4.1.3 Conversion Examples
1. Serial frames to CAN messages
Suppose the CAN type is ordinary CAN, the frame information is "standard frame",
the frame ID1 and ID0 are "0x01, 0x23" respectively, the serial frame data is 0x01-0x0C,
the conversion format is listed in Table 4.6. The frame ID of the CAN message is 0x0123
(user configuration), the frame information is a standard frame (user configuration), and
the data part in the serial frame will be converted into the CAN message without any
modification.
