4.5 Transparent tape identification conversion
Transparent tape identification conversion is a special use of transparent conversion without any protocol
attached. This conversion method is based on the common characteristics of the usual serial frame and CAN message,
so that the two different bus types can easily form a same communication network.
In this mode, the CAN bus receiver can add the received frame information of the CAN message and the frame
ID to the converted serial frame. In this way, the receiver can clearly see the sender's CAN message to ensure more
flexible use.
4.5.1 Frames in UART converts to CAN message
With the transparent conversion, all the data of the serial frame is sequentially filled into the data field of the
CAN message frame. The converter receives and converts as soon as it detects that there is data on the serial bus.
The frame type and frame ID of the converted CAN message come from the user's prior configuration, and the
frame type and frame ID remain unchanged during the conversion process. The corresponding format of data
conversion is shown in Figure 4.1.
If the received serial frame length is less than or equal to 8 bytes, the characters 1 to n (n is the serial frame
