Single Wire CAN Click is a compact add-on board that contains an IC for a single wire data link capable of operating with various protocols such as the Controller Area Network (CAN). This board features the NCV7356D1R2G, Single Wire CAN transceiver from ON Semiconductor, which operates from a supply voltage from 5V to 27V with bus speed up to 40 kbps.

Single Wire CAN Click is a compact add-on board that contains an IC for a single wire data link capable of operating with various protocols such as the Controller Area Network (CAN). This board features the NCV7356D1R2G, Single Wire CAN transceiver from ON Semiconductor, which operates from a supply voltage from 5V to 27V with bus speed up to 40 kbps.
We provide a library for the SingleWireCan 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 form compilers IDE(recommended way), or downloaded from our LibStock, or found on mikroE github account.
This library contains API for SingleWireCan Click driver.
Config Object Initialization function.
void singlewirecan_cfg_setup ( singlewirecan_cfg_t *cfg );
Initialization function.
SINGLEWIRECAN_RETVAL singlewirecan_init ( singlewirecan_t ctx, singlewirecan_cfg_t cfg );
The function set desired operating mode of NCV7356 Single Wire CAN Transceiver
void singlewirecan_set_operating_mode ( singlewirecan_t *ctx, uint8_t op_mode );
This function write specified number of bytes
void singlewirecan_generic_write ( singlewirecan_t ctx, char data_buf, uint16_t len );
This function reads a desired number of data bytes.
int32_t singlewirecan_generic_read ( singlewirecan_t ctx, char data_buf, uint16_t max_len );
This example demonstrate the use of Single Wire CAN click board.
The demo application is composed of two sections :
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 );
}
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
}
The full application code, and ready to use projects can be installed directly form 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.
