Design asynchronous serial communication based on ARM & Linux

Zhang Hai-ya

Abstract

Serial is an important communication device in the mode of data communication.Applying the transplantable character of Linux embedded system,this paper introduces a module design of serial communication and gives the hardware circuit and the soft-ware technique of serial communication detailedly.The principal part of the hardware in this system is chiefly controlled by S3C2410x processor which is produced by SAMSUNG company,connected with the serial of computer,this system realizes the based function of visiting exterior device,which is on the based of ARM.
