Question about ADIS16209

Hi All,


ADIS16209 does not work well. The output data does not change when the ADIS is vibrated.

The SPI clock is set to 625kHz, the SMPL_PRD (0x36) is set to its default value (0x0014) and the AVG_CNT

is also set to its default value (0x0008). The DIO1 is set to as a data update trigger and it falls low level

every 25 msec. (0x04 @ 0x34) All setting value seem to be written successfully but read data does not change.

When the output data is updated? (When shoud I read the output data?) Currently I read the data after the DIO1

goes low level.

I also have attached initial setting and reading program. The reading program is run after the DIO1 goes low level.
