AT89C2051驱动步进电机的电路和源码(用keilC51)(AT89C2051 stepper motor drive circuits and source code (using keilC51))

ST低功耗MCR stm8l15x 标准固件库，对初学者入门很有帮助(ST' s low-power MCR stm8l15x standard firmware library entry helpful for beginners)

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)

关于使用saber软件的逆变器仿真，可以更精确的达到仿真结果。(saber inverter)

串口发射1khz信号或者并口发射1khz信号，(Transmitting 1 kHz signal)

在单片机上使用的超声波测距程序，使用keil变异，使用lcd1768(Embedded in keil project uses ultrasonic distance measurement using lpc1768)

按键控制8×8LED点阵屏显示图形,proteus仿真(Button control 8 × 8LED dot matrix screen display graphics)

直流电机开环调速系统仿真模型，且参数完整(DC open loop speed control system simulation model and parameters complete)

多层pcb板，可以直接制版并输出。本板是六层pcb，由dsp+arm共同组成！(Multilayer pcb boards, and can output to plate. The board is six pcb, composed of the dsp+ arm!)
