摘要
以温度检测及其显示为目的,研究了基于AVR单片机的智能仪器设计的控制方法。主要介绍AVR系列芯片中的ATmega162芯片特点,并将其作为主CPU,使用89C2051作为辅助CPU来采集数字温度传感器DS18B20传送出来的温度,从而实现多路温度值的采集与传送。经过ATmega162高速运算处理,实现多路温度值的数字显示和相应温度值的柱状图显示。
This paper takes the temperature examination and its demonstration as a goal, studies control method of intelligent instrument design based on the AVR MCU. It mainly introduces the characteristic of ATmega162 in the AVR series and plays a primarily CPU role,uses the 89C2051 achievement to assist CPU to gather the temperature which digital temperature sensor DS18B20 transmits,and realizes multichannel temperature value gathering and the transmitting. ATmega162's high- speed operation processing, realizes multichannel temperature value numeral demonstration and the corresponding temperature value stick plot demonstration.
