Figuring out how ODR works on LSM6DSV16X (or any other ST IMU)

LionRelaxe

Hello group,

I'm a humble hardware guy integrating the LSM6DSV16X into a robotic application.

We are going to use it in control loops, between 3kHz and 5kHz sampling.

Between the main mode and the OIS mode, there are tons of ODR to choose from.

However, is there a way to make the ADC sample at EXACTLY 5kHz?? Like a triggered or synced ODR?
Or do I have to set the ODR at 7.68kHz and read the latest value from the FIFO and deal with the small discontinuities?

I see the Triggered-ODR section 6.6 in the datasheet. Does it means enabling this will sync the ADC with an external INT2 pulses? Does the new values appears in the FIFO after a defined short delay?

Thanks!
