AMFM Click

AM FM 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

• amfm_cfg_setup Config Object Initialization function.

void amfm_cfg_setup ( amfm_cfg_t *cfg );

Application Init

Initializes device.

void application_init ( void )
{
    log_cfg_t log_cfg;
    amfm_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.

    amfm_cfg_setup( &cfg );
    AMFM_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    amfm_init( &amfm, &cfg );

    Delay_ms ( 100 );
    status = amfm_init_device( &amfm );
    if ( 0 == status )
    {
        log_printf( &logger, "> > > app init done < < <\r\n" );
    }
    else if ( 1 == status )
    {
        log_printf( &logger, "> > >    timeout    < < <\r\n" );
    }
    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.
