CAN Isolator click provides isolated CAN communication. It carries the ADM3053 signal and power isolated CAN transceiver with an integrated isolated DC-to-DC converter. The click is designed to run on either 3.3V or 5V power supply. CAN Isolator click communicates with the target microcontroller over UART interface.

Library Description

The library covers all the necessary functions to control CAN Isolator Click board.

Key functions:

  • void canisolator_writeByte(uint8_t input) - Write Single Byte.
  • uint8_t canisolator_readByte() - Read Single Byte.
  • uint8_t canisolator_byteReady() - Check for new byte received.

Examples description

The application is composed of the three sections :

  • System Initialization - Initializes UART and LOG structures and start to write log.
  • Application Initialization - Initialization driver enables - UART, also write log.
  • Application Task - Checks if new data byte has received in RX buffer ( ready for reading ), and if ready than reads one byte from RX buffer. In the second case, the application task writes message data via UART. Results are being sent to the Usart Terminal where you can track their changes.
void applicationTask()
{
    char tmp;
    uint8_t rdyFlag;

// RECEIVER - UART polling 
    rdyFlag = canisolator_byteReady();

    if (1 == rdyFlag)
    {
        tmp = canisolator_readByte();
        mikrobus_logWrite( &tmp, _LOG_BYTE );
    }

// TRANSMITER - TX each 2 sec
/*  
    for (tmp = 0; tmp < 9; tmp++)
    {
        canisolator_writeByte( MESSAGE_DATA[tmp] );
        mikrobus_logWrite( "MESSAGE SENT", _LOG_LINE );
    }

    Delay_ms(2000);
*/
}

Additional notes and informations

Depending on the development board you are using, you may need USB UART clickUSB 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.

RS485 3V3 Click

0

RS485 Click 3.3V is a RS422/485 transceiver Click board™, which can be used as an interface between the TTL level UART and the RS422/485 communication bus. It features a half-duplex communication capability, bus Idle, open and short-circuit detection, glitch free power-up and power-down for hot-plugging applications, thermal shutdown, and more. It is well suited for transmitting data packets over long distances and noisy areas, using the twisted wire bus, which offers good electromagnetic interferences (EMI) immunity. ESD protection of the transceiver IC ensures reliable operation, exceeding 16kV for human body model (HBM).
