@Morten-Nissov Likely should all be off, it's been a while since I've had one of these come across my desk. I'll see if I can find one to reference.

@Alex-Kushleyev Sorry for the delay, didn't notice the alert. But great, thanks!

@Morten-Nissov ,

About the IMU dt, sorry, i got it backwards, the dt is 0.976ms, so that would be slightly above 1khz. So we are on the same page.

Yes, reducing the FIFO size results in more SPI read transactions, which means that the CPU / Kernel has to do more work. There is a per transaction overhead that is much more significant than just getting more data per single transaction.

Let's not bother with the PR because it is a 2-character change 🙂 . I will get to it and test it soon.

@Morten-Nissov I would advise trying to get some support from the PX4 community. I'm not aware of any use of i2c multiplexers in any current PX4 drivers but I think it's a useful feature. But that is the best place to get advice on PX4 development.

@Morten-Nissov , great! You are welcome. Make sure to change that 1us scheduling interval to a more reasonable value 🙂
