Hi,
I just started to test MPU9250.
When reading the MPU9250's Register Map, in page 13, it is about how to config DLPF.
There are somethings that I don't figure it out.
In the middle portion of Page 13, it says:
The DLPF is configured by DLPF_CFG, when FCHOICE_B [1:0] = 2b’00. The gyroscope and temperature sensor are filtered according to the value of DLPF_CFG and FCHOICE_B as shown in the table below. Note that FCHOICE mentioned in the table below is the inverted value of FCHOICE_B (e.g. FCHOICE=2b’00 is same as FCHOICE_B=2b’11).Which register should I put the FCHOICE value to ?
Or, I use the inverted value of FCHOICE and put it to register 27 bit[1:0] (fchoice_b) ?
