| Abstract: | The operating theory of quadrature-encoder pulse (QEP) circuit and capture unit , interface circuit and software of high accuracy measurement of rotational speed and angle using DSP TMS320F2812 are discussed. The proposed method ensure synchronous counting for time and pulse. Its realiability and accuracy are veritified by the experiment result , and it is applicable to wide speed range and have high immunity. |
