Motor Speed Measurement Considerations When Using TMS320C24x DSPs
The TMS320C24x generation of DSPs provide appropriate internal hardware for interfacing with low-cost, external-speed sensors for motor speed measurement applications. The periodic output signal from the speed sensor is applied to the capture input pin of the DSP and the signal’s period is measured. This application report gives an analysis of the speed measurement system to show the effect of system parameters on the calculated speed.
