CAN FD 7 click

CAN FD 7 Click is a compact add-on board that contains a CAN transceiver that supports both CAN and CAN FD protocols. This board features the TCAN1462, an automotive fault-protected CAN FD transceiver from Texas Instruments. It is a high-speed Controller Area Network (CAN) transceiver that meets the ISO 11898-2:2016 high-speed CAN specification and the CiA 601-4 signal improvement capability (SIC) specification.

Click library

  • Author : Stefan Ilic
  • Date : Sep 2023.
  • Type : UART type

Software Support

We provide a library for the CAN FD 7 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 NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Library Description

This library contains API for CAN FD 7 Click driver.

Standard key functions :

Example key functions :

Example Description

This example writes and reads and processes data from CAN FD 7 Click.

The library also includes a function for selection of the output polarity.

The demo application is composed of two sections :

Application Init

Initializes the driver and performs the click default configuration.

void application_init ( void )
{
log_cfg_t log_cfg;
canfd7_cfg_t canfd7_cfg;
LOG_MAP_USB_UART( log_cfg );
log_init( &logger, &log_cfg );
log_info( &logger, " Application Init " );
// Click initialization.
canfd7_cfg_setup( &canfd7_cfg );
CANFD7_MAP_MIKROBUS( canfd7_cfg, MIKROBUS_1 );
if ( UART_ERROR == canfd7_init( &canfd7, &canfd7_cfg ) )
{
log_error( &logger, " Communication init." );
for ( ; ; );
}
canfd7_default_cfg ( &canfd7 );
#ifdef DEMO_APP_TRANSMITTER
log_info( &logger, "---- Transmitter mode ----" );
#else
log_info( &logger, "---- Receiver mode ----" );
#endif
log_info( &logger, " Application Task " );
}

Application Task

This example contains Transmitter/Receiver task depending on uncommented code.

Receiver logs each received byte to the UART for data logging, while the transmitter sends messages every 2 seconds.

void application_task ( void )
{
#ifdef DEMO_APP_TRANSMITTER
canfd7_generic_write( &canfd7, TX_MESSAGE, strlen( TX_MESSAGE ) );
log_info( &logger, "---- Data sent ----" );
Delay_ms( 2000 );
#else
canfd7_process( &canfd7 );
#endif
}

The full application code, and ready to use projects can be installed directly from NECTO Studio Package Manager(recommended way), downloaded from our LibStock™ or found on Mikroe github account.

Other Mikroe Libraries used in the example:

  • MikroSDK.Board
  • MikroSDK.Log
  • Click.CANFD7

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. UART terminal is available in all MikroElektronika compilers.
