jfs 源码，大家都熟悉不用多说了吧，自己动手移植吧--JFS source code.

一个简单的嵌入式程序-a simple procedure Embedded

资源描述ENC28J60在STM32下的驱动代码，移植可用。希望有帮助

FLASH文件系统的源码，Flash memory is a nonvolatile memory, which allows the user to electrically program (write) and erase information. The exponential growth of flash memory has made this technology an indispensable part of hundreds of millions of electronic devices. Flash memory has several significant differences with volatile (RAM) memory and hard drive technologies which requires unique software drivers and file systems. This paper provides an overview of file systems for flash memory and focuses on the unique software requirements of flash memory devices. -FLASH file system source code, Flash memory is a nonvolatile memory, which allows the user to electrically program (write) and erase information.

用em4094和STC12C5412合成二代证读写器，该文中有完全原理图和软件设计思路 -Synthesis of second generation with the em4094 and STC12C5412 card reader, the text has full schematics and software design ideas

&我的项目是RFID门锁系统。这个系统是用来打开门与RFID传感器。什么时候你要开门，就必须把射频识别卡放到门上接受者ARM控制器读取卡中的数据，检查卡中的代码，比较eeprom中的用户代码和卡中的代码是否正确是的，门会为这个人打开的。

在数字电路的设计中，时序设计是一个系统性能的主要标志，在高层次设计方法中，对时序控制的抽象度也相应提高，因此在设计中较难把握，但在理解RTL电路时序模型的基础上，采用合理的设计方法在设计复杂数字系统是行之有效的，通过许多设计实例证明采用这种方式可以使电路的后仿真通过率大大提高，并且系统的工作频率可以达到一个较高水平-In digital circuit design, timing design is a main indicator of system performance in high-level design methods, control of timing was also a corresponding increase in the abstract, so more difficult to grasp in the design, but in understanding the RTL circuit timing model based on rational design methods used in the design of complex digital systems is a well-established through many design examples prove that this approach can make the circuit after the simulation significantly improve pass rates, and the system operating frequency can reach a high level

symbian下mp3文件的解码源代码，附有小例子-symbian documents under mp3 decoder source code, with small examples

ADC的分辨率是指使输出数字量变化一个相邻数码所需输入模拟电压的变化量。常用二进制的位数表示。例如12位ADC的分辨率就是12位，或者说分辨率为满刻度FS的1/ 。一个10V满刻度的12位ADC能分辨输入电压变化最小值是10V×1/ =2.4mV。 -ADC的分辨率是指使输出数字量变化一个相邻数码所需输入模拟电压的变化量。常用二进制的位数表示。例如12位ADC的分辨率就是12位，或者说分辨率为满刻度FS的1/ 。一个10V满刻度的12位ADC能分辨输入电压变化最小值是10V×1/ =2.4mV。
