Hi there,
I'm trying to program LSM6DSV80x to read sensor values in -500Hz for a certain period of time and send them for process (thus no realtime process, but need timestamps). The sensor values include xl, hg_xl, gyro, and also Game rotation vector, gravity calculated by SFLP. According to the use case, all values will be read through FIFO. Mostly works well but I've come up with two questions.
- What timestamp means? Is it time of the latest FIFO entry, or of the next FIFO entry, or irrelevant with other entries?
- for game rotation vector, I got two consequtive entries having TAG=19 in FIFO everytime, at the same timing. Those two entries have completely different values. With the application note and the post in this forum, I understand the FIFO entry for game rotation vector hold only x, y, z elements and w needs to be calculated at the host side. For example (the order is, w - which I calculate, x, y, z):
LSM6DSV80X_SFLP_GAME_ROTATION_VECTOR_TAG game_rotation_mg: 0.81 0.00 -0.09 -0.32
LSM6DSV80X_SFLP_GAME_ROTATION_VECTOR_TAG game_rotation_mg: 0.24 0.00 0.31 0.89
How can I interpret these values?
Any comments are appreciated!
