As listed in Table 4.8, the frame information (0x08) of the CAN message is converted
to the first byte (0x08) in the serial frame, and the ID 0x0123 in the CAN message is
converted to the second byte (0x01) and the third byte (0x23) in the serial frame. The data
field of the CAN message will be converted into the data part of the serial frame without
any modification.
4. Converting CANFD messages to serial frames
The CAN type configured in this example is CANFD, and the conversion of "frame
information" and "frame ID" of the message is enabled. Assuming that the frame ID1 in the
CANFD message is 0x01, the frame ID0 is 0x23, and the data is 0x01-0x40, a total of 64
data. Table 4.9 lists the CANFD message and the converted serial frame .
