microVGA – VGA GRAPHICS ENGINE
Audio 6.3.
Audio playback support in the PICASO Processor
enables the μVGA-III module to play WAV audio at
Line Levels to a pin on the expansion header. 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.
For a complete list of audio commands please
refer to the separate document titled:
“PICASO-4DGL-Internal-Functions.pdf”
SD/SDHC Memory Cards 6.4.
The module supports micro-SD memory cards via
the on-board micro-SD
connector. The memory
card is used for all
multimedia file retrieval
such as images,
animations and movie
clips. The memory card can also be used as general
purpose storage for data logging applications.
Support is available for off the shelf micro-SD and
high capacity HC memory cards (4GB and above).
FAT16
6.5.
The μVGA-III uses off the shelf standard
SDHC/SD/micro-SD memory cards with up to 2GB
capacity usable with FAT16 formatting. For any
FAT file related operations, before the memory
card can be used it must first be formatted with
FAT16 option. The formatting of the card can be
done on any PC system with a card reader. Select
the appropriate drive and choose the FAT16 (or
just FAT in some systems) option when formatting.
The card is now ready to be used in the PICASO
based application.
The μVGA-III also supports high capacity HC
memory cards (4GB and above). The available
capacity of SD-HC cards varies according to the
way the card is partitioned and the commands
used to access it.
The FAT partition is always first (if it exists) and can
be up to the maximum size permitted by FAT16.
Windows 7 will format FAT16 up to 4GB. Windows
XP will format FAT16 up to 2GB and the Windows
XP command prompt will format FAT16 up to 4GB.
