2x30W Amp Click

2x30W 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 Key Functions

• c2x30wamp_cfg_setup Config Object Initialization function.

void c2x30wamp_cfg_setup ( c2x30wamp_cfg_t *cfg );

• c2x30wamp_init Initialization function.

err_t c2x30wamp_init ( c2x30wamp_t *ctx, c2x30wamp_cfg_t *cfg );

• c2x30wamp_enable Device Enable function.

void c2x30wamp_enable( c2x30wamp_t *ctx, uint8_t state );

• c2x30wamp_mute Device Mute function.

void c2x30wamp_mute( c2x30wamp_t *ctx, uint8_t state );

• c2x30wamp_check_diagnostic Diagnostic Check function.

uint8_t c2x30wamp_check_diagnostic( c2x30wamp_t *ctx );

Application Init

Initializes GPIO driver and enables the device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    c2x30wamp_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.

    c2x30wamp_cfg_setup( &cfg );
    C2X30WAMP_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    c2x30wamp_init( &c2x30wamp, &cfg );

    c2x30wamp_enable( &c2x30wamp, C2X30WAMP_ENABLE );
    log_printf( &logger, "2x30W AMP is initialized \r\n" );
    Delay_ms ( 200 );
}

Application Task

Mute output for a period of 3 seconds, then keep it unmuted for a period of 10 seconds. After that, checks if over current fault, over temperature fault or too high DC offset fault occurred.

void application_task ( void )
{
    c2x30wamp_mute( &c2x30wamp, C2X30WAMP_MUTE );
    log_printf( &logger, "---------------------- \r\n" );
    log_printf( &logger, "MUTE \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    c2x30wamp_mute( &c2x30wamp, C2X30WAMP_UNMUTE );
    log_printf( &logger, "---------------------- \r\n" );
    log_printf( &logger, "UNMUTE \r\n" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );

    uint8_t fault_check = c2x30wamp_check_diagnostic( &c2x30wamp );

    if ( fault_check == 0 )
    {
        log_printf( &logger, "Fault condition! \r\n" );
    }
}

Note

When under or over voltage condition occurres the output goes to high impedance state, but the FAULT pin will not be asserted.

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.
