Re: Problem:i cannot get the right data from the ADIS16448 when it is waggled

SMPL_PRD's value is 0x0B01, SENS_AVG's is 0x0402.

The ADIS16448 is an autonomous system that requires no user  initialization. When it has a valid power supply, it initializes itself  and starts sampling, processing, and loading sensor data into the output registers at a sample rate of 819.2 SPS(from the datasheet). I cann't understand this sentence, when the device is powered, the SMPL_PRD's value should be the default. What's wrong?

 

Another question:for example, set SMPL_PRD[15:8] = 0x04 (DIN = 0xB704) to set the decimation factor to 16.

How to get 0xB704 according to the base address and the value of SMPL_PRD that i want to set? Thanks a lot.
