1. DGUS_SDK Instruction
1.1 Operation of DGUS_SDK
(1) DGUS (DWIN Graphical Utility Software) is an intelligent GUI design software for DWIN DGUS LCM with K600+ kernel. As
be helpful to interface of display design faster than ever, diversified display effects can be achieved easily and rapidly with much less
programming. The variables in use are defined by software DGUS_SDK v5.1 that is accessed by controller via address. All
parameters and images can be downloaded via SD card which stores related .bin files to make your design into real application.
(2) Install DGUS_SDK_V5.1:
Unzip DGUS_SDK_V5.1.zip, and click DGUS ToolV5.1.exe to run it.
(.net Framework 2.0 is required to run the software).
(3) Variable Definition
VP (Variable Pointer): The addresses of variables in variable SRAM (56KB). Users can set buttons with defined VP,
to change the value in this address and display contents corresponding with the value in VP address.
SP (Stack Pointer): the address of definitions, starting address of description data of variables. Change the value in
particular address to modify variable properties. Take <WordArt> function as example.
Add. Definition Data
Length Description
0x00 0x5A03 2
0x02 *SP 2 Stack pointer, default setting is 0xFFFF.
0x04 0x0007 2 The whole process length (in terms of words).
0x06 0x00 *VP 2 Variable pointer.
0x08 0x01 X,Y 4 Top-left coordinate of text, left aligned.
0x0C 0x03 Icon0 2 Icon ID corresponding to 0, the sequence is “0123456789-.”.
0x0E 0x04:H Icon_Lib 1 Address of icon file.
0x0F 0x04:L Icon_Mode 1 ICON display mode.
0x00: transparent, others: opaque.
0x10 0x05:H Int_Num 1 Length of integer digits.
0x11 0x05:L Dec_Num 1 Length of decimal digits.
0x12 0x06:H VP_Data_Mode 1 0x00: integer (2 bytes), 0x01: long integer (4 bytes).
E.g.: If SP valued as 0x5000 for WordArt variable, VP parameter will be saved in the ADDRESS of 0x5000. Variable position
parameters will be saved in 0x5001-0x5002
(4) If you need to handle with icons, please drop icon files into Icon Generator to make icon file running in DGUS correctly.
(5) How to select area for buttons & variables.
A. Input coordinates directly.
or
B. Drag the button/variable with mouse.
(6) Define SP address for variables.
Professional,Creditable,Successful DGUS_SDK User Guide V5.1
Beijing DWIN Technology Co., Ltd. 5 www.dwin.com.cn
SP defines the description of variable settings; to reduce overlap of SP address is necessary. There is overlap judging
embedded, Configuration files won’t be created with failure message when it comes an overlap of SP address.
(7) Import existing DGUS config. files into new project.
A. Create a new project.
B. Add pictures.
C. Import config files.
D. Copy icon files into <DWIN_SET> folder.
Note: Frame header is self-defined by users. In this document, A5 5A is taken as frame header for instance.

4.4 VP & SP
4.4.1 VP (Variable Pointer)
4.4.1.1 About VP
VP is the initial address of variables in variable SRAM (56KB) which separated into 28672 pcs of memory spaces from 0x0000
to 0x6FFF occupying two bytes for each below. (High bytes and Low bytes)
The communication between DGUS LCMs and host is oriented by variables that you may read or write in corresponding
address. Reading &Writing of initial address and variable length could be changed via Command 0x82&0X83 if known in advance.
4.4.1.2 How to use VP?
Assign VP for each variables
Each variable should be assigned a VP, yet overlap is not allowed. The value of the variable will be saved from the VP. For
example, variable 1 as a long integer saved in 0x1001 while variable 2 as an integer have to be stored on another address
preventing 0x1001 and 0x1002 from conflicts with variable 1.

For example, display and input a variable (No. 100) which is an integer. The VP of this variable is 0x1000.

Supposing that reading & writing to the same one, touch and input parameters of VP should be the same accordingly.
4.4.2 SP (Stack Pointer)
4.4.2.1 About SP
SP is the initial address for saving variable attributes which described features of the variables, such as font color, font size and
unit of variables, etc. The variable attributes refers to the Chapter Five of DGUS Dev. Guide.
SP shares the same SRAM with VP from 0x0000 to 0x6FFF. It is only used for variable display but overlap exception.

Change variable attributes via SP
Same sample as above：
In operation, if user attempts to do the changes on data color to red, just need able to write down a new value into
corresponding address.
Frame header (2 Bytes)+Data length (1 Byte)+Command (1 Byte)+Data (N Byte: ADR+data/LEN)+CRC (2 Bytes, optional)
Send:5A A5 05 82 50 03 F8 00

F800: the value of red color
4.5 Examples
Configure frame header and baud rate in CONFIG.TXT via DGUS SDK as below:
R1=07
R3=5A
RA=A5
Frame header (2 Bytes)+Data length (1 Byte)+Command (1 Byte)+Data (N Byte: ADR+data/LEN)+CRC (2
