Thanks, BillFM, for pointing out the obvious! You're right, latency on the bench should pretty much match latency at a reasonable distance and this idea of mine is actually silly. I got here by reading comments in the FPV flying world that go...

Thanks! What I mean by tether is that I temporarily run a jumper to the same digital pin on both Teensys (and ground of course). The button then connects ground to both pins at the same time, so they start same sketch on both Teenys...

In the setup I've described there is no way to signal back and I'm trying to keep things simple. How about this idea: Both Teensys run the same stopwatch sketch and I use a display on each to show elapsed time. Before making the measurement...

That all interesting, particularly the GPS idea, but I'm looking for something simpler. Perhaps I've not been clear? I want to start the two Teensys and then "pair" them so that they both have the same starting time. The Teensy with the LED...

I've done some searching and research on this, and I've come back confused. I want to measure the latency in a video broadcast system at various distances (for FPV drones). It's easy to do on the bench using one Teensy. An LED and a light...

Solved my own problem!

I've got the latest version of Ubuntu installed and running. I've got the Arduino IDE 2.3.2 installed and running. I've gotten as far as having all the Teensy stuff working except for the 00-teensy.rules bit. I don't seem to be able to...

Yes I have, but I'm trying to keep the package as small as possible. Just for fun, the solution I'm working on now just feeds both inputs (Bluetooth and Mics) to audio line-in. I get software control by using a couple of transistors as switches...

You are so right! I was setting up Ubuntu for the first time and just installed the IDE from it's software center, and it -- without my noticing -- it auto installed a version that was old as dirt! Problem solved by installing the latest IDE...

New install of Ubuntu. I've got the link in the Preferences/Additional Boards. I can connect to the Teensy (although IDE doesn't know what it is). When I go to the Boards Manager and try to install Teensy it starts and then says "Archive...

Thanks! I was hoping for something small and modular to just pop into the circuit. Such a critter may not exist :(

My project uses the Teensy 4.0 and an OLED display, powered by a lithium battery (5v). I want to add a low battery warning to flash on the display. This may be a truly stupid question (I'm learning as I go here), but can I feed the from the...

Forgive the length of this! My project includes Teensy 4.0, Audio Shield and a 5 watt amp. Sound is capture by a pair of TENS mics and provides a low cost hearing aid alternative using a bone-conduction headset. I've included functions to...

Thanks so much!

I've searched for an answer to this but I'm still confused: For the Adafruit Silicon MEMS Microphone Breakout that I'm playing with, the instructions say: "The output will have a DC bias of 0.67V so when its perfectly quiet that's what you'll...
