內容簡介
如果你具有c語言編程經驗並且對此較為熟悉，那么《嵌入式系統編程》第二版正是你開始學習編寫嵌入式軟體的入門指南。
《嵌入式系統編程》第一版將這門技術教給了成千上萬的人，它已成為嵌入式編程的聖經。在第二版中，我們更新了相關內容，以涵蓋最新的硬體設計和開發方法論。
相關例子用到了免費的gnu軟體編程工具、ecos和linux作業系統以及一種為本書特別定製的低成本硬體平台。若你獲得了《嵌入式系統編程》第二版的隨書工具，你將擁有一個完整的開發環境以探尋嵌入式系統中的深邃奧秘。即便你使用不同的硬體和軟體，本書所提及的原理一樣適用。
無論是嵌入式系統新手，還是已在嵌入式系統上做了大量工作的專業人員，你都會從本書討論的話題中受益，它們包括：
基本調試技巧——在小巧的嵌入式系統上工作所需的關鍵技能
中斷，和晶片內部與外圍設備的監控
確定是否存在實時需求以及你的作業系統和應用程式是否能滿足這些需求
在實時作業系統和嵌入式linux中實現任務同步
最佳化嵌入式軟體的大小、運行速度和能耗
無論你正在編寫第一個嵌入式程式、設計最新潮的手持的什麼東西，還是管理一群嵌入式開發工程師，《嵌入式系統編程》第二版都將幫助你提升相關知識和技能，直至你精熟嵌入式軟體。
