    Read the licenses of the code that you use from external sources (i.e. the Teensy cores) and follow the guidelines in those. If license obligations are too onerous, don't use that library and write your own code instead.

    Thanks for posting! I'm going to have to think through this a bit more.

    I'd be super keen if someone got NAND flash working with Teensy. Having storage size rivaling an SD card in a soldered on solution would be awesome.

    Not with the Teensy 4.0, since the bootloader chip isn't available yet, but plenty of people have with the Teensy 3.x. Be sure to read through the links on this page: https://www.pjrc.com/store/ic_mkl02.html With...

    Maybe I'm misunderstanding your goal, but I would think about this some more. Are you actually trying to get analog data or digital pin state (i.e. on or off)? If it's digital pin state, then you could treat each pin as...

    Great to hear! Yeah, with the platforms I've been testing for, they're always moving some.

    Yes, they're no longer for sale - will need to be updated to work with the Teensy 4 / 4.1 pinout.

    Here is the Backpack pinout. I'd be curious to know if/what would need to be changed to work with Teensy 4.0. Please let me know if you need additional information. There were two voltage regulators available, the...

    Yeah, seems weird - it's too big of an error to be declination. I haven't had a chance yet to do a deep dive into what's going on.

    Attached is a zip of the corrected code. It was being used with some CMake build tools, but should be easy enough to get it working as an Arduino library. Requires Eigen. Yaw tracking has been good while moving. Here...

    Love the F9P's - especially adding in CORS corrections, fast time to fix and low standard deviation. Haven't done too much with this filter, there were a couple minor errors discovered, but mostly once it is tuned -...
