Abstract

In order to upgrade the stepping motor controller

the application of S3C2440A in human-computer interaction of stepping motor controller was discussed in detail. The special touch-screen interface and LCD controller in S3C2440A could connect with touch-screen and LCD directly. Based on introducing the architecture of stepping motor controller

circuits among S3C2440A

touch-screen and LCD were given

and related application programming design was analyzed deeply. The information of touched point on touch-screen was sampled by combining interrupting mode and

X/Y

coordinate sequential conversion mode

meanwhile three-points calibration method was introduced. At last

sampling codes were given. The scheduling

buffer setting and displaying data format of LCD controller were analyzed based on 320240 TFT LCD. Also

the applied programming codes were given. At last

the above codes were executed in practical system. Result shows that connection between S3C2440A

touch screen and LCD is convenient. So the hardware-design and load of the system could be predigested with this architecture. This system runs well in the application.
