The Design and Implementation of Interactive HMI based on Bluetooth Technology

The response time and limited resources in embedded system graphic interactive interface is not a small risk. This paper describes an implementation based on Philips ARM7TDMI LPC2104 microcontroller and lightweight Bluetooth interactive graphical interface. The paper indicates from the hardware design, software application development two aspects and puts forward a graphical interface based on Bluetooth technology system implementation process, comparing the different systems of other graphic design features. GUI of light-weight, high performance, high reliability and good operability is in urgent need in the industrial real-time control system design. This paper introduces an implementation method of lightweight Bluetooth interactive graphic interface based on Philips ARM7TDMI LPC2104 micro controller, 130* 130 resolution color LCD control module, BGB203 Bluetooth module and other hardware constructions. It has also put forward the implementation procedure of graphic interface system based on Bluetooth technology and its characteristics compared with other graphic interface systems from the aspects of hardware design and software program development.
