Three Typical Connections Between AT89S51 Single Chip Computer and ADC0809 Analog to Digital Converter
Yuan Zengmin · Journal of Changsha University · 2005
According to the concept that analog to digital converters are defined as external RAM of single chip computer,three typical connections between AT89S51 single chip computer and ADC0809 analog to digital converter are introduced. The characteristic of hardware and software of the three circuits are analyzed. A short program which may be used in the integrated training of interrupting,series port and analog to digital converting is given.
