I'm trying to figure out what sort of jitter is normal for an LSM303DLHC. I'm getting a lot of jitter even using time averaging on my heading.
I'm using a breakout board from Pololu - LSM303DLHC 3D Compass and Accelerometer Carrier with Voltage Regulator.
Using the board with a 4.7uF capacitor I got the following results while the device was laying on my desk motionless (without a capacitor the values were horrible):
Heading:
Average 301.9728947
Min 300.56
Max 303.39
Variation 2.83
Averaged Heading:
Average 301.9869079
Min 301.5
Max 302.63
Variation1.13
Pitch:
Average 9.054078947
Min 8.52
Max 9.84
Variation 1.32
Roll:
Average -0.226973684
Min -0.68
Max 0.06
Variation 0.74
With only the included capacitor to the 3.3V regulator I got the following
Heading:
Average 137.3315566
Min 136.01
Max 143.6
Variation 7.59
Averaged Heading:
Average 137.3248585
Min 136.76
Max 138.33
Variation 1.57
Pitch:
Average 6.658301887
Min 2.93
Max 6.98
Variation 4.05
Roll:
Average 0.021698113
Min -1.14
Max 0.43
Variation 1.57
Any feedback on what is reasonable for jitter on a device that is sitting still?
