1. What is the DGUS?
DGUS
www.dwin.com.cn
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.
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.

1. DGUS- Data Format
For example, 4369.17 consists of 4 integers
and 2 decimals. 436917>65535. The format
should be long integer.

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

Step 3: Configuration
Interface design. Add all the images to generate configuration files via
DGUS_SDK.
www.dwin.com.cn
Step 4: Debug Test
 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.

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