Hi,
I bought a AltIMU-10 V5 board this past week. This is my first time working with an IMU device. I managed to get it hooked up to my Arduino UNO and I’m reading data from it. I’ve used the Calibrate sketch and entered the values in the MinIMU9AHRS sketch.
When I read the value from the Serial Monitor, I see the values changing when I move the board.
I modified the output.ino to display the MAG_Heading and this is where the problem comes in. The values doesn’t correspond with the actual headings I’m point the device in. Not even close. The values seem to vary from 26 to around 175. I even get some negative values.
I would like to use this as a tilt compensated compass to drive a Homebrew Satellite Tracking Antenna.
I’ve searched high and low on the internet, to find someone that has used this board in a similar compass project, but I had no luck.
