We provide a library for the MCP2518FD Pro on Microchip page
https://www.microchip.com/develo ... uctDetails/ADM00576
as well as a demo application (example), developed using. The demo can run on all the mainboard.
Library Description
Library offers a choice to exchange messages with the other device by using CAN communication. Library also offers a choice to access a control, status and RAM registers of the device. For more details check documentation.

Key functions:
•        void MCP2518FD_transmitMessage( uint8_t numDataBytes, uint8_t *transmitFlag, uint8_t *dataIn ) - Transmits the desired message and checks is message successfully sent.
•        void MCP2518FD_receiveMessage( uint8_t *receiveFlag, uint8_t *dataOut ) - Receives the message and checks is message successfully received.
•        int8_t MCP2518FD_Configure(T_MCP2518FD_id index, T_MCP2518FD_cfg* config) - CAN Control register configuration.
•        int8_t MCP2518FD_ConfigureObjectReset(T_MCP2518FD_cfg* config) - Reset Configure object to reset values.
Examples description
The application is composed of the three sections :
•        System Initialization - Initializes peripherals and pins.
•        Application Initialization - Initializes SPI interface and performs the device configuration to work properly.
•        Application Task - (code snippet) - Always checks is new message in FIFO ready for receiving and when is message ready, receives a message from the other device. Also in this example we can sent the desired message via CAN communication to the other device. We can choose a message to be sent by sending the determined command to the UART. In this example the command, which determines a message, can be number from 1 to 7.

PI
•        UART
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.

MIKROSDK
This 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.
