摘要
利用芯片ADC0808进行AD转换已广泛应用于很多领域,极大地方便了人们的工作和生活。本文以可调电阻作为模拟量输入,经转换器接口芯片ADC0808完成数据转换,AT89C52单片机为控制器,对转换后得到的数字量经单片机P1口送LED显示器输出。文中使用到的编程软件是KEIL C软件,利用Proteus软件仿真AD转换并显示转换结果,仿真效果良好,能够满足实际应用要求。
The function of AD conversion by using ADC0808 chip has been widely used in many fields and has greatly facilitated people＇s work and life. Analog data of tunable resistor is converted into the digital data by using AIJC0808 chip, micrechip AT89C52 is used as main controller, the conversion result is output through P1 port of the microchip and is displayed by using the LED device. In this design, KEIL C is used as the programming software, AD conversion simulation is through using the Proteus software, the effect of the simulation result is nice and can meet the requirement of practical application.
