I am planning to use ADIS16485 IMU for Gyrocompassing. I hooked up the ADIS16485 to a microcontroller and I was reading Z_GYRO_OUT register value. According to the data sheet to convert Z_GYRO_OUT register value to engineering value I need to multiply it with 0.02. Now I want to improve the accuracy of my data and want to use Z_GYRO_LOW register value also. In data sheet it says MSB has a weight of 0.01 and every subsequent bits weight is half of the previous one. I might sound naive but how do I exactly convert the Z_GYRO_LOW register value to engineering value and combine that with the value from Z_GYRO_OUT register. Is there a equation I can use? I would appreciate any help in this matter.
