摘要
介绍了传统采用单片机控制的LED显示屏的设计方法与基于PSoC技术的LED显示屏的设计方法的区别;阐述了PSoC技术在LED点阵显示系统设计中的优势;以PSoC系列的CY8C27443芯片为核心的LED点阵显示系统为例,具体描述了PSoC多功能精简尺寸型LED点阵系统的硬件设计、PSoC配置和软件功能的具体设计实现方法。由于CY8C27443芯片的内部资源更加丰富所以进行LED点阵系统的设计比51单片机电路更加简单,性能更加稳定,软件设计也更加简单方便,所以大大节省了开发周期和成本。
This paper introduces the traditional using single chip microcomputer control LED and displays design methods based on PSoC technology with the LED display design different methods. It expounds the PSoC technology in the design of LED dot matrix and displays system advantages. It takes PSoC series CY8C27443 chips as the core of LED dot matrix display system for example and Describes PSoC Multi-functional concise type size of LED dot matrix system hardware configuration and software design and PSoC function of the specific design method. Because of the CY8C27443 chip internal resources are much rich so the design of LED dot matrix system than 51MCU circuit is not only simple and stable performance but also easy in the software design. Therefore, this system can save the developing cycle and cost.
