Issues with UNO

[letaureau]

Code is working fine on Mega2560 but when using the code and/or i2c scanner code on Uno with SDA and SCL connected to A4 and A5 respectively.. they are failing to detect the device

Well I cannot comment on the i2c scanner, however i2c scanner should be the first thing to get working before trying with the motion sensor example.
This sounds like wiring issue.

Hi,
I am using Arduino Uno with MPU 6500. I followed your post in arduino forum: http://forum.arduino.cc/index.php?topic=242335.msg2143134#msg2143134 You suggested changing MPU6500_MEM_REV_ADDR from 0x17 to 0x16. I did, but it doesn't work still.
