基于STM32的PWM音乐播放器应用设计
Application Design of PWM Music Player Based on STM32
摘要
Abstract
Based on 32-bit STM32F103, using audio signals produced by PWM to drive a buzzer to play music, a music player is de- signed. The player can realize 21 scales from bass to treble and play complete songs according to music scores. Test results show that the output signals of PWM are consistent with the corresponding voice frequency of the scales, and the scheme is feasible. This method can also be used in motor control, keyboard design and so on, showing good practicality.关键词
