【Abstract】 In this paper a method of measuring rotation speeds of DC micromotors with Z-80 single board computer is presented. Without any additional sensor, and detecting pulse signals from the current waveform directly, the method can be conveniently used. By the step of reducing the affect of quantization error, the precision of the measurement is higher.更多还原
