10. Memory Cards – FAT16
The Picaso Processor 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 Picaso Processor 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.
RMPET, a 4D Labs Tool found in the Workshop4 IDE, is
capable of repartitioning and formatting microSD
cards to be the appropriate type and format for 4D
Labs processors. This should be used for all cards.
Note: A SPI Compatible SDHC/SD/micro-SD card
MUST be used. Picaso along with other 4D Labs
Processors require SPI mode to communicate with
the SD card. If a non-SPI compatible SD card is used
then the processor will simply not be able to mount
the card.
11. Hardware Tools
The following hardware tools are required for full
control of the Picaso Processor.
11.1. Programming Tools
The 4D Programming Cable, uUSB-PA5 Programming
Adaptors, and gen4-PA (gen4 Programming Adaptor)
are essential hardware tools to program, customise
and test the Picaso Processor. Anyone of these can be
used.
The 4D programming interfaces are used to program a
new Firmware/PmmC, Display Driver and for
downloading compiled 4DGL code into the processor.
They even serve as an interface for communicating
serial data to the PC.
The 4D Programming Cable, uUSB-PA5 Programming
Adaptors, and gen4-PA are available from 4D Systems,
www.4dsystems.com.au
Using a non-4D programming interface could damage
your processor, and void your Warranty.
