    Teensy 3.1 and USB connect / disconnect

    I think this is "just the way it works". I've trained myself to always disconnect TeraTerm before powering down or unplugging the Teensy. Greg

    Progress on a new exFAT SD library.

    Bill, Any progress on the ExFat library? I have a project that needs to talk to an ExSd card created by a dashcam. Greg

    Low Power "Green" Battery Operation Solutions For The Teensy 3.

    I'll do that and let everyone know how it goes. I'm just running the stock example with no changes.

    Low Power "Green" Battery Operation Solutions For The Teensy 3.

    Back in April in this thread, Massel reported that he was having trouble with the GPIO_WAKE part of the DeepSleep_Simple example for the LowPower_Teensy library. I'm running into this same problem. LPTMR_WAKE works as expected, but GPIO_WAKE behaves as if it never goes to sleep. I can tell it...

    Teensy 3.1 and USB connect / disconnect

    I have a simple program that loops on writing a string to the USB serial port. I apply external battery power to the Teensy a) Now plug in the USB cable: windows installs the com-port as seen in the device manager b) run TeraTerm and connect to the newly installed com-port. All is well --...

    Teensy 3.1 Reset

    Paul, Thanks for the explanation and history lesson. I'm sure none of these decisions are easy, especially with the desire to support new features yet remain backward compatible. What do you suggest for those who wish the functionality of a reset input? Is yanking the power an acceptable...

    Teensy 3.1 Reset

    Digikey P/N FDN337NCT-ND It passes the battery voltage from the input to the output when the gate is floating. If you connect the gate to the +V on the battery, it will turn off the output. I have it up and running right now on a different board And the switch I was going to use : SW1020CT-ND

    Teensy 3.1 Reset

    I was surprised when I figured this out as well. At first I thought the button on the board might act like a reset. Nope. Then I found this thread, and the schematics and board layout. There's no good way to expose the reset pin. Would have been better if the test point were on the top of...

    Teensy and Arduino and Iridium SBD

    Sorry to respond to my own post, but I added this to IridiumSBD.h void console(size_t m); and this to IridiumSBD.cpp void IridiumSBD::console(size_t m) { if (this->pConsoleStream) pConsoleStream->print(m); } Not sure why this was needed (or even if it will...

    Teensy and Arduino and Iridium SBD

    I've got a Sparkfun Pro-Micro up and running with the TinyGPS and IridiumSBD_Master libraries. I want to port everything over to the Teensy 3.1 to get more processor power and code space. TinyGPS works fine, but when I add in the Iridium library, I get compile errors. For example...
