I am working on a project that uses a Teensy 3.6 logging accelerometers for impact testing of a vehicle and cyclist, with the accelerometers and Teensy mounted inside the head of the dummy cyclist. During the testing there have been issues with saving the data to the uSD card and I think it is due to the high energy impacts affecting the friction fit uSD. The uSD card remains in the slot, however the pins must loose contact or something because the data logging fails. During the previous testing we were only able to capture data in 1 of 4 tests, so the issue does not occur every time. Does anyone know if there is an acceleration limit for using the on-board friction fit uSD card slot? Or maybe it could be an issue with the Teensy itself? Thanks in advance!
