MUX 9 Click

MUX 9 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 example demonstrates the use of MUX 9 Click board™.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.MUX9

Example Key Functions

• mux9_cfg_setup Config Object Initialization function.

void mux9_cfg_setup ( mux9_cfg_t *cfg );

• mux9_init Initialization function.

err_t mux9_init ( mux9_t *ctx, mux9_cfg_t *cfg );

• mux9_active_channel MUX 9 active channel function.

err_t mux9_active_channel ( mux9_t *ctx, uint8_t sel_ch );

• mux9_reset MUX 9 reset function.

void mux9_reset ( mux9_t *ctx );

• mux9_disable MUX 9 disable function.

void mux9_disable ( mux9_t *ctx );

Application Init

Initializes the driver and performs the reset.

void application_init ( void )
{
    log_cfg_t log_cfg;    /**< Logger config object. */
    mux9_cfg_t mux9_cfg;  /**< Click config object. */

    /** 
     * 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.
    mux9_cfg_setup( &mux9_cfg );
    MUX9_MAP_MIKROBUS( mux9_cfg, MIKROBUS_1 );
    if ( SPI_MASTER_ERROR == mux9_init( &mux9, &mux9_cfg ) )
    {
        log_error( &logger, " Communication init." );
        for ( ; ; );
    }

    mux9_reset( &mux9 );
    log_info( &logger, " Application Task " );
    log_printf( &logger, " -----------\r\n" );
}

Application Task

This is an example that shows the use of a MUX 9 Click board™. This example shows switching channels (from CH 1 to CH 8) on and off. Results are being sent to the Usart Terminal where you can track their changes.

void application_task ( void )
{
    for ( uint8_t ch_pos = MUX9_SELECT_CH_1; ch_pos <= MUX9_SELECT_CH_8; ch_pos++ )
    {
        if ( MUX9_OK == mux9_active_channel( &mux9, ch_pos ) )
        {
            log_printf( &logger, " The Channel %d is activated. \r\n", ( uint16_t ) ch_pos );
            Delay_ms ( 1000 );
        }
    }
    log_printf( &logger, " -----------\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.
