Instruction example and detailed explanation
0. Display data (00 32 decimal is 50, and negative numbers are represented by the inverse code. If ff fe is sent, it will display -001) Address: 0x01 Function: 0x06 Register address high: 0x00 Register address low: 0x00 Data high: 0x00 Data low: 0x32 CRC check: 0x08 / 01F Slave response Address: 0x01 Function: 0x06 Register address high: 0x00 Register address low: 0x00 Data high: 0x00 Data low: 0x32 CRC check: 0x08 / 0x1f
1. Set the position of the decimal point (the range is 01-03, 01 is the decimal point after the tens digit, 02 is the decimal point after the hundreds digit, 03 is the thousand digit, and only the tens and hundreds digit after the negative number can be displayed)
