自动化毕业设计-基于单片机的8路输入模拟信号数值显示器设计.doc

in the paper.And its software is designed secondly. Take the AT89C52 SCM and a/d

conversion chip ADC0809 as a core, this system has two parts: A/D transforms, data

processing and demonstration. Specifically includes the control, the demonstration, the

A/D switch and so on. In the design carries on 8ways with ADC0809 according to the

sampling, uses the AT89C52 SCM the serial mouth transmission and thereceive data.

Demonstrated partially constitutes by the LED numericalcode monitor. The hardware

design application electron design automation tool, the software design uses the modular

programmingmethod.
