i recently bought a mpu 9150
its has a gyroscope accelometre and compass
idk how to use the first two but i want to use the compass
i made a program that reads the data coming from the compass and display them on the monitor and i got these reading
mx =-8 my = -70 mz =-32
where mx is the reading of x axis m y is reading of y axis etc
can u help me by telling me what are those readings? what do they efer to? degrees or something else? and how can a compass read the z axis?
how to turn them in a useful degrees?
