Wave player using PIC18F4550 microcontroller

Making an audio player (.wav files) using PIC microcontroller is not complicated especially when the MCU has a PWM module. This topic shows how to build an audio player using PIC18F4550 microcontroller where the the file is stored in an SD card with FAT16 or FAT32 file system. In this project I used a wave file with sample rate of 16000 Hz and 2 channels (stereo). The file I used originally it was an MP3 fi ...
