Convert serial frame into CAN message (transparent mode)
2. CAN message to serial frame
During the conversion, all the data in the CAN message data field are sequentially converted into the serial frame. If you
check "Enable Frame Information" during configuration, the module will directly fill the "Frame Information" byte of the
CAN message into the serial frame. If you check "Enable Frame ID", then all the "Frame ID" bytes of the CAN message
are also filled into the serial frame.
Note: If you want to receive CAN frame information or frame ID on the serial interface, you need to enable the
corresponding function. Only then can you receive the corresponding information.
