通过STM32,实现指针式电子时钟编程的方案。(The Scheme of Implementing Pointer Electronic Clock by STM32)

说明：  注:protel电路图 1.INPUT12为高压气压和低压压传感器输入端. 2.OUTPUT为充气输出控制端. 3.当高低压有接地信号时,电机正转,气阀打开. 4.INPUT2低气压时有信号时,充气OUTPUT输出,充气电机转. 5.RS1与RS2是调节阀门距离用地 6.RS3是与气阀电机同步时,是气阀电机的转动圈数传感器. 7.RS4是调节延时时间用地(Note: protel circuit 1.INPUT12 and low-voltage high-pressure pneumatic pressure sensor input. 2.OUTPUT output control for the inflated side. 3. When the high and low pressure have a grounding signal when the motor is transferred, the valve opens. 4.INPUT2 low pressure when there is signal output OUTPUT inflatable, inflatable motor switch. 5.RS1 and RS2 is the regulator valve from the land 6.RS3 synchronous motor with the valve, the valve motor is rotating circle the number of sensors. 7.RS4 delay time to regulate land)

STM32F10X USB批量传输功能，并有上位机测试程序，上位机使用libusb + vc6.0(STM32F10X USB bulk transmission，and pc test program(use libusb and vc 6.0))

说明：  中国移动物联网NB-IOT模块m5310的pcb封装，现成的，直接用(China Mobile NB module m5310 pcb package)

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)

这是一个液晶的测试程序,是一款用ST7920做芯片的12864液晶的程序,绝对可用,方便而且可移植调用,还附有说明书(This is a test procedures for liquid crystal, is a ST7920 to do with the 12864 chip LCD procedures, absolutely available, convenient and portable call, accompanied by brochures)

CCS所有功能例程,实现AD采样、pwm产生等功能(CCS all functional routines, realize AD sampling, PWM generation and other functions)

说明：  使用msp430f5529产生pwm波的基本例程(Using msp430f5529 to generate PWM wave basic routine)

说明：  用于指导AD9361的器件说明，并指导如何通过AD9361搭建SDR平台。(It is used to guide the device description of AD9361 and how to build SDR platform through AD9361.)

说明：  单片机 LCD12864显示演示程序(Singlechip LCD12864 show demo)
