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?

www.dwin.com.cn

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.

Two

Principles

Two

Principles

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.

Interface design. Add all the images to generate configuration files via DGUS_SDK.

Step 3: Configuration

www.dwin.com.cn

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.

How to communicate?

Data Frame: Frame of data via serial are composed by 4 parts of data

Length 2 1 1 N 2

Note Definition of R3:RA in CONFIG.TXT

Length included command, data and

CONFIG.TXT determine if R2 in configuration file are started

Both commands or data are hexadecimal. As for word(2 bytes), high byte in priority is transferred （ MSB ）
