Hi all
Ive tried counting two pulses at once using interupts. if i count one pulse it works very well. at a second pulse there are both nothing close.. Ive tried both
with a teensy 3.5 and 3.6.
They seem to be interfering with each other.

I have also tried linking up three teensy's and having two count one different pulse and the third talk to the serial monitor.. But only print once the counting has stopped.

Has anyone been able to do this? or somthing like this? Im trying to build a two or three channel counter

TIA of any feedback
