This is a sample that drives a speaker with PWM. This sample will play a ".wav" file of the microSD or USB memory root folder. If the USER_BUTTON0 is pressed, the next song is played.
| Format | Wav file (RIFF format) ".wav" |
| Channel | 1ch and 2ch |
| Frequencies | 32kHz, 44.1kHz and 48kHz |
| Quantization bit rate | 8bits and 16bits |
You can adjust the volume by changing the following.
main.cpp
AudioPlayer.outputVolume(0.5); // Volume control (min:0.0 max:1.0)
The default setting of serial communication (baud rate etc.) in mbed is shown the following link.
Please refer to the link and change the settings of your PC terminal software.
The default value of baud rate in mbed is 9600, and this application uses baud rate 9600.
