S3C2416中断系统的人机交互模块设计

Design of Human-machine Interface Module Based on Interrupt System of S3C2416

介绍了一种基于S3C2416处理器中断系统的人机交互模块设计,该模块具有液晶显示、按键设置、数据通信等功能。该模块充分利用了S3C2416处理器所提供的中断资源,包括外部中断的按键、应用串口中断的数据接收以及定时器中断的闪烁显示。本模块具有软硬件成本低、开发周期短、便于移植扩展等特点,有一定的创新意义和推广价值。

In the paper,a kind of human machine interface module based on interrupt system of S3C2416 is introduced.The module has the functions of LCD display,button setting and data communication.The module fully uses the interrupt resource of S3C2416,including the external interrupt on key,the UART interrupt on data receiving,and the timer interrupt on blink display.The module has the following characteristics that has small software and hardware cost,short develop cycle,and is easy to port and extend,which has certain innovation significance and extended value.
