Click library

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

Software Support

We provide a library for the DualLin Click as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.

Package can be downloaded/installed directly form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.

Library Description

This library contains API for DualLin Click driver.

Standard key functions :

• Config Object Initialization function.

void duallin_cfg_setup ( duallin_cfg_t *cfg );

• Initialization function.

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

Example key functions :

• Sets state of RST pin

void duallin_bus1_status ( duallin_t *ctx, uint8_t state );

• Sets state of CS pin

void duallin_bus2_status ( duallin_t *ctx, uint8_t state );

• Send command.

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

Examples Description

This example reads and processes data from Dual LIN clicks.

The demo application is composed of two sections :

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
}

The full application code, and ready to use projects can be installed directly form compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

Other mikroE Libraries used in the example:

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

Additional notes and informations

Depending on the development board you are using, you may need USB UART Click, USB UART 2 Click or RS232 Click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all Mikroelektronika compilers, or any other terminal application of your choice, can be used to read the message.
