正点原子Linux驱动 例程

1、此Makefile为个人原创，多年来从事Linux驱动开发单独编译驱动的模板Makefile，非常好用； 2、仅供参考

1, linux驱动一般分为3大类： ＊ 字符设备＊ 块设备＊ 网络设备 2, 开发环境构建： ＊ 交叉工具链构建＊ NFS和tftp服务器安装 3, 驱动开发中设计到的硬件： ＊ 数字电路知识＊ ARM硬件知识＊ 熟练使用万用表和示波器＊ 看懂芯片手册和原理图 4, linux内核源代码目录结构： ＊ arch/: arch子目录包括了所有和体系结构相关的核心代码。它的每一个子目录都代表一种支持的体系结构，例如i386就是关于intel cpu及与之相兼容体系结构的子目录。 ＊ block/: 部分块设备驱动程序； ＊ crypto: 常用加密和散列算法（如AES、SHA等），还有一些压缩和CRC校验算法； ＊ documentation/: 文档目录,没有内核代码，只是一套有用的文档；＊ drivers/: 放置系统所有的设备驱动程序；每种驱动程序又各占用一个子目录：如，/block 下为块设备驱动程序，比如ide（ide.c）。如果你希望查看所有可能包含文件系统的设备是如何初始化的，你可以看 drivers/block/genhd.c中的device_se

适用于树莓派等Debian linux的系统 包含mt7601 sta和ap两种驱动代码， 直接编译就可以使用

imx6ull嵌入式linux驱动开发指南pdf（正点原子）

该压缩包内为一本linux驱动书籍，一共23章，貌似和宋宝华的linux驱动书籍相似，可以参考下载！！

基于linux的MAX6675驱动模拟程序，主要用来读取K型热电偶信号转换成的数字信号；包含了驱动、上层测试应用程序，以及MAX6675的数据手册。

Linux Device Driver尝试着看了好几遍，总感觉理解不够透彻，很多东西经不住问，才深深的意识到，要走进浩瀚无边的Linux世界，并不是一蹴而就的事情。我决心从理论到实践，再一次走一边这本书，同时记录下自己的心得，和大家一起分享，一起讨论，一起进步。
