The problem with readings DOUT from ADIS16365

Hi,

 

I have a problem with data being received from the sensor. I use to communicate via SPI with ADIS, using ioctl SPI. To receive data sent to it DOUT 0x3E00 frame. In our application we added a control bit errors, which in the case of the gyroscope and accelerometer is a 15 bit data each, according to specifications. In case of receiving a reply with the status data errors ignored them. By contrast directly with erroneous data frame is a frame appears with strange values (almost all zeros). These figures do not include error status, and we know for sure that they are wrong. We tried to increase / decrease the delay but it did not work. The specification also did not find information about the situation. Subsequent readings are correct.

 

What could be the reason of such data?

 

Regards,

Lukas
