    Gen 2 UHF RFID Reader

    I'm looking for a Gen 2 UHF RFID reader to integrate into a Teensy project. Does anybody have one they've used successfully? I have failed so far with the SparkFun, my shame is documented in this...

    I don't have a scope myself, but might be able to get access to one. What would I look for? Wires are good according to my meter and the same wires work with the Arduino UNO when testing over...
  3. When I try running the USBtoSerial example I get...

    When I try running the USBtoSerial example I get the single character 'C' in the Serial Monitor, when the reader is first powered on. I don't know if that is a proper interpretation of the firmware...

    I tried swapping the wires, to no avail.

    This is the response I got from SparkFun:

    "The switch just selects which pair of shield pins the module is connected to. HW-UART connects the module...

    Awesome, thanks for taking another look. I think the setupNano function places them in that order. When you say a library issue, you mean the library for the reader itself?

    EDIT: Just tried...

    Incorrect. Maybe you saw a bunch of references to Serial and stopped reading? Check lines 101, 105, 106, 109, 125 and 129. I probably should have pointed them out.
  7. Simultaneous RFID Reader Serial Communication to Teensy 3.2

    I'm using the SparkFun Simultaneous RFID Reader and would like to communicate over hardware serial with a Teensy 3.2. I successfully tested the reader as a shield with an UNO, using an example...

    Great advice BJB. I think your point about empirical data is the one that stands out. We will do as much real world testing as we can in the SoCal sun, get some heat lamps, ship one to the client...

    Thanks tonton,

    I'm actually asking what the thermal and humidity limits of the Teensy itself are. What is the maximum temperature and humidity we can expose it to and still get reliable...

    Temperature and Humidity (again)

    Sorry, I've read over a dozen threads on this - but I didn't actually see many answers in them...

    Are the environmental operating conditions for the Teensy 3.2 or LC known? We want to use them...

    ooh, I like that idea. I'll give it a shot - hopefully they don't get knocked out of position easily without power, that might be perfect.
  12. I don't believe so - I think those continuous...

    I don't believe so - I think those continuous rotation servos don't actually allow control over the angle of rotation. The control pin is for speed and direction if I understand correctly:

  13. Tiny, low power drive for teensy watch/compass

    I'm drawing up a Teensy compass with a fake needle, powered by battery. I am trying to get a full day out of it and the mechanism to move the needle is obviously the biggest power draw. I think I...
  14. Got it. Thanks again, this is great.

    Got it. Thanks again, this is great.

    Done, thanks Paul!

    And thank you Michael, for catching those mistakes. The display pins were meant to be a straight copy from this page, but I messed them up. I believe the T_* pins are for...
  16. Bunch of devices to connect - check my work?

    I am trying to work out a setup with SD Card, RFID reader, WiFi, Ultimate Sensor Fusion, amplified audio out, and a display.

    This is what I came up with to connect it all, I'm hoping someone can...

    Finding I2S Pins on Pinout Diagram

    I'm having trouble understanding which pins on a Teensy (or any other micro) are suitable for I2S. On the "Output to I2S" page I see the following:

    Pin 09 = BCLK
    Pin 11 = MCLK
    Pin 22 = TX
    Pin...
