added function to block on the ring buffer until it es empty
made pointers volatile (fixes lock when in O3)
design cosmetics in the processing loop
completed MPU6050 register description
added function to initiate an I2C read transfer
added function to fetch the MPU configuration
added MPU6050 configuration fetch to main
added first two configuration values
added additional configuration functions
added interrupt handling for MPU6050
enabled MPU6050 data fetching
MPU6050: implemented actual data reading
MPU6050/MMA8451Q: added transmission of both data
MPU6050: not sure what is wrong, but bit 15 in Z acceleration high register is jumping
MPU6050: trying to find the Z axis bug
using the correct XOR in MATLAB helps, but does not solve the problem
the serial does not seem to be the issue
bumped to 230400 baud
MPU6050: now streaming at 200Hz
further reduced sample rates to 100 Hz
