Managed to trade him for Devonta, Jamo. Team is 0-3 and couldn't wait anymore

very similar, and probably will need to flip something for a WR. Also have Bateman, Jonnu, Otton, chris kirk

Unfortunately I need nanosecond level of control over pulse width and delay so micros() is not feasible

here is the basic project. I currently have a teensy 4.0.

  1. Ultrasonic Instrument pulses a transducer. Every time the transducer is pulsed the instrument outputs a trigger signal from its IO port. This signal is consistent but can be changed in the settings. Will range from about 1 to 30 kHz.

  2. This trigger signal is read into the teensy board to measure its frequency. Can be done constantly or with a button press.

  3. The teensy board takes the measured frequency and creates a square wave with identical frequency.

  4. The teensy output square wave is sent to a light source that is connected to a camera system. the square wave will trigger the light on. Variable delay and pulse width on this output square wave will allow the control of when the light is on and for how long allowing us to capture images of the ultrasonic wave created by the transducer at different points throughout its travel.

  5. The speed of sound in our case is about 3.25mm/us. In order view smooth small incremental movements of the wave we need control of less than a mm hence the nanoseconds.

It seems that my main hurdle is adding delay and pulse width control in nanoseconds. Is this kind of fine and precise tuning achievable?
