摘要
给出了以AT89C2051为核心 ,利用单片机的运算和控制功能 ,并采用串口液晶显示模块实时显示所测速度和里程的速度里程表设计方案。该方案由于使用了串口液晶显示模块和E2PROM ,以及高效快速算法 。
In this paper,a speed odometer based on processor AT89C2051is designed.By making full use of single chip's ability to calculate and control,speed and mileage can be displayed instantly on liquid crystal disˉplay with serial data transfer.It can economize systemresources and cut short programme and then can meet the needs of high accuracy and short measuring time.
