====== lamaPLC: TM1650 7-Segment Display with Modbus Communication ======
{{ :sensor:tm1650_modbus_2.png?120|TM1650 7-Segment Display with Modbus Communication}}

The TM1650 / STC8G IC performs the module's 7-segment control, and the TP8485E IC provides the [[com:basic_modbus|Modbus communication]] connection.

This display is a 4-digit 7-segment display with a decimal point.


  * Power supply: DC 5-36V
  * Manufacturer reference:  ‎Hyuduo5x1b64edtk1244

===== Modbus Features =====
**Modbus connection characteristics:** \\
Default Modbus settings: 9600 baud, 8N1, RTU communication, slave ID: 1

After powering up, a number, such as **"0013"**, flashes briefly. The first digit represents the slave ID (**1**), and the second indicates the baud rate (**3: 9600**).

The "write multiple registers" Modbus function (10) works, with three information (signal, number of digits, brightness) (2.468 / low brightness 1: //TX 01 10 00 00 00 03 06 09 a4 00 03 00 01 a6 00//)

The registers must be written one at a time using the "write single register" function (6). (Send 1234: //TX: 01 06 00 00 04 d2 0b 57//)
