The Flight Controller firmware comes with a set of default constants for the accelerometer to use. By following this procedure, you will move your ELEV-8 v3 in a series of positions as prompted by the Ground Station software. When completed, the GroundStation software uploads constants to the Flight Controller's EEPROM. Then, the firmware will use these constants, specific to your very own ELEV-8 Flight Controller, instead of the defaults while flying. This will improve overall flight performance.
Reloading the ELEV-8 Flight Controller firmware will not over-write the calibration settings you create with this procedure. To completely erase these (caution - and all!) calibration settings, see the Factory Default option under the System Setup tab.
In the Ground Station software, click on the “Accel Calibration” Tab. You should see this screen:
It is important for the ELEV-8 to remain absolutely still during calibration - slamming doors or someone walking around and shaking the floor can create enough vibration to throw off the calibration.
You will be taking 4 readings, rotating the ELEV-8 v3 one-quarter turn (90º) between each reading:
The ELEV-8 Flight Controller will beep to confirm that the accelerometer has been calibrated.
