Hi Everyone,

I am trying to read temperature value from MPU6050 sensor. I could not read it. I tried to read WHO_AM_I signal, I could'nt read it as well. Value should be 114 but i am getting 5.

Does anyone has any idea what to check, how to fix? I am using STM32 Nucleo board.

Thank you.

Regards
