摘　　要：经分析,手摇旋转编码器工作时,其两相输出信号是按照格雷码变化的为了有效地防止因信号抖动而引起的误计数,设计了一种按格雷码变化对手摇编码器进行计数的软件,该软件具有硬件电路简单,工作稳定性可靠等特点。By analyzing the working process of the hand rotary encoder, it is concluded that the two phases of output signals are changed in the light of gray code. To prevent the miscounting by the jitters of the signal, a counting software is designed for hand rotary encoder by the changes of gray code. The software possesses the characteristics of simple hardware circuit, stable and reliable work, etc.
