Abstract:

With the improvement of the distribution network for distribution terminal facilities on visualization requirements, LCD system is widely used as the major medium of HCI (human-computer interaction). A kind of LCD control system based on AM335X is proposed in this paper, which uses modular design in hardware and consists of core control circuit, HCI module and communication interface. The system takes Windows CE 7.0 for a platform, constructs the DLL (dynamic link library) in software and adopts the multi-thread architecture in logic, to make the software simple and system stable. The experimental results show that the system runs smoothly and controls precisely, which fully meets the demands of industrial applications, to provide a reliable design scheme for the display front-end of a variety of distribution terminal facilities.
