The Single Wire CAN Click Board™ is based on the NCV7356D1R2G, a Single Wire CAN transceiver from ON Semiconductor, which operates from a supply voltage from 5V to 27V with a bus speed up to 40 kbps. It can access several modes such as Normal Mode with reduced dominant output voltage and reduced receiver input voltage, High-Speed, High Voltage Wake-Up, or Sleep Mode. The transmission bit rate in Normal communication is 33 Kbits/s, while a typical bit rate of 83 kbit/s is recommended for High-Speed communication. In Normal Transmission Mode, the Single Wire CAN Click supports controlled waveform rise and overshoot times, while the High−Speed Mode is only intended to be operational when the bus is attached to an off−board service node.
The Single Wire CAN Click Board™ pin CANH is composed of a pull−up amplifier for driving this Click board™. The minimum output driver capability is 50 mA, but output shorts to the ground can reach 350mA. Normal CANH output voltage is between 4.4 V and 5.1 V. These amplitudes increase to between 9.9 V and 12.5 V for system selection in Wake−Up Mode. The bus Wake−Up from Sleep Input Voltage Threshold is between 6.6 V and 7.9 V, but to maintain normal communication, the threshold is 2.1 V. The CANH pin can also act as a bus read amplifier.
The NCV7356D1R2G communicates with MCU using the UART interface at 9600 bps with commonly used UART RX and TX pins. It possesses additional functionality such as Operational Mode Selection MODE 0 and MODE 1 routed at RST and CS pins of the mikroBUS™, on whose selected logical states one of the four possible operational modes can be selected. The transceiver provides a weak internal pulldown current on each of these pins which causes the transceiver on default to enters to sleep mode when they are not driven. Single Wire CAN Click can also re-enter the Sleep Mode if there is no mode change within typically 250 ms.
The Single Wire CAN Click Board™ communicates with MCU using the UART interface for the data transfer. The onboard SMD jumper labelled as VCC SEL allows logic level voltage selection for interfacing with both 3.3V and 5V MCUs. More information about the NCV7356D1R2G's functionality, electrical specifications, and typical performance can be found in the attached datasheet. However, the Click board™ comes equipped with a library that contains easy to use functions and a usage example that may be used as a reference for the development.

We provide a library for the Single Wire CAN Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
The library covers all the necessary functions to control the Single Wire CAN Click Board™. Library performs a standard UART interface communication.
void singlewirecan_set_operating_mode ( uint8_t op_mode ) - Set operating mode function.void singlewirecan_write_data ( uint8_t *tx_data ) - Write multi bytes function.The application is composed of three sections :
void application_task ( )
{
mikrobus_logWrite( "----------------------", _LOG_LINE );
mikrobus_logWrite( "", _LOG_LINE );
singlewirecan_write_data( &demo_message_data[ 0 ] );
mikrobus_logWrite( " TX Data: ", _LOG_TEXT );
mikrobus_logWrite( demo_message_data, _LOG_LINE );
Delay_ms( 3000 );
}
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
Depending on the development board you are using, you may need a 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.
The Single Wire CAN Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.

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. It supports many additional features like an under-voltage lockout, a timeout for faulty blocked input signals, output blanking time in case of bus ringing, and a very low sleep mode current. This Click Board™ can be used in industrial equipment, in-vehicle, and industrial networking, and in applications where the high data rate is not required and a lower data rate can achieve cost reductions.
The Single Wire CAN Click is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
