I'm using stm32f051R8Tx(stm32f0discovery) and I'm trying to connect with i2c devices

I used HAL-driver that CUBEMX provides and i succeeded  to communicate with i2c LCD device(LCD1602A).

LCD works really well.

However, I also used mpu6050, i2c gyro sensor, in a same code, I cannot get this thing work.

I used debug session and it seems like acknowledge problem.


there are some people who have similar issues and they solved this problem with shifting address to the left.

so I tried address left shifting as well but mine doesn't work. 


anybody can help?
