The driver realization of the 16 gray LCD based upon the μCLinux system
Abstract:In this paper, based on S3C44B0X LCD controller driver μCLinux design and implementation, are discussed in the embedded μCLinux mechanism-based LCD frame buffer driver implementation methods. The main studied μCLinux frame buffer device driver framework, a detailed analysis of the frame buffer device driver hierarchy, the core of functional modules and data structures, design of the framebuffer the treatment mechanism as well as the underlying driver of the interface function of the LCD panel-specific how to embed Type μCLinux in the preparation of frame buffer device driver.
Keywords: S3C44B0X device driver, LCD controller, frame buffer
