Issue communications

Also try avoiding reading a single byte, minimum two, it is another errata of the F1 I2C.

Finally, I am able to read correct data, and write to configuration registers of the MPU6050 module.

The only difference between my working code and earlier code is that earlier, I was trying to read WHO_AM_I byte (single byte read operation) at startup, which froze the I2C driver, hence making later transactions fail.

Now I am reading the sensor data in burst mode (14 registers at once starting at 0x3B). It's working as expected. To read a single byte, I read multiple bytes and discard the extra data.
