| 摘 要： | 介绍了一种基于可编程数字电位器来改变放大器增益,并通过ATmega16单片机进行控制的模拟信号测量系统。利用了ATmega16自带的10位逐次逼近型A/D模块进行模数转换,并送往外接的LCD1602进行显示,有效地实现了对测量的模拟信号可控放大,信号转换和输出显示。利用ATmega16单片机自带的EEPROM单元实现对数据的记录,从而提供了对测量信号的回显功能。同时,对系统的整体功能设计、硬件电路和软件设计进行了详细的阐述。

| Abstract: | A kind of based on programmable digital potentionmeter to change amplifier,and through the ATmega16 single-chip microcomputer control simulation signal measuring system.It used 10-bit successive approximation A/D module of the ATmega16 to analog-to-digital conversion,and sent to the extemal LCD1602 to display,effectively realized measuring signal of controlllable amplifier,signal conversion and the output display.And by using single chip ATmega16 EEPROM to make the data ecord,it provides the signal to the back to show function.It described the overall function of the system design,hardware circuit and software design in detail. |
