    Well, hell, you are right. the file is just a stub in the Teensy3 fork of the AVR library. So there must be some issues with the Teensy 3 pin assignments or some such. I'll have to resort to the...

    The Teensy 5v tolerance is pretty good. You should not have a problem. Check the flowmeter to see if has pull up resistors. If not, you may need one on each of the SDA and SCL lines unless the...

    Brian,
    Given the availability of the Ublox GPS-RTK chips, I'm thinking of replacing my GPS subsystem connected to Teensy 3.2 and 3.5 devices. Do you think your library will hold up? I doubt you...

    Teensyduino compatibility

    I'm porting over some code from a Mega setup. And I'm guessing the naming conventions in Teensyduino for the Teensey chipset are different than the AVR units. I get a compiler error on the ISR line...
