I worked out on a library for UART debug and I2C basics to read write registers via I2C..problem now is I read the  FIFO but it turns out to be zero..Disabled sleep bit..Fifo Enable Register Set, User Control Register set too..but still no readings.

Hi,

Which board are you using for MPU6050. As this chip comes in QFN package, so please verify if it is soldered accurately(not dry soldered pins) on PCB.Then see if you are passing correct addresses to access the FIFOs. Check ACK from chip.I have worked with the same chip.
