Design of a simple electronic organ based on single chip
microcomputer
ABSTRACT
This design is the core content of simple electronic organ based on AT89C51 is designed. System by single chip microcomputer AT89C51, independent keyboard module, power amplification module, speaker, digital tube. Its software part mainly has the main program module, the module, keys module, display applications.
This design must first have a certain understanding of AT89C51, then according to the electronic organ functions produce hardware circuit and the programs are the source, finally carries on the simulation debugging. System with 10 independent key, including eight independent keys represent the eight notes, each key eight buttons in the digital tube will also corresponds to a character to indicate the user press the button, and two for the key button. Simultaneously this system also comes with a storage play the function of music, the user can press the function button to good songs, storage system will store the user program in the notes to play, in the process of automatic playback if press buttons on another function is the interrupt play songs. The design of the main advantage of the hardware circuit structure is simple to implement, electronic organ function basically, the system is stable and reliable.
Keywords: At89c51, electronic organ, playing, recording.
