Good Morning,
I would like to use a Teensy 3.2 or 3.6 to perform timings measurement of 3 digital signals.
Those signals are expected to be digital pulses with a frequency of 1.5Khz up to 6Khz, and I need to record the rising edges timing of those 3 signals during a few minutes.
Ideally, each time a rising edge is present on one of the 3 inputs, i would get an absolute time that would be sent over the serial port / USB.
As I understand, the FreqMeasure is not doing that exactly, as we get as information a time elapsed since last rising edge occurs. Is this correct?
If we accumulate those time elapsed over a 5 minutes period, are we going to accumulate a large error, or the elapsed timings returned by FreqMeasure Multi will be accurate down to a clock cycle?
I basically use the Teensy as a 3 way logic analyser over 5 minute...
Thanks for your help.
