摘要
采用S3C44B0X芯片作为串口通信的控制核心器件,实现了串口通信。利用MAX3232C芯片实现电平转换,S3C44B0X实现两路RS-232串口通信,并且给出了系统的硬件实现原理图。文章分析了软件实现过程:初始化串口、配置串口、发送数据和接收数据。通过实验得出该串口可以达到高效稳定的通信效果。在嵌入式系统中的串口通信技术广泛应用于基于串口通信的各种场合。
Making use of S3C44BOX chip as a serial communication control device core, it achieves serial communication. S3C44BOX carries out two group RS -232 serial port correspondence through level switch using the MAX3232C chip, and it presents hardware principle of the system. It analyzes the software details of the process ： Initializing serial port, transmitter data, etc. The experiments show that the serial port can achieve highly efficient and stable communication effects. Serial communication technology in mbedded system widely has been used in various occasions based on the serial
