Si4464-63-61-60

在51单片机上实现RS485通讯，能够实现与上位机的通信(RS485 mode on 51 single, able to communicate with the host computer)

单片机音频通信9170和9200，接收发送源程序(9170 and 9200 microcontroller audio communication, the receiver sends source)

rs422通信，此模块实现通信功能，使用Verilog语言(RS422 communication program, Verilog language, this module implements 422 communication function.)

51单片机C语言学习，C语言来编写单片机程序。Proteus仿真。(51 MCU C language learning, C language to write MCU program. Proteus simulation.)

C程序，红外遥控启停源码，可用于智能车，普通单片机遥控器即可(C programs, infrared remote start-stop source for intelligent vehicles, ordinary single-chip remote control to)

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)

说明：  超级好用！Arduino控制的麦克纳姆轮智能小车，可以蓝牙和手柄控制。(Super easy to use! Arduino-controlled McNam Wheel Intelligent Car can be controlled by Bluetooth and handle.)

说明：  NB-IOT智能燃气表用以实现燃气表的物联网功能(Nb-iot smart gas meter is used to realize the Internet of things function of gas meter)
