Ad Sampling Experiment Based on Mcu

Abstract

The A/D sampling experiment in digital electrical experiment teaching is limited by hardware conditions and complexity, so the practical education often cannot carry out the problem. The single chip microcomputer technology and several electric technology combined with each other, constructs the sampling data width of 8 bit microcontroller, 200 KHZ sampling rate of A/D sampling analog chips. Set up a simple peripheral circuit can be analog sampling numerical digital tube display. In addition, the simulator can simulate any 74 logic chip of DIP16 package size. The chip simulator can let students understand the sampling rate, the parameters such as linearity, at the same time can make students master microcontroller programming language.
