I attached Ultrasonic Sensor and gimbal servo on my S550 Copter.
the servo will fix sensor’s direction when drone tilt forward when it is flying.
So I must get drone’s AHRS Data(Pitch Angle)
So I uploaded AHRS_test.pde to APM board.
I successfully uploaded and tested several example sketch file on the APM Board
but this time I met error.
I never touched one line of source code of the example sketchs but It genereated error.
error message says
class_ap_inertialsensor_MPU6000 has no member named ‘init’
class_ap_inertialsensor_MPU6000 has no member named ‘init_accel’
I’m stuck in this error message along the day and still dont have a clue.
I searched google and forums but it is hard to find the solution…
