用于制作记事本

使用MD5算法对数据和文件进行加密，信息安全(Using the MD5 algorithm to encrypt the data and documents, information security)

说明：  STM32F429 FreeRTOS移植源码(STM32F429 FreeRTOS transplant source code)

RoundDisk幸运大转盘 旋转，精选ios编程学习源码，很好的参考资料。(RoundDisk lucky big turntable rotation, selection of learning IOS programming source code, a good reference.)

说明：  平台基于visual studio 2015，使用opencv实现霍夫变换检测直线(Implementing Hough Transform)

PIC单片机红外遥控控制继电器吸合或释放(PIC microcontroller infrared remote control relay or release)

说明：  数值分析中指数拟合和C语言程序实现，可以输出最终的函数表达式也可以对数据进行预测。(In numerical analysis, exponential fitting and C language program implementation can output the final function expression and can also predict the data.)

该程序实现了CC2530+SIM900a实现的gprs网关。能够收发gprs数据，收发短信(The program implements CC2530+ SIM900a achieve gprs gateway. Can send and receive gprs data, send and receive SMS The program implements CC2530+ SIM900a achieve gprs gateway. Can send and receive gprs data, send and receive text messages)

串口与pc机通讯，51单片机例程，只需要修改io口即可实现。(Serial communication with pc, 51 MCU routine, you only need to modify the io port can be realized.)
