GGButton

Overview

Simple .wav player stylized on GGButton created on STM32 microcontroller(STM32F407VG).

Description

Usefullnes and simplicity was the main target in creating this project. Music files are stored on SD card and their number is limited to 8 due to 8 positon winder used in our model. Keep in mind that these files need to be named 0.WAV, 1.WAV [...] 7.WAV. SPI is used to comunicate SD module with STM32. Handling of our project is pretty straight forward - to play music push main button, to stop it push again. Twist winder to change song. To change audio volume, adjust potentiometer.

How to run

1.Hardware needed:

• STM32f4-DISCOVERY board,
• SD Card Module and SD Card formatted to FAT32,
• 1 switch,
• 1 rotating 8 position swith(alternatively 8 normal swithes),
• 1 rotary potentiometer,
• Headphones or loudspeaker with male jack connector.
