摘要
Abstract
The I/O interface circuit is the important resource of single chip. It is especially used for DIP20 encapsulation AT89C2O51. In order to minimize the occupyina position of I/O of microcontroller, in the digital voltmeter designed in this paper AT89C2051 and ICL7135 are chosen as the main hardware device. Its the series connection way,simplifies the use of 20 pins of 89C2051. Its performance is deteclod in the laboratory. It shows that trie digital voltmeter has the stable, accurate advantages of data acquisition and processing, communication, panel display function.关键词
