| Abstract: | Realization of music player by PLC is studied according to pulse output instruction and arithmetic application instruction of PLC.Coding and storing methods of music pitch and length are analyzed.Function of read note code is realized by using indirect addressing of PLC,and decoding is realized by using arithmetic instruction.Output function of different note frequencies are realized by SPED instruction,and different music lengths and beats are controlled by PULS instruction. |
