商品描述: 导语摘要
是否有兴趣开发嵌入式系统？这些系统无法容忍低下的效率，它们需要遵循严格的方式进行编程。《嵌入式系统开发(影印版)》这本易于阅读的指南通过经典的软件设计模式和嵌入式编程的全新模式来帮助你培养许多良好的开发习惯。你会学习到如何为处理器而不是操作系统来搭建系统架构，并且了解到处理硬件问题和制造工艺所需的特殊技术。
这本书的作者创建过各种各样的嵌入式系统，从城市监控和DNA扫描仪到儿童玩具。本书适合于中等和有经验的编程人员，无论你使用的是什么平台。本书由怀特(White,E.)著。

作者简介
EleciaWhite是LogicalElegance，一家在圣何塞的嵌入式系统咨询公司的创办人。她喜欢制作有趣的玩意，包括医学设备、惯性测量装置、教育玩具和一套枪声定位系统。
