MUX Click

MUX 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.

Click Library

• Author : Luka Filipovic
• Date : Nov 2019.
• Type : GPIO type

Software Support

Example Description

Sets the current active channel. Changes the channel every 5 sec.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.Mux

Example Key Functions

• mux_cfg_setup Config Object Initialization function.

void mux_cfg_setup ( mux_cfg_t *cfg );

• mux_init Initialization function.

err_t mux_init ( mux_t *ctx, mux_cfg_t *cfg );

• mux_default_cfg Click Default Configuration function.

void mux_default_cfg ( mux_t *ctx );

• mux_active_mux_channel Seelect active MUX channel.

void mux_active_mux_channel ( mux_t *ctx, uint8_t sel_ch );

• mux_device_disable Disable MUX device function.

void mux_device_disable ( mux_t *ctx );

• mux_device_enable Enable MUX device function.

void mux_device_enable ( mux_t *ctx );

Application Init

Initializes GPIO module and sets RST, CS and PWM pins as OUTPUT.

void application_init ( void )
{
    log_cfg_t log_cfg;
    mux_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.

    mux_cfg_setup( &cfg );
    MUX_MAP_MIKROBUS( cfg, MIKROBUS_POSITION_MUX );
    mux_init( &mux, &cfg );
    Delay_ms ( 100 );
    
    log_printf( &logger, "        MUX Click\r\n" );
    log_printf( &logger, "------------------------\r\n" );
    
    mux_device_enable( &mux );
    log_printf( &logger, "    Enable MUX device\r\n" );
    log_printf( &logger, "------------------------\r\n" );
    Delay_ms ( 100 );
}

Application Task

Changes currently active channel every 5 sec.

void application_task ( void )
{
    uint16_t n_cnt;
    
    for ( n_cnt = MUX_CHANNEL_1A_AND_1B; n_cnt < MUX_CHANNEL_END; n_cnt++ )
    {
        log_printf( &logger, "      CHANNEL  S%u\r\n", n_cnt );
        log_printf( &logger, "------------------------\r\n" );
        
        mux_active_mux_channel( &mux, n_cnt );
        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.
