This comprehensive book provides detailed materials for both novice and experienced programmers using all BeagleBone variants which host a powerful 32-bit, super-scalar TI Sitara ARM Cortex A8 processor. Authored by Steven F. Barrett and Jason Kridner, a seasoned ECE educator along with the founder of Beagleboard.org, respectively, the work may be used in a wide variety of projects from science fair projects to university courses and senior design projects to first prototypes of very complex systems. Beginners may access the power of the "Bone" through the user-friendly Bonescript examples. Seasoned users may take full advantage of the Bone's power using the underlying Linux-based operating system, a host of feature extension boards (Capes) and a wide variety of Linux community open source libraries. The book contains background theory on system operation coupled with many well-documented, illustrative examples. Examples for novice users are centered on motivational, fun robot projects while advanced projects follow the theme of assistive technology and image processing applications.

出现错误，首先要查找nginx的日志文件，目录为/var/log/nginx，在日志中发现了如下错误。
2013/01/17 13:33:47 [error] 15421#0: *16 upstream sent too big header while reading response header from upstream
查阅了一下资料，大意是nginx缓冲区有一个bug造成的,我们网站的页面消耗

利用STC8A8K64单片机,OLED 128X64显示屏和SD卡(用于存储图像bin文件)
简单说一下思路：通过SD卡移植文件系统，单片机驱动SD卡利用文件系统读取bin文件），之后就循环读取每一帧图像在OLED上显示。
