1、基于 ARM 的应用开发LCD 显示波形 I 摘要摘要 随着现代计算机技术的飞速发展和互联网技术的广泛应用,从 PC 时代过渡到了以 个人数字处理、手持个人电脑和信息家电为代表的 3C(计算机、通信、消费电子)一体 的后 PC 时代。后 PC 时代里,嵌入式系统扮演了越来越重要的角色,被广泛应用于信息 电器、移动设备、网络设备和工控仿真等领域。 本文讨论了基于 ARM 微处理器和嵌入式系统的应用开发,主要以波形采集、LCD 显示和嵌入式系统 C/OS-II 为主要研究对象。描述了三星 S3C44B0X 微处理器及 C/OS-II 实时操作系统的特点,搭建了一个以 S3C44B0X 处理器为核心
2、的通用嵌入式系 统平台,并在此平台基础上实现了 LCD 显示波形、GUI 绘图、多任务系统等典型应用。 对 ARM 微处理器和嵌入式系统的进一步教学和研究开发有一定的指导价值。 关键词:关键词:ARM 微处理器 嵌入式系统 C/OS-II GUI 绘图 多任务系统 基于 ARM 的应用开发LCD 显示波形 II Based on ARM Applications DevelopmentLCD Show Waveform Abstract With the development of the modern computer technology and the widely applicati
3、on of the Internet technology, We transited from the PC time to the latter PC time which is taking individual digital processing,grasping the personal computing and the information electrical appliances as representatives 3C (computer, correspondence, expense electron) a body .In the latter PC time,
4、 the inserted type system which acts the more and more important role, is widely applied in the information electric appliance, the mobile equipment, the network equipment and the labor controls domain and so on. This article discussed the application development based on the inserted type system and the ARM microprocessor, mainly by profile gathering, LCD demonstrated and the inserted type system C/OS-II is the main research object. Described the Sumsang S3C44B0X microprocessor and The
