Accelerometer:
An accelerometer is a device that measures proper acceleration ("g-force"). Proper acceleration is not the same as coordinate acceleration (rate of change of velocity).
For example, an accelerometer at rest on the surface of the Earth will measure an acceleration g= 9.81 m/s2 straight upwards. By contrast, accelerometers in free fall (falling toward the center of the Earth at a rate of about 9.81 m/s2) will measure zero.
Introduction:
My goal is analyzing vibration waves using an accelerometer and fourier analizis (Matlab) can observe the behavior of waves in time.

Application:
The C2000, communicates with the PC via a serial environment using a protocol number in Hexadecimal, as this greatly reduces the number of bytes to send, when compared with a protocol of numbers in decimal; by making more efficient communication between the PC and C2000.
