I'm hoping that someone might be able to help with issues I'm having with the sense hat (before I sent them back)
Bit of back ground - I build a single axis (yaw) gyro system some years back (high quality gyro with dedicated amtel MPU for sampling. Sample rate 100Hz, averaging @ 10Hz). Repeat-ability approx 0.5 degrees or less, drift 1 deg/min.Reason I liked the idea of the hat was because of the IMU and thus cancelling out the drift.
Results so far have been very disappointing. Just testing the gyro a 360 yaw turn will yield about a 3-7 degree variance
Gyro drift is close to 1 degree/sec
Using the IMU (i.e. compass, accelerometer and gyro) repeat ability is improved but the lag is high to get a steady result.
I've tried with the stock RTIMULin.ini file as well a a number of calibrated ones.
I also found this link - but to no avail: viewtopic.php?f=104&t=110594
Are my expectations for this device simply to high? The application is robotics. Perhaps I should look else where?
I have checked all the common suspects (power etc). This is running jessie on a RPi 2
Thanks in advance for any advice
