基于嵌入式Linux的倒车预警系统设计

esigning an early warning system for car backing which uses an ARM cpu as the main control unit,the embedded Linux as the operating system and QT as the GUI.The system uses the Linux driver module to collect the data and QT to display the data and give the voice warning. This paper describes the design of the system’s hardware and software modules, and highlights the design of ultrasonic module,temperature compensation module,Linux driver module and the QT application.
