Abstract: A universal design for embedded control system based on industrial ARM9 chip is
proposed. The requirement of industrial controller is analyzed, and the whole project of control system is given, and the design of A/D,D/A,CAN,USB,INTERNET and software are narrated in detail. U-boot and embedded Linux are successfully compiled and ported, which can load Linux image and root file system correctly, and establishes a dependable hardware & software platform for the application and development of embedded Linux. This control system is fitted data collection and control in industrial field, and so on.
