| 摘 要： | 触摸屏作为人机界面应用于气相色谱仪控制系统．在彩色LCD的配合下可实现可视化控制。本系统是基于S3C4480嵌入式开发平台，但是此处理器无SPI总线接口寄存器．只能通过软件模拟SPI，实现与ADS7846通信。文中给出了触摸屏数据采集的流程和用C语言实现的模拟SPI通信程序。

| Abstract: | The touch screen is introduced as the human-machine interface to the control of gas chromatography, and the visual control is realized with color LCD. This paper uses software to simulate the SPI bus time sequence to communicate between general I/O and ADS7846,due to no SPI interface on the embed platform of S3C44B0. We introduce the flowchart of data collection from touch screen and the programs with C language. |
