Example of CAN message conversion to serial frame (transparent with information conversion)
4.1.3 Protocol mode
The fixed 13 bytes of CAN format conversion represent a CAN frame data, and the content of 13 bytes includes CAN
frame infor frame ID + frame data. In this conversion mode, the CANID set is invalid, because the identifier
(frame ID) sent at this time is filled with the frame ID data in the serial frame of the above format. The configured frame
type is also invalid. The frame type is determined by the frame information in the format serial frame. The format is as
follows:
CAN fixed format serial frame (13 bytes)
