Before I move on too fast, How would I set the interrupt priority on pin 23 ? How would I check what the priority level is ? Thanks again.

Yes, the sensor was the problem. I did not realize the lm393 was so slow. I added an 74C902 to the output of the lm393: Much better ! Thanks all.

Yes, I did think of that. I am looking for an 74xx14 Schmitt-Trigger device to test that out.

I copy-n-pasted your code into Arduino 1.8.10 IDE. Works as described. The Hall Effect sensor is causing the problem (??).

Any idea about the >100uS interrupt latency ?

I am new to Teensy. I have a Hall Effect sensor: https://www.amazon.com/gp/product/B00W029QYC , with the DOUT pin connected to pin23 of the Teensy, Vcc is connectd to 3.3V on the Teensy. My Code: const byte Column_One_Pin = 23; const byte debugpin = 21; void setup() {...

Thank You !

Is there any example code on how to access hardware registers on the Teensy 3.6 ?
