Hi Everyone,

I am new android platform. i am trying to interface MPU6050 gyroscope sensor to dragon board.
it has built in driver, i didn’t change anything in code. when i turn on it was present in sys/class/sensors directry but problem its not working in app (.apk file),means when i install sensor app it wont get any data.

  1. Is there anything need to change in nativesenormanger.cpp or other files…?
    please give me suggestion.

Thanks and Regards,

Hi
Chethan,

No there is no any change nativesenormanger.cpp.

Are you getting your driver is registered with input subsystem ?
You can check it through “getevent” command from adbshell.

As you said you haven’t changed anything in code so by default MPU6050 works as polling mode , so if your driver registered successfully than you will get continues data in “getevent” , Are you able to see it ?

Keval

Hi,

Please search for “android sensor porting” keywords, you have to implement HAL to make app works.
