Frequency measurement?

  • Hello!

    I'd like to measure fan frequency via the tach/sense pin. I'm also converting this signal level to be within the input range of the Omega2.

    My question is, is there hardware support for a GPIO counter? Measuring input frequencies is a pretty common activity with embedded controllers, where the Omega2 may be used. I'm surprised nothing turned up with a google search so wanted to ask here about how this might be done and any pointers you might have! (I'd also prefer not to have to add an additional ic to measure frequency.)
