这是philips公司mifare卡的读写源程序DEMO，在他们公司下载需要特殊认证，对于开发射频卡十分有意义-This is the philips company mifare cards read and write source DEMO, download in their company in need of special certification, for the development of the RF card is very meaningful,

简易的波形发生器源代码,基于NXP LPC2368-Simple waveform generator source code, based on the NXP LPC2368

基于AT89C51使用ADC0832进行模数转换和显示。使用proteus+keil，有仿真原理图和C程序。-Based on AT89C51 using the ADC0832 analog to digital conversion and display. Use proteus+ keil, a simulation schematic diagram and C programs.

里面主要是关于stm32的一些基础应用，能简单的学会使用stm32，有一些程序应用实例，基本包括了stm32设计过程中需要用到的

ARM cortex-M3系列处理器的代码，包括通用输入输出GPIO、模数比较器ADC、模拟比较器COMP。（IAR环境工程）-ARM cortex-M3 family of processors code, including general-purpose input-output GPIO, modulus comparator ADC, analog comparator COMP. (IAR Environmental Engineering)

该文件包括飞思卡尔生产的MC9S12XS128 的基本实验程序，对于学习单片机的新手来说，具有一定的参考价值，该程序包含了I/O,AD,PWM,ECT,PIT,SPI,SCI,CAN,IIC等基本模块，是一个很好的资料。

这是我从朋友那搞到的pic学习资料，很简单的啦-This is what I got from a friend that the pic learning materials, a very simple啦

优化级别必需为s,其他优化级别也不会导致编译时出错，但会导致运行时出错。原因涉及局部变量分配堆栈处理方式不同，也就是OS_CPU_A.c那个文件中的移植部分。还有就是其他优化涉及的中断自动保存寄存器的数量有所出入。-Necessary to optimize the level of s, other optimization levels will not lead to compile-time error, but it will result in run-time error. Reasons relating to the allocation of local variables, stack processing in different ways, that is, OS_CPU_A.c that the transplanted parts of the file. There are other optimization related to the interruption of the number of registers saved automatically have access to.

基于ARM内核微处理器操作系统的移植-based on the ARM microprocessor core operating system transplant
