如果你具有C语言编程经验并且对此较为熟悉,那么《嵌入式系统编程》第二版正是你开始学习编写嵌入式软件的入门指南。
《嵌入式系统编程》**版将这门技术教给了成千上万的人,它已成为嵌入式编程的圣经。在第二版中,我们更新了相关内容,以涵盖*新的硬件设计和开发方法论。
其中所涉及的技巧和范例代码可直接应用于真实世界里的各种嵌入式软件项目。相关例子用到了免费的GNU软件编程工具、eCos和Linux操作系统以及一种为本书特别定制的低成本硬件平台。若你获得了《嵌入式系统编程》第二版的随书工具,你将拥有一个完整的开发环境以探寻嵌入式系统中的深邃奥秘。即便你使用不同的硬件和软件,本书所提及的原理一样适用。
无论是嵌入式系统新手,还是已在嵌入式系统上做了大量工作的专业人员,你都会从本书讨论的话题中受益,它们包括:
基本调试技巧——在小巧的嵌入式系统上工作所需的关键技能
中断,和芯片内部与外围设备的监控
确定是否存在实时需求以及你的操作系统和应用程序是否能满足这些需求
在实时操作系统和嵌入式Linux中实现任务同步
优化嵌入式软件的大小、运行速度和能耗
无论你正在编写**
