Description: 利用framebuffer画小企鹅
Linux的framebuffer接口提供给用户访问显示设备的通用接口，通过mmap映射显示缓冲给用户，fb中我们设置什么值，将直接在屏幕上显示出来。本实验我们要利用framebuffer在屏幕上显示一个小企鹅，可以接读取bmp图片,设置framebuffer的值，或者利用include/linux/linux_logo.h文件（该文件已经定义好小企鹅的颜色和位置信息），设置framebuffer的值。本实验采用的是第二种方法。只要读取linux_logo.h中数组的值，进行相应的移位操作，将值赋给fb即可在屏幕上显示出小企鹅 。-Framebuffer draw using the framebuffer Little Penguin Linux interface to the user access to the display device of the common interface, through mmap mapped display buffer to the user, fb set up what we value, will be directly displayed on the screen. This experiment we want to use framebuffer on the screen, a small penguin, you can then read bmp images, set up framebuffer value, or the use of include/linux/linux_logo.h file (the file has the definition of a good little penguins color and location information) , set the value of framebuffer. Used in this experiment is the second method. Linux_logo.h read in as long as the value of the array, the corresponding shift operation, the value assigned to fb can be displayed on the screen small penguins.

Description: 这些是对(用 )于 书的来源文件" Linux Device Drivers" 。
在这里你(们)找到已经包括在书里的完全来源。 我尽可能地测试了他们, 但是, 可以(可能)有一些问题离开了, 尤其有 2.1.43 (当位于下面代码基础(底模)(是)连续不断变化时, 可靠性测试所有他们, 这是难) 。 尤其是, 你(们)可以(可能)找到具有" genksyms " 的一些问题, 其句法在核心的 2.0 和 2.1 版本之间改变了。
你(们)在 misc - progs 中找到的组件(模块)" 分配程序" 不同于我用章表示" Mmap 和 直接记忆体存取 " 在附近谈话的那个。 " 积极" 技术在现实世界中看起来有前途不, 所以我回到在" high_memory " 以后分配转动了记忆(存储器)。 看(见) misc - modules / 分配程序。 对(用 )于 细节的 README 。 -These are the source files for the book "Linux Device Drivers".
Here you find the complete sources that have been included in the
book. I have tested them as much as possible, but there might be some
problems left, especially with 2.1.43 (it s hard to test all of them
reliably when the underlying code base is continuously changing). In
particular, you might find some problems with "genksyms", whose syntax
changed between version 2.0 and 2.1 of the kernel.
The module "allocator" that you find in misc-progs is different from
the one I talk about in chapter "Mmap and DMA". The "aggressive"
technique didn t look promising in the real world, so I turned back to
allocating memory after "high_memory". See
misc-modules/allocator.README for details.

Description: UNIX提供了程序共享内存的机制，Linux内核从2.0开始也加入了这一功能。mmap(memory map)函数用于建立一段内存，使之能够被多个程序读写。它创建一个指向一段内存区域的指针并将其与特定的文件内容关联。-UNIX provides a mechanism for sharing memory, Linux kernel 2.0 from the beginning of this feature is also added. mmap (memory map) for the establishment of a section of memory function, so that multiple programs can be read and write. Point to a section of it to create a pointer memory area and the content of the document with specific relevance.

Description: 摘 要: video4 linux提供了一整套linux环境下操纵视频设备的函数接口,首先通过对video4 linux函数的调用成
功实现了两种方式(内存映射(mmap)和直接读取( read) )下摄像头数据的读取 然后对读取到内存缓冲区中的
RGB数据流进行分析,实现了同时对两种特定颜色(红、绿、蓝等)的识别,并给出相应色块的端点坐标 最后通过
对特定颜色箭头的端点分析,识别了箭头指向的角度 为了便于调试程序和验证结果,分析完成后把缓冲区中的
RGB流保存为BMP文件。-Abstract: video4 linux environment to provide a set of linux video equipment under the control of the function interface, the first function of the call video4 linux successfully in two ways (memory mapping (mmap) and direct reading (read)) under the camera data read then read into memory buffer of RGB data flow analysis, achieved at the same time for two specific colors (red, green, blue, etc.) to identify, and give the corresponding color coordinates of the endpoint final arrow on the specific color of the endpoint analysis, identification of the arrow point to the point of view In order to facilitate the debugging process and to verify the results of analysis after the completion of the RGB buffer to save it as a BMP file stream.
