cks32f103c8t6控制步进电机与舵机，步进电机是28byj48，舵机频率是50hz,本人小白，希望和大家一起学习(Cks32f103c8t6 controls stepper motor and steering gear. The stepper motor is 28byj48 and the steering gear frequency is 50hz.)

芯片：STC12C5A60S2 晶振：16MHz 波特率：4800bps 引脚定义：串行口1： 发送————TxD/P3.1； 接收————RxD/P3.0 串行口2： 发送————TxD2/P1.3；接收————RxD2/P1.2 功能描述：STC12双串口通信（中断方式） 当串行口1接收GPS数据后(4800波特率)，将此数据由串行口2发送出去 当串行口2接收数据后，将此数据由串行口1发送出去(Chip: STC12C5A60S2 Crystal: 16MHz Baud Rate: 4800bps Pin definitions: Serial port 1: Send TxD/P3.1 receiving RxD/P3.0 Serial port 2: Send TxD2/P1.3 receiving RxD2/P1.2 Function Description: STC12 Two serial communication (interrupt) When a serial port after receiving GPS data (4800 baud), this data is sent out by the serial port 2 When the serial port 2 receives data, this data is sent out by the serial port 1 )

说明：  用mcs-52系列单片机实现等精度频率测量，T1引脚接被测TTL信号，晶振22.1184MHz，对任何频率都可以实现很高精度的测量（精度<1 )，结果从串口字符串输出，波特率115200，可以用串口调试器观察结果.(With mcs-52 family of single chip and other precision frequency measurement, T1 pin then measured TTL signal, Crystal 22.1184MHz, any frequency can be achieved very high accuracy of measurement (precision<1 ), the result string from the serial output , baud rate 115200, serial debugger can observe the results.)
