说明：  编制MCS-51程序使步进电机按照规定的转速和方向进行旋转，并将已转动的步数显示在数码管上。 　　步进电机的转速分为两档，当按下S1开关时，加速旋转，速度从10转/分加速到60转/分。当松开开关时，减速旋转，速度恢复为10转/分。当按下S2开关时，按照逆时针旋转；当松开时，按照顺时针旋转。 　　本程序要求使用定时器中断来实现，不准使用程序延时的方式。(The MCS-51 program is programmed to rotate the stepper motor according to the specified speed and direction, and the number of steps that have been rotated is displayed on the digital tube. Stepper motor speed is divided into two gears. When the S1 switch is pressed, the speed is accelerated from 10 rpm to 60 rpm. When the switch is loosened, the speed will be reduced to 10 rpm. When pressing the S2 switch, rotate counterclockwise; when loosening, rotate clockwise. This procedure requires the use of timer interrupt to achieve, do not use the way of program delay.)

STM32F103单片机逆变器源码,大家知道， 市电或其他的交流电可以通过二极管或可控硅的单向导电性整流成直流电供 给需要使用直流电的场合。这种把交流电变换成直流电的过程我们叫做整流，也叫做顺变。 那么逆变呢？我们自然地就会想到，应该就是把直流电变换成交流电的过程。逆变电源就是 相对于整流器而言通过半导体功率开关器件的开通和关断把直流电变换成交流电的这么一 个装置。 逆变电源也叫做逆变器.(STM32F103 microcontroller inverter source, we all know, city power or other AC can be diode or SCR one-way conductivity rectifier into DC power supply For occasions requiring direct current. This process of converting alternating current into direct current is called rectification, which is also called commutation. What about inverting? We naturally think of the process of converting direct current into alternating current. Inverter power is As opposed to a rectifier, the direct current is converted into alternating current through the turn-on and turn off of the semiconductor power switching device Unit. An inverter is also called an inverter)
