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.

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.
