    Hah! Thanks! Yes, I see you can't go over VDD+.3V in the datasheet. You also can't measure lower than +.256V as well.. interesting. I guess this is a good time for me to learn about clamping ...

    Hi Larry, that part actually looks pretty ideal - especially if that library works without issues with the teensy.

    If I'm using an external ADC then I guess I won't have access to all of the nice...
  3. ADC recommendation for 15-16bit DC voltage measurements + teensy support

    Can anyone recommend an ADC with at least 15 bits of resolution that would be decent at accurately measuring slowly changing DC voltages.. from 0-200Hz.

    Would be great if the ADC could measure up...

    Totally, I understand Paul. I'm not suggesting getting rid of any existing Library at this point, I'm just suggesting that in cases like this the extended functionality could have been incorporated...
  5. Oh perfect, thank you! I didn't even see...

    Oh perfect, thank you! I didn't even see FreqMeasureMulti listed on the main page. It's on the FreqMeasure page, but easy to pass by.

    Is FreqMeasureMulti rolled into teensyduino? Maybe just get...
  6. Measuring frequencies on two separate pins??

    Hey everyone,
    I'd like to use my Teensy 3.2 to measure the frequency of two separate audio signals. I see that the FreqMeasure and FreqCount library are hard-coded onto a single pin.. (the LED...
  7. help storing a large array of strings in the Teensy 2

    Hi everyone,
    I'm working on a little project that uses a Teensy 2 and display to scroll through a list of electrical component references and values. There is about 400 items in this list, and I...
  8. Teensy 3.0 - VREGIN max voltage / PWM output frequency?

    Hey guys,
    I want to power the Teensy 3.0 from an external source, and I'm just wondering what the maximum voltage that can go to VREGIN?

    I'm also wondering what the output frequency is on the...

    Thanks for this Paul,
    what was the problem with USB MIDI sendProgramChange in earlier versions?

    Thanks Paul, so does usb_names.h get edited directly or are there variables that I can change in the main program itself?

    How to change Teensy 3.0 PRODUCT_NAME ?

    Hey all,
    Is there an easy way to change the name that the teensy shows up as when plugged in? Instead of saying "USB Serial" or "Teensy Flight Sim Controls" I'd like it to say something else for my...
  12. Thanks Paul, this worked great!

    Thanks Paul, this worked great!
  13. Thanks for the reply Paul. That's a nice feature...

    Thanks for the reply Paul. That's a nice feature for sure!

    Unfortunately when I do that though, I only get 2.9V through AREF and not the 3.00V I was getting previously. The resistors that I'm...

    Thanks JBeale, I'm seeing about 12mA going through the Vref when the teensy is powered off.
  15. I just wanted to add some more details to this...

    I just wanted to add some more details to this problem. I'm using an LM431 shunt regulator to get my reference voltage (in this case 3.00V). When the teensy isn't powered up, my reference voltage...
  16. ARef input impedance? Other considerations?

    Hey all,
    I'm just wondering if the ARef should be driven directly by an external reference source, or if a resistor should be used? Also what is the impedance of this input, and does it change based...

    What to do with unconnected pins?

    Hi All,
    Just wondering.. once a project has been finalised, is there a best practice for what to do with the unconnected pins? Should they be left floating, or grounded, or something else?

    usbMIDI timing question

    Is it OK to fire off usbMIDI commands as fast at the teensy will allow it?

    I did a simple program reading a few inputs and sending the appropriate usbMIDI commands, but I noticed that sometimes...

    Thank you, I couldn't find information about the stability over temperature of the 3.3V regulator within the microcontroller. Looks like an external reference is the best way to go. No worries about...

    Thanks for the replies Jp3141 and Paul,

    Offset errors aren't a problem, the most important thing is that the scaling is accurate and linear. As for resolution, getting at least 10 bits of useful...

    Thanks for the reply, that's sort of what I was suspecting. I can divide down the 0-10V as you suggested, but with the 0-5V signal having scale accurately is very important. Would that mean I should...
  22. External Reference voltage maximum? (How to sample 0 - 10V)

    Hi everyone,
    I'm working on a project where I need to sample three different voltages. Two are 0-10 V and one is 0-5V. Before I release the magic smoke, I just wanted to ask here if there are any...
