步进电机的工作原理，可以详细了解步进电机的工作原理，对于时序问题，也是个很好的了解(Stepper motor works, you can learn more about the working principle of stepper motor, for the timing issue, but also a very good understanding of)

说明：  基于Tm4C123G的三相SPWM，能够实现DC_AC的变换 可结合现在流行的微电网和泛在电力物联网技术(Three-phase SPWM based on Tm4C123G can realize DC_AC transformation. It can be combined with the popular microgrid and ubiquitous power Internet of things technology.)

说明：  本课题对基于单片机的交通灯控制系统进行设计。以MCS-51系列单片机为控制核心，设计并制作交通灯控制系统，用于十字路口的车辆及行人的交通管理。东西南北四个路口具有左拐、右拐、直行及行人4种通行指示灯，并分别用计时器显示路口通行转换剩余时间，在特种车辆如119、120通过路口时，系统可自动转为特种车辆放行，其他车辆禁止通行状态。(Traffic light control system based on SCM (Single Chip Microcomputer) is designed in this paper. System requires that MCS-51 series SCM is used as CPU. Traffic light control system should be designed and made .There are four groups light which indicate to turn left, turn right, and go straight ahead and pedestrian access in east, west, north and south four directions. Timer shows traffic conversion remainder time. When special vehicles, such as 119,120 go through, the system can automatically allow special vehicles running and other vehicles is prohibited.)

内容：1、本程序用于测试4相步进电机常规驱动 2、需要用跳帽或者杜邦线把信号输出端和对应的步进电机信号输入端连接起来 3、速度不可以调节的过快，不然就没有力矩转动了 4、按s4（设置成独立按键模式）可以控制正反转 (Content: This program is used to test the four-phase stepper motor conventional drive 2, you need to jump the caps or the DuPont line signal output and the corresponding stepper motor signal input to connect, the speed can not be adjusted too fast. otherwise there is no torque rotation, set individual keys by s4 () can control the reversing)

定时器扫描矩阵键盘，让你彻底摆脱delay(Timer scan matrix keyboard, let you completely get rid of delay)

本程序是使用STM32开发蓝宇第四代线性CCD的例程，附有CCD与STM32的接线说明。程序是基于STM32F103ZE单片机的，可移植。(This procedure is the use of STM32 development Lan Yu fourth generation linear CCD routines, with CCD and STM32 wiring instructions. The program is based on the STM32F103ZE microcontroller, which is portable. )

Arduino 对接收到的信号进行解码操作，从而得到按键信息，根据按键值控制舵机。(By decoding the received signal, the key information is obtained and the steering gear is controlled according to the key value.)

数模转换芯片DA0832直通方式驱动一个发光二极管，由暗到亮循环( )

基于单片机的 环境光检测并通过1602液晶显示(Based on single chip environment light detection, and through the 1602 LCD display)

说明：  利用STM32控制两个舵机进而控制一个二维云台；直接输入角度就可以用(STM32 is used to control two steering gears and then a two-dimensional pan tilt table)
