5.4.2 Examples of Communications
The following provides an example of reading and writing to t UART he
communication protocol
Note: 5.4.2.1~5.4.2.6 provides an example for reading instructions,
5.4.2.7~5.4.2.9 is a write instruction to modify the power supply
and battery state, and write no memory function, and restore the
factory settings after shutdown
5.4.2.1 LAD_STATUS
Brief description: r the LED ead status
For example: t of THE LED-360DU o read the current status
Request:
R/W byte Data Length Data address bytes Data bytes CRC-8
0x55 0x03 0x00 10 0x7F
0x55 R/W byte R/W 0x55 : , decision bit, for reading instructions are
0x03 Data Length R/W : , the length of the data after the decision bit,
In this instruction , occupy a total of , so it is 0x00 10 0x7F 3 bytes
0x03
0x00 10 Data address bytes : , the address of the data to be transmitted,
0x00 10 the LAD_STATUS is address
Data bytes: The data content to be transmitted, the field for the read
instruction is empty
0x7F: Transmit data CRC-8 error detection code (including R/W byte ~
Data bytes), refer to 5.4.1.3 for the description of CRC-8, for
which the instruction is 0x7F
