K70 - MQX 4.1: Measure an input frequency

Question asked by arnogir on Feb 5, 2015

I'm working on a Kinetis k70 with MQX 4.1.1


I'm looking for a way to measure a Frequency of a square wave  signal on an Input (General IO or a specific IO if needed)


I see we can do something with LPTMR module, but I don't find the way to use it via MQX or with my own code but without interfering with MQX.


Have you some Idea, or exemple allowing to measure a Frequency on an input?
