    Counting the number of pulses per precise time interval on BeagleBone Black

    curr93

      Dear colleagues,

       

      I'm newcomer in BBB hardware "technology" and I'd like to know is it possible to implement on this device - counting the number of pulses (from any discrete input) for an predetermined time interval, for example 10...50 milliseconds ? 

      In other words I want to create simple frequency counter in the range of 10...90 KHz (rectangular pulses).

      Is it possible to estimate in advance how accurate the frequency measurement will be? And will there be enough resources of BeagleBone Black?
