Re: How to measure low velocity

Some body tell me to change the ADC with higher resolution e.g 12 bits or 14 bits...This may help me to know if having a small change in input voltage from zero point voltage which means having a very slow rotation.
But I wonder if anybody use 10 bit ADC and still measure angular exactly.My purpose is that if the system (with ADXRS on it) rotate, I have to control it to turn back to the starting point exactly.
Is changing ADC is a good idea, because it's expensive to have high resolution ADC and waste time to re write program for another one.
