MUX 2 Click

MUX 2 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.Mux2

Example Key Functions

  • mux2_cfg_setup Config Object Initialization function.
void mux2_cfg_setup ( mux2_cfg_t *cfg );
  • mux2_init Initialization function.
err_t mux2_init ( mux2_t *ctx, mux2_cfg_t *cfg );
  • mux2_default_cfg Click Default Configuration function.
void mux2_default_cfg ( mux2_t *ctx );
  • mux2_active_mux_channel Seelect active MUX channel.
void mux2_active_mux_channel (  mux2_t *ctx, uint8_t sel_ch );
  • mux2_device_disable Enable MUX device function.
void mux2_device_disable ( mux2_t *ctx );
  • mux2_device_enable Disable MUX device function.
void mux2_device_enable ( mux2_t *ctx );

Application Init

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

void application_init ( void )
{
    log_cfg_t log_cfg;
    mux2_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.

    mux2_cfg_setup( &cfg );
    MUX2_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    mux2_init( &mux2, &cfg );
    Delay_ms ( 100 );
    
    log_printf( &logger, "       MUX 2 Click\r\n" );
    log_printf( &logger, "------------------------\r\n" );
    
    mux2_device_enable( &mux2 );
    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 )
{
    uint8_t n_cnt;
    
    //  Task implementation.
    
    for ( n_cnt = MUX2_CHANNEL_S1; n_cnt < MUX2_CHANNEL_END; n_cnt++ )
    {
        log_printf( &logger, "      CHANNEL  S%d\r\n", n_cnt );
        log_printf( &logger, "------------------------\r\n" );
        
        mux2_active_mux_channel( &mux2, 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.
