Abstract：This paper first introduces embedded system profiles as well as embedded systems applications in today’s society, followed by a brief introduction to the characteristics of Linux , and Linux, and then describes some of the knowledge of the system structure of the S3C2440 and ARM9 development board, LCD display as well as the type of TFT LCD display principle and driving principle, then the knowledge of the GPRS module GPRS applications and works, citing some common SIM300 AT Command Set. Then began to build a PC Linux development environment, followed by the development board environment to build, And then it began the preparation of project procedures and compile followed on the part of the program, listed at the end of the project to achieve the effect.
Key word: Linux; S3C2440; GPRS; TFT LCD; AT instruction module
