The-SCM-speed-measurement-procedures
一种基于AT89S52单片机的光电开关转速测量系统的设计。系统采用反射式光电开关产生与齿轮相对应的脉冲信号,使用AT89S52单片机采样脉冲信号并计算每分钟内脉冲信号的数目,即电机对应的转速值,最终系统通过数码管实时显示电机的转速值(A photoelectric switch based on AT89S52 Microcontroller speed measurement system design. The system uses a reflective photoelectric switch with the gear corresponding to the pulse signal, the microcontroller AT89S52 sampling pulse signal and calculate the number of pulse signals per minute, the motor speed value corresponding to the final system in real time by digital tube display the value of the motor speed)

实验箱中包括6位数码管,用扫描显示方法,其中段和位分别通过xxx4和xxx2来实现。xxx由译码地址决定。比如,cs接8000译码输出。用C语言实现:
1.首先实现定义一个数组,主程序中对其赋值(非压缩bcd码),由定时器中断程序实现6位扫描显示。
2.实现由储存BCD码的每一个字节的最高位表示小数点,并且将显示范围扩展到0——F,而非简单的BCD码。
3.用次高位和第5位表示闪烁和消隐,分别实现闪烁和消隐的功能。(shu ma guan experiment of 8051)

STM32_Si4730
本例程实现一个简单的AM FM收音机功能。本程序无显示,通过串口打印信息。程序固定预设了武汉地区的FM电台和AM电台列表。上电缺省是FM模式,通过按键可以切换AM和FM。(This routine implements a simple AM FM radio. The program no display, print information through the serial port. Program fixed preset FM radio stations in Wuhan and AM station list. On power-up default mode is FM, AM and through the key switch FM.)
