stm32f103测正弦波、方波的波形频率。(Measurement of waveform frequency by STM32F103.)

单片机c程序集(伟福）,环境为LAB6000，包含所有实验的程序，并附有详细的注释，难得的好资料，网上很难找。(Singlechip c assembly (Fu Wei), the environment LAB6000, contains all the experimental procedure, together with detailed notes, rare good information hard to find online.)

这是一个基于STC单片机，采用分离原件的125K的ID读卡器全套设计资料，其中包括原理图、PCB以及单片机源程序，还有我做设计时的参考资料。内容很全面的，以及在实物上验证过，可以正常运行。主要使用的天线为820uH。(This is based on STC microcontroller, the separation of the original 125K ID card reader full design information, including schematics, PCB and microcontroller source code, as well as I do the design reference. Content is very comprehensive, and verified on the kind, can operate normally. The main antenna is 820uH.)

此资料为AT45DB161D 的驱动程序，希望对使用此芯片的朋友有所帮助(This is a AT45DB161D driver, want to use this time to develop the chip would be helpful friend)

数据采集程序，采集波形图数据，并实现数据的存取(data acquisition)

刚才上传的频率计程序可能不太好，现在这个计数外部脉冲的程序，还是较好的，只是得自己从中截取出来(Just upload the program may not be a good frequency counter, and now this external pulse count procedures, or better, just get yourself out from the interception of)

EDAC driver for IBM CPC925 Bridge and Memory Controller.

esp8266测试源码,测试STA和AP功能。并且对TCP,UDP测试（来自原子）。(Esp8266 test source code, testing STA and AP functions. And for TCP, UDP tests ( atoms).)

Proteus7.12完美破解版.rar电路仿真软件很好用可以仿真单片数字模拟电路(Crack version Proteus7.12 perfect. Rar circuit simulation software can be very good with single-chip digital simulation of analog circuits)

STM32F405RGT6 的CAN1和CAN2相互通信，一个发送，一个接收，采用HAL固件库(STM32F405RGT6 of CAN1 and CAN2 communicate with each other, a sending a receiving using HAL firmware library)
