Electronic Compass
In the
winter i spent time to test a sensor BNO055. This was a success it works from
start, has built in tilt compensating and calibration. Only a few rows of code.
It has two register to read the current
calibration state for system all sensors and magnetic sensors all values > 0, gives correct directions.
Above photo,
first digit is magnetic sensor status second is system status 0 – 3. My next try
vas to integrated with Fox receiver and it also works., no effect of metal box.
I also try
a sensor LMS303, but this this I can’t get to work. I has cod to make tilt compensation and
calibration. It doesn’t give me 180 deg.
Difference from N to S direction and also W – E so I lev it for now.
The BNO055
has been on two competitions, and the first direction after start was tree spot
on and the other 2 just a few degrees off, it was a 80m fox-run.
