3. 1. What is the DGUS?
DGUS (DWIN Graphic User System) is a new GUI software platform developed by DWIN Technology. Based on the K600+ Kernel hardware platform, GUI design, combined with a simple command interface, can be achieved quickly, eliminating the need for complicated programming and expensive development environments.

4. 1. What is the DGUS?
Unlike the previous LCMs, which adopted commands-oriented or timing sequence to manage GUI, DGUS module performed based on real-time variables with programmable file configured, transmitting via UART or SD card. Software flow chart of different development methods for temperature controller is shown as above.

12. 3. Development Steps 1）Variables Scheme 2）Interface Design
3）Configuration
4）Debug Test
5）Archive

13. Step 1: Variable Scheme Two Principles
Variables addresses should be assigned continuously considering convenience of write/read;
Two
Principles
Address of parameter description variables and data variables should be separated and no cross-connect.

14. Step 2: Interface Design
Tools
Photoshop
Other graphic design software
Interface

15. Step 3: Configuration
Interface design. Add all the images to generate configuration files via DGUS_SDK.

16. Step 4: Debug Test DGUS LCM
Download DWIN_SET composed by config. file, images, font, icon library etc. to DGUS LCM via SD card for debugging and adjustment (Step 2&3)；
Connecting with use's host by serial port to process up data transmission.

17. Step 5: Archive
Config. file, images, font, icons library etc. that involved with module works were saved in an SD card for mass production.
