YAFFS updates YAFFS2 good support NANDFlash file system

一篇描述对2812通过can在线升级方法文章。对设计过程中的难点进行了讲述。包括文件的转换，引导模式，以及其他一些注意事项。

电子密码锁设计，设有详细的电路图和C语言代码；用KEIL编译生成HEX文件，可用PROTUES方针-Electronic code lock design, with detailed circuit diagrams and C language code with KEIL compiler generated HEX file that can be used PROTUES approach

这是嵌入式linux的busybox源代码，它主要是针对motorola公司的32位芯片powerpc上的，当然也可以移植到其他的芯片上-This is the source code of busybox under embedded linux, it is mainly designed for 32 bit processor PowerPC of Motorola Company, and it can be removed to other processors of cource.

一个用于PC直接写端口及内存的程序，少加修改就可用于pci卡的驱动，完整的工程代码，非常不错-a written directly for the PC port and the memory process, less modification can be used to drive pci cards, and complete code works very well

应用背景STM32F103ZET6百为开发板的贪吃蛇源代码，主函数基本每一句都有注释，按照自己的思路写的，能够直接在百为STM32F103的板子上运行，代码不长，个人觉得比较清晰。关键技术主要应用了链表数据结构和利用单片机自带的AD采样来产生随机数。贪吃蛇的每一节身体都是链表中的一个元素，而食物出现的位置通过AD采样的末位组合产生的随机数来确定。

关于嵌入式arm开发的几个头文件描述，需要多用心阅读。-Embedded arm on the development of several header files to describe the need to more carefully read.

keil和Proteus联调所必须的一个文件，看到好多网友都在找，所以传上来，希望对大家有用-keil and Proteus FBI needed a file, see a lot of users are looking for, so Chuan-up, in the hope that useful to everybody

本文介绍了如何用AD识别用户输入的键盘的方法，较之点阵识别有其不可替代的优势；因为如果用4*4的话须消耗8个I/O口，而如果系统有AD功能的话就可能轻松解决了。 单片机8051F330发给ARM然后发给电脑。 其原理就是利用电阻的分压，按键时产生不同的电压，再用中断快速读取电压；然后对其进行编码，通过串口软件EASYARM在个人电脑里显示；经实验观察，效果还可以。 -This article describes how to use AD to identify the user s keyboard input methods, compared with dot-matrix recognition has its irreplaceable advantages because if we use 4* 4, then to be consumed eight I/O port, and if the system function in AD, then on may be easily resolved. Singlechip 8051F330 distributed computer and then distributed to ARM. Its principle is to use the sub-ballast resistor, when keys have different voltage, and then quickly read voltage interruption then encode, through the serial port software EASYARM in the personal computer display by experimental observation, the effect can also be.
