If you - find it useful you can buy me a beer some time. - - Demonstrate MPU-6050 basic functionality including initialization, accelerometer trimming, sleep mode functionality as well as - parameterizing the register addresses. Added display functions to allow display to on breadboard monitor. - No DMP use. We just want to get out the accelerations, temperature, and gyro readings. - - SDA and SCL should have external pull-up resistors (to 3.3V). - 10k resistors worked for me.
