Hello everyone,
I was happy to have fixed my interference issue, but when I got home and
wanted to do some tests, the servos started acting crazy in AUTO 1 mode. I
looked at the PFD and it just goes in every direction very quickly. I
tried the different ahrs but it didn't really help.
I looked at the raw data, the accelerometer seemed fine. The gyroscope on
the other hand had values between 0 to 10000 while still.
Rotating the board 90, 180, -90, -180 as well as waiting steady for the
gyro to align helped a lot. However when letting the plane still for a long
time I can still see the gyro going off once in a while. I am afraid it'll
do the same in flight.
I saw that Luke had a similar issue but on a stm32 system:

I would like to try the same solution but I am not sure which function to
use on LPC21/umarim
