Verify operation of the accelerometer

[pachucho1024]

Hello friends

I can not blow my quadricopter in any way. The problem is that after starting, the minimum speed motors accelerate randomly (calibrated on a table). I thought it could be because of the vibrations, but if I cut the sensors and leave on the table is the same.

I can not try to take off. I think the accelerometer is not working well and responds to accelerations that do not happen.

Using original wmp and nunchuk, I'm testing with versions 1.9 and 2.0, I'm using arduino mini pro.

Does anyone know how to test the accelerometer?

Could affect the ESC will be of different brand?

Thank you.

Do you have common ground on everything?
Otherwise you can get same effect.

How should be the sensor axis directions

TILT the MULTI to the RIGHT (left side up):
•MAG_ROLL, ACC_ROLL and GYRO_ROLL goes up
•MAG_Z and ACC_Z goes down

TILT the MULTI forward (tail up):
•MAG_PITCH, ACC_PITCH and GYRO_PITCH goes up
•MAG_Z and ACC_Z goes down

Rotating the copter clockwise (YAW):
•GYRO_YAW goes up

The copter stays level:
•MAG_Z is positive ; ACC_Z is positive

which brand is it ?

Hi PatrikE, I am giving the war .... Thanks for your constant help.
Connect land as the following scheme:

Connect the negative of the accelerometer to wmp, all the accelerometer connections go to wmp.

As the scheme connect the negative of the sensors and arduino to the negative of an ESC, but not the negative that feeds the engine (the battery), I connect the negative cable supplying the arduino (3 thin wires: 1 data to arduino, 1 current (5V) arduino, 1 negative) but one ESC, the negative of the other three are not connected

Do I have to connect together all negative?

Fr3d hello, thanks for helping

the orientation of my sensors is:

In this forum a colleague told me that version 2.0 for the orientation of the sensors changes. I would need pictures to know how to guide them, because I do not understand "ACC_PITCH and GYRO_PITCH goes up". For all that do testing with version 1.9, which I think is the same orientation as the previous image.

Using accelerometer original wmp original.

Would you know you if the orientation of the image works for version 1.9?
