Single Wire CAN Click

Single Wire CAN 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 demonstrate the use of Single Wire CAN Click board.

Example Libraries

• MikroSDK.Board
• MikroSDK.Log
• Click.SingleWireCan

Example Key Functions

• singlewirecan_cfg_setup Config Object Initialization function.

void singlewirecan_cfg_setup ( singlewirecan_cfg_t *cfg );

• singlewirecan_init Initialization function.

err_t singlewirecan_init ( singlewirecan_t *ctx, singlewirecan_cfg_t *cfg );

• singlewirecan_set_operating_mode The function set desired operating mode of NCV7356 Single Wire CAN Transceiver.

void singlewirecan_set_operating_mode ( singlewirecan_t *ctx, uint8_t op_mode );

• singlewirecan_generic_write This function write specified number of bytes.

void singlewirecan_generic_write ( singlewirecan_t *ctx, char *data_buf, uint16_t len );

• singlewirecan_generic_read This function reads a desired number of data bytes.

int32_t singlewirecan_generic_read ( singlewirecan_t *ctx, char *data_buf, uint16_t max_len );

Application Init

Initializes the driver and configures the Click for the normal operation mode.

void application_init ( void )
{
    log_cfg_t log_cfg;
    singlewirecan_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.

    singlewirecan_cfg_setup( &cfg );
    SINGLEWIRECAN_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    singlewirecan_init( &singlewirecan, &cfg );
    Delay_ms ( 100 );

    singlewirecan_set_operating_mode( &singlewirecan, SINGLEWIRECAN_OPERATING_MODE_NORMAL );
    log_info( &logger, "---- Normal Operation Mode ----" );
    Delay_ms ( 100 );
}

Application Task

Depending on the selected mode, it reads all the received data or sends the desired message every 2 seconds.

void application_task ( void )
{
#ifdef DEMO_APP_RECEIVER
    singlewirecan_process( );
#endif    
    
#ifdef DEMO_APP_TRANSMITTER
    singlewirecan_generic_write( &singlewirecan, TEXT_TO_SEND, 8 );
    log_info( &logger, "---- Data sent ----" );
    Delay_ms ( 1000 );
    Delay_ms ( 1000 );
#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.
