 FIRST is definitely worth any amount of money any company gives. FIRST really puts on good events for us, and I can see where the money is going. - RBrandy [more] |

Calibrating Devantech cmps03
Hey all.
We purchased the devantech cmps03 for use on an autonomous outdoor robot for navigation purposes. We have wired it up as per directions and gotten readings by timing the pwm pulses. However, we are supposed to get readings within 3 or 4 degrees, but our readings are way off. They are pretty constant, but not at all the true direction. We figure this is due to calibration. We followed the calibration directions in the manual and used the pin method. This changed the readings that the compass gave, but they are still highly inaccurate. We are aware that tilt affects the compass readings and make sure to keep it level at all times. Are there any suggestions as to how to calibrate the compass? Thanks |
