This paper gives an introduction about hardware connection designing and software driver designing based on FreeScale’s CPU and embedded Linux system. According to that idea, the paper designs the driver system from hardware to software. The driver system will be applied to the home wireless control system. It first introduces the theory of the touch screen, then introduces the characteristics of the AD7873. Based on the content introduced above, it designs the PCB photo of the system. It designs the soft driver which is successfully tested by the professional soft TCLIB. The results of the home smart control system are promising and convert the driver system from hardware to software under the embedded system.
