Communication Protocol Description:
1. This module has the function of communicating with computer. Can facilitate the computer to read the module current and voltage data,
2. The communication protocol is as follows:
Baud rate: 9600 Bps
BB CC ADDR 00 XX XX CRC (Current Return Command)
BB CC ADDR 01 XX XX CRC (voltage return command)
among them
BB CC for the first frame (2 bytes)
ADDR is the module address (1 byte)
00 for reading current command (1 byte)
01 for reading voltage command (1 byte)
XX XX any value (2 bytes)
CRC CRC check (1 byte)
