摘要
介绍了基于Atmel公司的AVR-ATmega16L单片机的污水检测的设计。该系统由前端发光二极管、光敏电阻电路,MCU处理部分(包括A/D转换、软件滤波、键盘扫描、LCD显示、DS1302实时时钟芯片时间的读取、EEPROM数据存储与读写、下位机通讯)及上位机通讯程序三大块组成。该系统所采用的时间触发嵌入式软件架构,具有普遍意义。
A detect system for residual chlorine in the water is introduced in this paper,which is designed on platform of AVR-ATmega16L MCU.Photoresistor Sensor circuit,A/D converter,keypad-scan,LED display,operation of DS1302, restore of data, communication programes are included in this system.To our notice,Time Tiggered Embedded System is used to obtain the data about degree of residual chlorine.
