The communication interface design of AT89C51 preparation robot based on Serial

摘要

This paper presents a MAX232 chip using AT89C51 Microcontroller to RS-232 Serial Communication, And RS-232 communication interface design can give about preparation robot of Xi'an Aeronautical College. Finally, giving the MAX232 chip test program. Through practice we proved that the program can meet the practical needs with low cost, anti-interference ability, and reliable performance.
