1. Description

The  uLCD-35DT  is  a  high  resolution  480x320  pixel
3.5” Intelligent Display Module powered by the 4D
Systems’ DIABLO16 Graphics Processor.

The uLCD-35DT is designed with versatility in mind,
allowing  for  either  cable  loom  connection*  or
direct PCB connection to a Host, enabling a  wider
range  of  customers  to  take  advantage  of  this
display module.

Driving  the  display  and  peripherals  is  the
DIABLO16 processor, a very capable and powerful
chip  which  enables  stand-alone  functionality,
programmed  using  the  4D  Systems  Workshop  4
IDE  Software.  The  Workshop  IDE  enables  graphic
solutions  to  be  constructed  rapidly  and  with  ease
due  to  its  design  being  solely  for  4D’s  graphics
processors.

The  DIABLO16  Processor  offers  considerable
FLASH  and  RAM  upgrades  over  the  PICASO
processor,  and  also  provides  mappable  functions
such  as  I2C,  SPI,  Serial,  PWM,  Pulse  Out,  and
Quadrature  Input,  to  various  GPIO,  and  also
provide up to 4 Analog Input channels.

The  display  module  has  an  array  of  features
including PWM for Sound, Touch Detection, micro-
SD memory storage, general purpose I/O including
Analog  Inputs,  multiple  TTL  Serial,  I2C  and  SPI
channels  and  multiple  millisecond  resolution
timers, amongst many more features.

Anything that has been designed in the past to run
on  a  PICASO  Processor  can  theoretically  run  on
this DIABLO16 Module with minor changes. Please
ensure you contact the 4D Systems’ support team
if unsure  if upgrading from a PICASO product and
wanting  to  design  with  or  change  over  to  this
uLCD-35DT Module.

NOTE *: Cable loom connection possible on special
order  only,  as  the  cable  loom  connectors  are  not
populated  by  default  on  the  uLCD-35DT  and  only
with  special  orders  subject  to  a  MOQ.  These  are
not  stocked  and  available  on  special  order
requests  only.  Please  contact  4D  Systems  Sales
department  if  you  require  customised  modules
with these headers populated.
