hi .....

We are using ADIS 16405 IMU from Analog Devices in our application,we are using SPI interface for collecting the data from IMU.We are able to get the correct data but once in a while data shows 0x0000. Earlier we thought that it might be the problem with power glitches and used regulated 5v dc source but still the same problem is coming.we are operating the device with clock rate of 117.9647 k Hz,IMU in a slave mode and Master is ADSP 21262 DSP processor based kit .Please help us with this.

regards.......
