Audio playback support in the
PICASO Processor enables the
µLCD-28PTU module to play audio
WAV files stored in the micro-SD
memory card. PWM and an on-
board audio amplifier with 8Ω
speaker ensure ample audio
output capability. A simple
instruction enables the user to
play/pause/stop audio files while
continuing the execution of the
users code, such as display
updates, touch recognition,
communications, etc. The audio
system also allows real time pitch
change of audio samples.
