第十届蓝桥杯省赛代码
这是一个可以测量电压,频率的东西。
要求按下S4键的时候,数码管显示电压(显示小数,0.00~5.00),LED1亮,LED2灭,如果电压在一个范围,LED3亮否则灭。
再按一下S4,数码管显示频率,LED1灭,LED2亮,如果频率在一个范围,LED4亮否则灭,其中电压通过pcf8951检测,频率有NE555产生,并由跳线帽接到P3.4口,默认情况是LED开,数码管开,显示电压。
按下S5键的时候,DAC输出一个定值,再按一下,输出的电压和输入的一样,默认情况是输出的电压和输入的一样。
按下S6键的时候,关LED。
再按一下开。
按下S7键的时候,关数码管。
再按一下开。
