CAN FD4 Click

CAN FD 4 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 : Jun 2020.
  • Type : UART type

Software Support

Example Description

This example reads and processes data from CAN FD 4 Clicks.

Example Libraries

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.CanFd4

Example Key Functions

  • canfd4_cfg_setup Config Object Initialization function.
void canfd4_cfg_setup ( canfd4_cfg_t *cfg );
  • canfd4_init Initialization function.
err_t canfd4_init ( canfd4_t *ctx, canfd4_cfg_t *cfg );
  • canfd4_generic_write Generic write function.
void canfd4_generic_write ( canfd4_t *ctx, char *data_buf, uint16_t len );
  • canfd4_set_dev_mode Set mode function.
void canfd4_set_dev_mode ( canfd4_t *ctx, uint8_t mode );
  • canfd4_generic_read Generic read function.
int32_t canfd4_generic_read ( canfd4_t *ctx, char *data_buf, uint16_t max_len );

Application Init

Initializes the driver and enables the Click board.

void application_init ( void )
{
    log_cfg_t log_cfg;
    canfd4_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.

    canfd4_cfg_setup( &cfg );
    CANFD4_MAP_MIKROBUS( cfg, MIKROBUS_1 );
    canfd4_init( &canfd4, &cfg );

    canfd4_set_dev_mode ( &canfd4, CANFD4_NORMAL_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
    canfd4_process( );
#endif
#ifdef DEMO_APP_TRANSMITTER
    canfd4_generic_write( &canfd4, TEXT_TO_SEND, 8 );
    log_info( &logger, "--- The message is 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.
