KinCony TS Tiny sensor PC software and modbus protocol

[admin]

Modbus protocol:

A. input register function:

temperature : 16bit unsigned integer register
humidity: 16bit unsigned integer register

address    function
0000H        temperature value
            unit: ℃
            fixed 1 decimal
            (1) >0℃: register data<10000
                          for example: register value=250, actual temperature: 250*0.1=25℃
            (2) <0℃: register data>=10000
                          for example: register value=10250, actual temperature: -1*(10250-10000)*0.1=25℃
------------------------------------
0001H        humidity value
            unit: %RH
            fixed 1 decimal
                          for example: register value=500, actual humidity: 500*0.1=50(%RH)
------------------------------------
0002H        temperature value
0003H        unit: ℃  decode: 32bit float data
------------------------------------
0004H        humidity value
0005H        unit: %RH  decode: 32bit float data


B. Hold register function:
The contents of the register are saved when power is turned off. The holding register is a readable and writable register. The value in each register is a 16-bit unsigned integer.

address    function
0000H        temperature value
            unit: ℃
            fixed 1 decimal
            (1) >0℃: register data<10000
                          for example: register value=250, actual temperature: 250*0.1=25℃
            (2) <0℃: register data>=10000
                          for example: register value=10250, actual temperature: -1*(10250-10000)*0.1=25℃
------------------------------------
0001H        humidity value
            unit: %RH
            fixed 1 decimal
                          for example: register value=500, actual humidity: 500*0.1=50(%RH)
------------------------------------
0002H        temperature value
0003H        unit: ℃  decode: 32bit float data
------------------------------------
0004H        humidity value
0005H        unit: %RH  decode: 32bit float data
------------------------------------
000AH        RS485 bus address(1-255), default:1 
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.
------------------------------------
000BH        Baud rate setting:
            0:4800  1:9600(default) 2:14400 3:19200 4:38400 5:56000 6:57600 7:115200
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.
------------------------------------
003DH        Parity settings
            0:None(default)  1:odd parity 2:even parity
            Note: This parameter is saved after power-off and will take effect after power-on again after modification.

modify RS485 setting command:

register:
1001：SLAVE address 1-250
1002：Baud rate: baud_arr[8] = {4800,9600,14400,19200,38400,56000,57600,115200}
1003: Parity bit: parity_arr[3] = {UART_PARITY_NONE,UART_PARITY_EVEN,UART_PARITY_ODD}


how to remember RS485 address if you forget it.
1: every time power on will output board information by RS485 (9600,8,N,1) if you forget the board's address.
2: hold on button > 2 seconds, will reset to factory setting, default RS485 address=1
