基于PSoC 3的传感器教学实验平台研制

Development of sensor teaching experimental platform based on PSoC 3

结合传感器实验课程,研制了一款基于PSoC 3(programmable system-On-Chip 3,片上可编程系统)的传感器实验平台。该实验平台以美国Cypress公司生产的PSoC 3为核心,根据PSoC 3所集成的微控制器以及嵌入式系统中常用的模拟、数字等优点,实现了传感器实验中的温度、光电、霍尔以及其他常用传感器的数据采集与处理,并通过USB2.0与基于LabVIEW设计的上位机软件进行数据交互与处理。该平台体积小、功能强大,配有外部扩展用的通用接口(GPIO)和可编程差分放大接口(SIO)。该实验平台除了可以开设传统实验外,还可以进行自主实验和拓展创新实验。

Combined with sensor experiment in universities curriculum,a sensor experimental platform based on PSoC 3（Programmable System-On-Chip 3）is developed.The experimental platform works around the PSoC 3produced by United States Cypress Company as the core.With the microcontrollers integrated by PSoC3 and the advantages commonly used in embedded systems such as analog,digital and so on,the experimental platform realizes the data acquisition and processing of the temperature,photoelectric,Hall and other common sensors used in sensor experiments,and carries out data exchange and processing with PC software designed based on LabVIEW via USB2.0.The platform is small and powerful,with general purpose input output（GPIO）and programmable differential amplifier super input output（SIO）for external expansion.Beside setting up traditional experiment,the platform also can be used for independent and developed innovative experiments.
