是关于集成运算放大器应用电路集,我找了很久的东西,里面非常的全面,特地拿出来共享,我想对硬件工程师来说没有人会不喜欢这个东东吧~用超星打开-on Integrated Operational Amplifiers circuit sets, I find things for a long time, there is very comprehensive, specifically up sharing, I would like to hardware engineers who would not like it to the Eastern opened with Superstar

YAFFS Direct：脱离Linux、Wince等操作系统的Yaffs，没有那些系统接口，比较直接，可用于没有操作系统的情况，也可用于UCOS、FreeRTOS等小型系统。-YAFFS Direct，can be used with or without rtos. Simplified code, be easy use. It s great!!!

一个完整DVDROM代码(使用日立PICKUP)-a complete code (using Hitachi PICKUP monitor)

这个是比较详尽的飞利浦lpc22xx系列的资料，相对于lpc其他较少的资料而言，这个pdf还是比较全面的！-This is more detailed information on Philips lpc22xx series, as opposed to other less lpc information, this pdf is quite comprehensive!

用c++ 类累起来的简单菜单，对于做嵌入式开发的，gui来说，有一定参考价值。-use accrued up a simple menu, so for embedded development, gui, a certain reference value.

quartusII 中文使用手册，给广大cpld 及 fpga 开发用户使用，谢谢大家的支持。-Chinese quartusII user manual to the general development of CPLD and FPGA users, I would like to thank everyone

单片机仿真万用表源码及proteus电路图，详细的源码和仿真文件，完美运行，真正意义上的仿真，比较接近实际的万用表电路，而非简单的调试一个程序
