Design of simple electronic organ based on single chip microcomputer

摘要：

　　the electronic organ uses the STC89C52 microcontroller as the main control chip.It uses the 4 * 4 keyboard circuit mode to choose tones and tone value is displayed pitch by the common cathode LED digital tube display.It can use the independent key to play or pause music.The simple electronic organ has 16 tone and can play songs.The paper describes the generation principle of the tone and the style of the rhythm control.It produces how to use PROTEUS and KEIL software to carry out simulation and debugging.Through software design and hardware debug show that this system not only brings out playing musical composition basic function,but also its design is concise and is apt to understand.In this design,the result is good.
