measured voltage through the ADC ADC0809 analog to digital conversion, to achieve the collected data to digital

analog conversion, the converted data through the serial port MAX232 transmitted to the host computer, the host

computer responsible for data receiving, processing and display, and LED digital display to display the collected

results. Part of the application software written in VB control software, data acquisition systems, analog to digital

conversion system, data display, data communications and other procedures were designed. After commissioning

the design of the data acquisition, analog to digital conversion, display and PC graphics functions.
