CAN Bus Click is a compact add-on board that provides a link between the CAN protocol controller and the physical wires of the bus lines in a control area network (CAN). This board features the MAX13054, an industry-standard, high-speed CAN transceiver with extended ±80V fault protection from Maxim Integrated.

CAN Bus Click is a compact add-on board that provides a link between the CAN protocol controller and the physical wires of the bus lines in a control area network (CAN). This board features the MAX13054, an industry-standard, high-speed CAN transceiver with extended ±80V fault protection from Maxim Integrated.
We provide a library for the CanBus 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.
This library contains API for CanBus Click driver.
canbus_cfg_setup
Config Object Initialization function.
void canbus_cfg_setup ( canbus_cfg_t *cfg );
canbus_init
Initialization function.
CANBUS_RETVAL canbus_init ( canbus_t *ctx, canbus_cfg_t *cfg );
canbus_default_cfg
Click Default Configuration function.
void canbus_default_cfg ( canbus_t *ctx );
canbus_send_data
CAN Bus send data function.
err_t canbus_send_data ( canbus_t *ctx, char *tx_data );
canbus_set_high_speed_mode
CAN Bus high speed mode function.
err_t canbus_set_high_speed_mode ( canbus_t *ctx );
canbus_set_low_current_standby_mode
CAN Bus low current standby mode function.
err_t canbus_set_low_current_standby_mode ( canbus_t *ctx );
This library contains API for CAN Bus Click board™. This example transmits/receives and processes data from CAN Bus Click. The library initializes and defines the UART bus drivers to transmit or receive data.
The demo application is composed of two sections :
Initializes driver, wake-up module, and set high-speed operation mode.
void application_init ( void ) {
log_cfg_t log_cfg; /**< Logger config object. */
canbus_cfg_t canbus_cfg; /**< Click config object. */
/**
* 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.

Transmitter/Receiver task depends on uncommented code. Receiver logging each received byte to the UART for data logging, while transmitted send messages every 2 seconds.

canbus_process( );
if ( app_buf_len > 0 ) {
log_printf( &logger, "%s", app_buf );
canbus_clear_app_buf( );
}
#endif
}
canbus_clear_app_buf
Function clears memory of app_buf.
static void canbus_clear_app_buf ( void );
canbus_process
The general process of collecting presponce that a module sends.
static err_t canbus_process ( void );
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.

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.
