Scheme Design for Communication between Network Port and Serial Port Based on ARM

Abstract:

The data transmission scheme between a transmission control protocol/internet protocol (TCP/IP) network port and a serial port based on an ARM embedded system is introduced in the paper. The data transmission between a personal computer (PC) and remote equipment through an Internet is realized. The structure of a hardware platform is simply introduced, the cutting and transplant of operating system, the communication program design of the network port and the serial port and the cross compiling between the two ports are introduced in detail. The AT91SAM9261 chip of ATMEL Corporation is employed as the embedded board of a kernel processor. The Redhat9 Linux operating system is employed as a software development platform, an ARM-Linux operating system is employed as a program operation platform and the kernel version is Linux-2.6.2. The C program is used and an ARM-Linux-GNU tool chain is used for the cross compiling. The experimental result proves that the real-time, parallel full duplex data transmission between the network port and the serial port is realized by the scheme provided in the paper.
