I had to lay off the IMU for a while to work on other project, but good news is that I have the ADIS16488A working just about 100%. I am using a Raspberry Pi to communicate with the IMU and have no problems configuring the registers or reading data. The only problem I seem to be having is with the data ready signal; there doesn't seem to be much mention of it in the datasheet, and it is not resetting itself after I sample the data registers. I am only sampling the gyro and accelerometer registers; do I need to sample others to get this pin to reset?
