Serial Communication of the Embedded System Based on S3C44BOX

Making use of S3C44B0X chip as a serial communication control device core,it achieves serial communication.S3C44B0X 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 communication.
