8- Monophonic Stand-Alone Mode 7 - Music Player:
8.1- Interface:
SmartWAV 2 could be connected as a Stand-Alone module without
the need of an external host controller, in this fashion the processor
can be triggered and controlled with external push buttons
connected to the board inputs. The processor can be used as a
battery powered system due to the ultra-low power consumption and
the sleep/stand-by modes.
In Stand-Alone Modes, the SmartWAV 2 only recognize .wav files
stored in the root path of the microSD card, all .wav files must be
placed in this path.
