隨著科技日新月異瞬息萬變，短短幾年就從傳統手機進化到智慧型手機。隨著智慧型手機的飽和，下個階段是物聯網（Internet of Things， IoT），嵌入式系統也隨著興起，任何家電產品或者任何東西都可能掛上嵌入式系統，樹莓派是近年來很熱門的嵌入式平台，其價格便宜、體積小。

本論文在嵌入式系統上架構Linux系統，使用樹莓派開發板其SoC為Broadcom BCM2835，在此架構上進行研究與開發，論文中研究樹莓派核心Linux系統架構與觸控液晶螢幕裝置驅動，觸碰液晶螢幕控制IC為ILI9340，觸碰控制器IC為XPT2046使用SPI介面與樹莓派溝通。

Because the development of technology, the traditional phone evolved into smart phones in short years. The mobile phone market is gradually saturated. Internet of Things with build in embedded system becomes the new focus. Any appliances or anything that could be used in embedded systems. Raspberry Pi is a very popular embedded platforms with cheap price and small size.

This thesis researches Raspberry Pi Linux kernel architecture, LCD touch screen device driver, TFTLCD control IC ILI9340, Touch controller IC XPT2046, SPI interface to form a resistance type touch screen device. The results are promising.
