dear madmongo1 i just copy/pasted the example and modified nothing. please refer to following error message. 

Wow. It compiles without problems. but still i get intellisense error. Thank you so much madmongo1.

I would check the libftdi thanks. But libmpsse works fine only except for unable to change pin mode to input.

Thanks Mr. Winer But do you mean that it is supported in MPU6050 but not recommended? The calibrateMPU6050 method is pushing them to registers as shown below. If this works,...

Thanks Mr. Winer. I could find a document which confirms the MPU6050 has the hardware offset registers. https://www.digikey.com/en/pdf/i/invensense/mpu-hardware-offset-registers I would verify which works, thanks again.
