Hi,
@CapnKernel: I´ll mount my IMU-module as you describe and with x-axis points to the direction of the boat. This works here at home on the table at it´s best.
Regards
Andreas

Hi,
The IMU works in 3D and fortunately because the Earth's magnetic field is closer to the vertical than to the horizontal (60 degrees here). The most important thing is to calibrate the vertical correctly so that the calculation of the compass heading is correct. With Pypilot, level calibration is easy and the heading is correct in all conditions.

the advantage of aligning the compass is that pitch and roll are not interchanged and the compass gives absolute readings. For relative compass heading which is good enough to hold a course, only level alignment is needed.

"The backlight from display is powered by 3,3V and is dimmed down with a 2,5k resistor. This is ok for night viewing and not to bright."
Would it be possible to use a/the setting in the menu for the blacklight from a GPIO?
And I would like to have a red light burning when AUTO is active?

the backlight does not turn on and off with auto, it is a user set pwm modulated value and on or off based on the light sensor.
