Topic: MPU-6050 stops or gives random values after a small hit. (Read 1 time) previous topic - next topic


Hello, I'm using this sensor (MPU-6050 6DOF) for my final project. The idea is to create a 3D colour picker with processing. It's fitted into a box that it's moved with the hand. I have almost everything working except for the arduino's side.

I started with the dmp code of Jeff Rowberg http://github.com/jrowberg/i2cdevlib/blob/master/Arduino/MPU6050/Examples/MPU6050_DMP6/MPU6050_DMP6.ino using it as a camera so you can see all the RGB cube. After struggling a little bit I managed to implement the gyroscope as a camera. The problem came when I noticed that suddenly it stops, or starts to turn more fast than graphics can handle even being still.

I realized it was when I left it at the table with some energy. So the thing is that it happens after a small (really small) hit. Each time it's worse.
It gives null pointer exception.

I have two possible theories:
- One is that is a peak of information that cannot be handled,
- and the other is that the hardware (the sensor) it's too sensitive even for that type of application.

Any help will be welcome, I know how to create the problem, but no how to solve.

BTW, any ideas why after a several runs of the processing code it gaves:

Error inside Serial.write()

and I can only solve it by rebooting the computer.


When I setup the wiring I run out of wire and used another type, a slightly smaller wire that didn't make good connection when it had a small hit.
