There are various configurable parameters, which are shown in Section 3.2. Users can configure the CAN and UART packet frame, the size of the FIFO, or the maximum size of data area by modifying these parameters which are all defined in user_define.h.

Users can modify the definition of Custom_Element in user_define.h. Entries can be increased or decreased based on application and storage requirements.

/*user-defined information storage structure */
typedef struct {
    /*! Origin Identifier, indicating the origin of the message */
    uint32_t origin_id;
    /*! Destination Identifier, indicating the destination of the message */
    uint32_t destination_id;
    /*! Data Length Code */
    uint8_t dlc;
    /*! Data bytes */
    uint8_t data[TRANSMIT_DATA_LENGTH];
} Custom_Element;

The reception and transmission of the two communication interfaces are separated. Messages are delivered through the FIFO. Users can make changes to the structure (for example, make messages follow a specific format or even a specific communication protocol). Additionally, users can split the structure into a one-way transmission according to Figure 2-3.
