    I would really like to have access to long file names and 44100 sample rates are what I use for all my Audio recording projects so that would be a nice capability as a standard feature. I have not played with the Teensy audio stuff in a while due in part to the confusion over how to get long...

    Teens 3.2 - Strange behavior on pin 14?

    I see a 1 on pin 13 (numbers start from 0) I expect it might be related to the LED on that pin

    teensy not so teensy?

    I find it's much better to have a supported product, especially S/W support than to have the latest bells and whistles or specific needs. It's great that you can find alternatives, and if you can make them work for you awesome. But for those of us not fully involved with the micro architecture...

    new custom midi controller

    There are few that work for PJRC, most of us are users who try to support each other. I like oddson's suggestion in #22. I hope you have success.

    Xbee and teensy 3.2 communication

    Wow I posted a response and must've hit the wrong button. Probably was TLDR :) but when I refreshed the forum my response was gone wo I will reply again but briefer as I am out of time. Check into AT mode for the XBee, it makes the point to point comm transparent. You'll need some sort of...

    Xbee and teensy 3.2 communication

    So the Quick answer to number one is yes, the question is what do you do with the received data at the XCTU terminal? but if you have the XBEES set up direct link mode whatever is sent to one would be repeated at the other. That is the simplist mode of using the XBee (I have only worked with...

    new custom midi controller

    I'm jumping into this late, but it appears from reading the thread from top to bottom and looking at your video that you have built a midi controller using a teensy and can successfully send midi control messages to the software. The first problem I observe related to your current concern is...

    Using SparkFun microSD card adaptor with Teensy 3.2

    Another option might be the device pulls more current than the T3 can supply at 3.3v I could not find any reference to the current requirements at 3.3 or 5.v, but hooking up to 5v as described above would bypass the 3.3v T3 regulator. The T3 3.2 is spec'd to supply 250 mA max.

    It would be real nice to have a legend for the ports, I know there's not much room but if only on the back and only for the 3 serial port types (as the others are pretty obvious) it might help newcomers.

    Teensy 3.1 / adafruit 1.77" tft

    I can't really comment on the specific example you are asking about since you did not include the whole program or a link (see Forum Rule) perhaps it is an example with no read need? SPI on Teensy LC and T3 works with pins identified on the cards there are library calls to set both MOSI/MISO...

    Is debounce no longer a valid OneWireKeypad member?

    O.k. to answer your original question, debounce is no longer an option, the library has it commented out. I do not see any reference on how it would have been used. it looks like adjusting NUM_OF_SAMPLES in the library is how you adjust the code for sensitivity and limiting false returns. //...

I did a little looking and I can't find the OnewireKeypad.h in the standard Arduino 1.6.9 install nor in the T3 Install.

    Teensy 3.2 with Audio Board and ILI9341 2.8 inch Touch Screen

    Well if you're not needing the extra speed from the high performance graphics lib you can certainly make the touch and sound work. in My example I default to using the Ada fruit graphics lib with the audio card and it works reliably, but you lose the fonts and accelerations. I'll look into...

    Translating Lidar Lite I2C example to Teensy
