8路输入模拟信号数值显示巡检数字电压表可以测量0--5V的8路输入 模拟信号电压值,并在4位LED数码管上轮流显示或单路选择显示。
按系统功能实现要求,决定控制系统采用AT89C52单片机,A/D转换采用ADC0809。系统除能确保实现要求的功能外,还可以方便地进行8路其他A/D转换量的测量、远程测量结果传送等扩展功能。
采集 8 个通道的模拟量在数码管显示出来。模拟量值的测量范围是0-255,第2个数码管用于显示哪一个通道,后2个数码管用于显示采集的模拟量的值,每秒钟显示切换一下通道

定时器输出PWM波测试工程实例
(1)通过对PWM占空比的调节,实现小灯的渐亮的功能,当占空比为100%时再从0%逐渐增加.PWM的周期一定要足够的快,否则其输出电压的波动范围很大,且测不出一个稳定的电压值,这样通过就观察不到小灯渐亮效果. 另外,在改变PWM的周期和占空比之前和之后要分别禁止和使用TPM1,否则改变不起作用.-The timer output PWM wave test works (1) small lights fade function, when the dut
