怎么使用计时器以RPM为单位测量速度

我用计时器和计数器测量电机转速。我没有得到合适的连接来计数传入的脉冲。
传感器安装在电机上,每转动一个脉冲。我想把它转换成RPM。所使用的传感器是附着在附件中的MOC 7811。请帮帮我!!

  I am using a timer and counter for measuring the speed of a motor in RPM. I am not getting the proper connections for counting the incoming pulses.
    The sensor is mounted on the motor which gives one pulse per rotation. I want to convert it in to RPM. The sensor used is MOC 7811 which is attached in the attachments. Please help me !!

在最后一次计算频率测量的问题数量时,你应该把答案汇编在一起,准备一个备注:

  @dana: counting the number of questions regarding frequency measurement in the last time, you should compile your answers together and prepare an appnote :)

我的基本观点是这样的。
并用各种方法覆盖计数器,可以进行测量。纳入
帐户定时,选择的方法的最大计数率。
最后一个做这件事的人很有启发性,Dave Van Ess在PSoC 1上。
我投的是柏树。
问候,Dana。

     以下为原文
  @hli, basic ap note like this should come out of Cypress in my humble opinion,
    and cover various ways with a counter one can do the measurements. Take into
    account timing, max count rates for method chosen.
     
    Last person to do it, was quite instructive, was Dave Van Ess on PSOC 1.
     
    My vote is Cypress do it.

我应该用更大的笑脸…
当然,这样的注释应该来自柏树,尤其是当问题被问到这样的奥芬时。但我刚才看到你总是为这个话题提供了很多有用的信息。也许我应该编译一个博客帖子,因为我已经有一个解释CPLD实现互惠计数器…

  @dana: I should use larger smileys...
    Surely such AppNotes should come from Cypress, especially when the question gets asked so otfen. But I just saw that you always provided so much useful information for this topic. Maybe I should compile a blog post out of this, since I already have one explaining the CPLD implementation of a reciprocal counter...
