    Yeah, I would use SPI to communicate with that IMU. I typically use a large circular buffer to buffer the data and then write it to SD in 512 byte chunks. I tend to use the IMU data ready interrupt to trigger data...

    Hi you may want to check out my uBlox lib: https://github.com/bolderflight/ublox It's lighter weight than SparkFun; although, you do need to config the receiver yourself on u-center.

    Having no SD seems to make this project a non-starter. Assuming that you compress your IMU data to 2 bytes per channel (i.e. 16 bits to store each axis of accel data instead of a 32 bit float) and 2 bytes for each...

    Hello, in case you're unaware, I have an SBUS library that has been tested against Teensy 3.x, 4.x, and LC: https://github.com/bolderflight/sbus

    Thanks Mike! Didn't notice that there was a local array that was so large. Seems like in summary, the PROGMEM was working, we just had a local array overrunning the available memory. The float version I made also got...

    I tried aligning the array with the following and no improvement. Mike, I need to think about it some, but your solution using floats is probably the best - I think EGM96 doesn't need doubles. ...

    Correct, initialized and not expected to change; just a massive array. DMAMEM overflowed. I'm getting a "no match for call to '(CrashReportClass)". I'll have to look more into how using CrashReport works.

    Hi all - I'm seeing if I can implement an EGM96 geoid model on Teensy 4.x. Specifically, I'm implementing this library: https://github.com/emericg/EGM96 I renamed the EGM96.c file to a .cpp file and moved the...
