );
    C2X20WAMP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c2x20wamp_init( &c2x20wamp, &cfg );
    
    Delay_ms ( 100 );

    log_info( &logger, "-----------------------\r\n    2x20W Amp Click    \r\n-----------------------" );
    c2x20wamp_enable( &c2x20wamp );
    log_info( &logger,"   Enable  Amplifier   \r\n-----------------------");

    Delay_ms ( 200 );
}  

Application Task

This is a example which demonstrates the use of 2x20W Amp Click board. This examples first activates operation mode PLAY and set volume lvl 32 ( 50% ), after that, we increase the volume level one level ten times for 5 seconds and we decrease the volume level one level ten times for 5 seconds. And finally, we set MUTE mode for next 5 seconds. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
    int cnt;
    
    log_info( &logger, "       PLAY MODE       " );
    c2x20wamp_mode_play( &c2x20wamp );
    
    log_info( &logger, "-----------------------\r\n  Set Volume lvl : 32  " );
    c2x20wamp_set_volume( &c2x20wamp, 32 );

    log_info( &logger, "- - - - - - - - - - - -" );

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

    for ( cnt = 0; cnt < 10; cnt++ )
    {
        log_info( &logger, "       Volume Up       " );

        c2x20wamp_volume_up( &c2x20wamp );

        Delay_ms ( 100 );
    }

    log_info( &logger, "- - - - - - - - - - - -" );

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

    for ( cnt = 0; cnt < 10; cnt++ )
    {
        log_info( &logger, "       Volume Down       " );

        c2x20wamp_volume_down( &c2x20wamp );

        Delay_ms ( 100 );
    }

    log_info( &logger, "-----------------------" );

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

    log_info( &logger, "       MUTE MODE       " );

    c2x20wamp_mode_mute( &c2x20wamp );

    log_info( &logger, "-----------------------" );

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

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.
