ADIS16405 IMU data reading

Started by Mamidipalli October 18, 2010
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.......

Did you check if your SPI interface is configured propely? Sometimes sampling on wrong clock edge works, but unreliably - like in your case... - while(1);
