stm32芯片--用GPIO口模拟I2C驱动MPU6050陀螺仪(Stm32 chip- using GPIO port simulation I2C driver MPU6050 gyroscope)

CC2530 步进电机控制实验。一个简单的例程(CC2530 stepping motor control experiment)

手持振动仪，自动通过傅里叶变换，提取峰峰值，来自动调整震动的幅度，(Handheld vibration, automatic Fourier transform, peak extraction, to automatically adjust the amplitude of vibration,)

本设计主要实现用按键控制步进电机四相单拍、四相双拍和四相八拍三种方式切换， 正、反转及其加、减速，并能在LCD上显示其运行状态（速度和转向）。(The design of the main keys to achieve control of stepper motor with a single shot four-phase, four-phase two-and four-phase eight-shot shoot three ways to switch Positive, reverse its acceleration, deceleration, and in its operational status on the LCD display (speed and steering).)

学4年来做过的竞赛以及老师的科研项目所积累下来的c51源代码，一共有40(4 years of study done as well as the Teacher of the competition accumulated research c51 source code, a total of 40)

DAC5615的使用，能够控制输出电压为设定电压，并保持恒定。(DAC5615 used to control the output voltage setting voltage, and constant.)

一个数字类型可提高开关电源的设计与实现，可以是很好的借鉴，但是要用特殊软件打开，把文件后缀复制到百度就可以找到(A digital type can increase the switching power supply design and implementation, can be a good reference, but use special software to open, copy the file suffix can be found on Baidu)

在定时器控制下反复的裁减一幅图像和改变其大小(timer under the control of the repeated cuts an image and change its size)

本程序实现基于单片机的自动电阻测试，包括AD芯片的使用和继电器的控制。(This procedure to achieve automatic resistance measurement based on single chip microcomputer, control and relay includes a AD chip.)
