ims330dlc Gyro signals

[fredschoville]

Hi

Does anyone know how to stabilize the gyroscope and accelerometer signals. I am getting signals back but I am trying to move a radio button on a bullseye and can't seem to smooth out the signal. I am using I2C communications.

Have look at:

MotionAC
MotionMC
MotionGR
MotionFX

There are other Motion* products - it will depend on your precise needs.

Hi ​@fredschoville 

I would recommend calibrating the IMU first and then applying sensor fusion, as suggested by ​@codebuk , and filtering, rather than using the raw accelerometer/gyroscope data directly. A complementary filter, together with gyro bias compensation, a small deadband, and a fixed sampling rate, usually helps reduce jitter significantly. In most cases, I2C is not the main issue unless the timing or reads are inconsistent.
