51单片机电子钟

基于STM32开发板，通过模拟寄存器，验证I2C通信功能，(I2C_TwoBoards_ComPolling I2C Two Boards Communication Polling Example)

用P2P技术设计的一个简易聊天程序，要求不使用专用的主服务器，只要将好友添加到好友列表中就能检测好友是否在线，并相互发送聊天信息-Using P2P technology, design a simple chat program, asked not to use a dedicated master server, as long as the friend added to the Friends list will be able to detect friends are online, and send a chat message with each other

通过是与有限差分法，使用matalb模拟二维光子晶体(simulation of EM wave in two-dimensional photonic crystals using fdtd)

Equal area azimuthal projection

nRF24LE1基础实验代码，包括io口，流水灯，按键检测，蜂鸣器，随机数，看门狗，定时器，串口数据收发，串口控制led，adc检测，外部中断，flash读写，低功耗管理，休眠管理，OLED 屏幕，pwm输出等试验，十分具有参考价值。很不错的代码

dsp控制，单极性SPWM调制程序，希望对大家有用。(dsp control, unipolar SPWM modulation program, we hope to be useful.)

XP风格BUTTON，从别的地方转载，不错。-XP style BUTTON, reprinted from other places, yes.

计算光子晶体能带结构图的MATLAB源码文件，使用的方法为平面波展开。各物理参数均有注释，光子晶体结构可任意调整。(Calculation of photonic band structure of the MATLAB source code files, the methods used for the plane wave expansion. The physical parameters have comments, photonic crystal structure can be adjusted.)

说明：  线性链表的定义，遍历，查找，删除，排序。(Linear list definition, traversal, search, delete, sort.)

给MT4系统EA编程的入门级详细源码解说，力求让更多的MT4爱好者通过这个源码走进EA的时间。(EA for MT4 system programming code entry level detailed explanation, to allow more fans through this source into the MT4 EA time.)
