摘　　要：介绍了串行通信和MAX232芯片的应用,并采用MAX232芯片制作串行接口电路,利用该电路把CPU数据读取到PC机上。在此之前,收发双方应按照约定的通信协议进行设定,以便确保单片机与PC机能正确的进行通信。在PC机上利用设置好的串行调试助手将读取的数据直观地显示出来。为进一步保证读取数据的正确性,通过示波器将串口数据波形显示出来,将两者进行对比,判断接收数据是否正确,以此来验证该串行接口电路的正确性,确保正确实现CPU与PC机之间点对点的串行通信。This paper introduces the application of serial communication and MAX232 chip. Using MAX232 chip makes serial interface circuit, and utilizing the circuit reads the CPU data of the computer. Before this, the transceiver sides must be in accordance with the agreement good communication protocol for communication. Using a serial debugging assistant makes data visually displayed in the setting PC. In order to ensure the correctness of the data, make serial port data dis- played in waveform through the oscilloscope. Comparing the two types of data, whether receiving correctly or not can verify the correctness of the serial interface circuit. Ensure the correct implementation of point-to-point serial communication be- tween CPU and the computer.
