Read schedule of ISM 2.3Inch LED Display communication driver input 'READ' one line.

2. Writing settings

You can write the setting value by using 'writing settings'. 

Digital Write 

Digital write and analog write have the same setting parameters except output value.

Analog Write

Analog write setting parameters are as follows:

1)  PORT                   Port no. (0 ~ 255)

2)  STATION             1 ~ 99 controller station number.

3)  ADDRESS          Write value saving address(decimal unit, save at WORD, DWORD, FLOAT memory).

4)  Extra1                   Writing data type.

 H : display 'HHHH' character to LED controller,

L : display 'LLLL' character to LED controller,

etc : writing decimal number by 'output value'.

5) Extra2           Decimal point.

0, etc : auto decimal point according to output value,

1 : don't display decimal point,

2 : 1 digit decimal point,

3 : 2 digit decimal point,

4 : 3 digit decimal point.

Write example 1)

PORT:0,  station:1, ADDRESS:0000, Extra1:  ,  Extra2 : 0

The setting parameter shown above is analog write example to 1 station ISM 2.3Inch LED Display controller with auto decimal point according to output value.

Write example 2)

PORT:0,  station:1, ADDRESS:0000, Extra1:  ,  Extra2 : 2

The setting parameter shown above is analog write example to 1 station ISM 2.3Inch LED Display controller with 1 decimal point.

Write example 2)

PORT:0,  station:1, ADDRESS:0000, Extra1: H,  Extra2 : 2

The setting parameter shown above is 'HHHH' data writing example to 1 station ISM 2.3Inch LED Display controller.
