Hello @all,
I am trying to implement a magnetic compass using magnetometer and
accelerometer device drivers. But here i need to use a sin, cos, atan in
order to get the orientation values. Can anyone tell me how can i get them
implemented. Because i guess there is no math.h available at kernel level
(even at HAL also) .
Thanks for your help in advance
