AT91的库函数结构说明PDF文档，好东西。

基于ARM7的开发板的存储器重映射驱动程序，文件里有程序的详细注释，对与在此基础之上的二次开发非常方便-based on the ARM7 development board memory re-mapping driver, the documents detailed procedures Notes right and the basis of this second development is very convenient

资源描述Key.c和Key.h  源文件实现了按键长按、短按、长按累加的识别，采用状态机制来实现按键消斗和不同按键状态识别，最大限度提升程序的运行效率和MCU利用率，该代码移植性，支持IO驱动按键，AD采样方式识别按键。采用DMA的方式获取AD采样数据，MCU采用STM32.

ARM cortex-M3系列处理器的代码，包括正交编码器接口QEI、中断控制Interrupt、硬件类型定义hw_types。（IAR环境工程）-ARM cortex-M3 family of processors code, including quadrature encoder interface, QEI, interrupt control Interrupt, the hardware type definition hw_types. (IAR Environmental Engineering)

FM25L256B是采用先进的铁电技术制造的256Kb非易失性存储器。铁电随机存储器（FRAM）具有非易失性，并且可以象RAM一样快速读写。数据在掉电后可以保存10年，同时消除由EEPROM和其他非易失性存储器导致的复杂性，开销和系统级别可靠性问题。 -FM25L256B is the use of advanced technology manufacturing ferroelectric 256Kb nonvolatile memory. Ferroelectric random access memory (FRAM) with a non-volatile, and can read and write as quickly as RAM. Data can be saved in the power-down after 10 years, while eliminating by EEPROM and other nonvolatile memory led to the complexity, overhead and system level reliability problems.
