The CAN FD 4 Click is a Click board™ that features the NCV7344D10R2G, a Controller Area Network (CAN) transceiver, from ON Semiconductor.
We provide a library for the CanFd4 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 from compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for CanFd4 Click driver.
Config Object Initialization function.
void canfd4_cfg_setup ( canfd4_cfg_t *cfg );
Initialization function.
CANFD4_RETVAL canfd4_init ( canfd4_t ctx, canfd4_cfg_t cfg );
Generic write function.
void canfd4_generic_write ( canfd4_t ctx, char data_buf, uint16_t len );
Set mode function.
void canfd4_set_dev_mode ( canfd4_t *ctx, uint8_t mode );
Generic read function.
int32_t canfd4_generic_read ( canfd4_t ctx, char data_buf, uint16_t max_len );
This example reads and processes data from CAN FD 4 clicks.
The demo application is composed of two sections :
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 );
}
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
}
The full application code, and ready to use projects can be installed directly from compilers IDE(recommneded) or found on LibStock page or mikroE GitHub accaunt.

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.
