Dual LIN Click

Dual LIN 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 : MikroE Team
• Date : Apr 2020.
• Type : UART GPS/GNSS type

Software Support

Example Description

This example reads and processes data from Dual LIN Clicks.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.DualLin

Example Key Functions

• duallin_cfg_setup Config Object Initialization function.

void duallin_cfg_setup ( duallin_cfg_t *cfg );

• duallin_init Initialization function.

err_t duallin_init ( duallin_t *ctx, duallin_cfg_t *cfg );

• duallin_bus1_status Sets state of RST pin.

void duallin_bus1_status( duallin_t *ctx, uint8_t state );

• duallin_bus2_status Sets state of CS pin.

void duallin_bus2_status( duallin_t *ctx, uint8_t state );

• duallin_send_command Send command.

void duallin_send_command ( duallin_t *ctx, char *command );

Application Init

Initializes driver, and sets bus.

void application_init ( void )
{
    log_cfg_t log_cfg;
    duallin_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.

    duallin_cfg_setup( &cfg );
    DUALLIN_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    duallin_init( &duallin, &cfg );

    duallin_bus1_status( &duallin, DUALLIN_PIN_STATE_HIGH );
    duallin_bus2_status( &duallin, DUALLIN_PIN_STATE_LOW );
    Delay_ms ( 100 );
}

Application Task

Reads the received data.

void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
    duallin_process( );
#endif    

#ifdef DEMO_APP_TRANSMITER
    duallin_process( );

    if ( send_data_cnt = 2 )
    {
        duallin_send_command( &duallin, TEXT_TO_SEND );
        duallin_process( );
        send_data_cnt = 0;
    }
    else
    {
        send_data_cnt++;
    }    
#endif
}

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.
