摘要
以MSC-51单片机为核心,结合温度传感器、模数转换器件ADC0809设计温度采集控制系统。利用单片机的内部中断源产生中断,处理采集到的数据,并能实现定时刷新。系统功能均由按键控制实现,测量结果实时显示,可节省CPU资源且有效地提高CPU的利用率。
This paper designs a temperature acquisition and control system,which consists of MSC-51 single chip as the core components, and temperature sensors, A/D chip ADC0809. Using the internal interrupt sources of single-chip to make an interrupt, thus dealing with the collected data and get the purpose to refresh the data at certain times. System functions are realized through the button control, the measurement results are displayed in real-time,which saves CPU resources and effectively improves the utilization of the CPU.
