uLCD-43DT Display Module
1. Description
The uLCD-43D/DT/DCT is an upgrade to the
favourite uLCD-43P/PT/PCT range of 4.3”
Intelligent Display Modules, now powered by the
4D Systems’ DIABLO16 Graphics Processor.
The uLCD-43D/DT/DCT intelligent display modules
are designed for applications demanding a good
sized intelligent display module, and where
performance is important, along with a good
amount of Flash and RAM.
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 or uLCD-43P/PT/PCT
intelligent display 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-43D/DT/DCT Module.
A table in included in this datasheet to outline the
main differences between the uLCD-43P versions
and the uLCD-43D version.

uLCD-43DT Display Module
4. Hardware Interface - Pins
The uLCD-43D/DT/DCT Module provides both a
hardware and software interface. This section
describes in detail the hardware interface pins of
the device.
Serial Ports – TTL Level Serial 4.1.
The DIABLO16 Processor has three hardware
asynchronous serial ports (COM1 – COM3) that
can be configured on a variety of the processors
GPIO pins. TX/RX0 (COM0) is dedicated and its
pins are fixed. All of the DIABLO16’s serial ports
can be used to communicate with external serial
devices.
TX/RX0 are referred to as COM0, and is the only
one used for programming the DIABLO16 itself.
The primary features are:
Full-Duplex 8 bit data transmission and
reception.
Data format: 8 bits, No Parity, 1 Stop bit.
Independent Baud rates from 300 baud
up to 600K baud.
Single byte transmits and receives or a
fully buffered service. The buffered
service feature runs in the background
capturing and buffering serial data
without the user application having to
constantly poll any of the serial ports. This
frees up the application to service other
tasks.
A single byte serial transmission consists of the
start bit, 8-bits of data followed by the stop bit.
The start bit is always 0, while a stop bit is always
1. The LSB (Least Significant Bit, Bit 0) is sent out
first following the start bit. Figure below shows a
single byte transmission timing diagram.
COM0 is also the primary interface for 4DGL User
program downloads, and configuration PmmC
programming. Once the compiled 4DGL
application program (EVE byte-code) is
downloaded and the user code starts executing,
the serial port is then available to the user
application. Refer to Section 5 for more details on
PmmC/Firmware programming.

J1 Pin 16, J2 Pin 9/10:
Module Master Reset pin. An active low pulse of
greater than 2μs will reset the module. Internally
pulled up to 3.3V via a 10K resistor. Only use open
collector type circuits to reset the device if an
external reset is required.
AUDENB (Audio Enable Output)
J1 Pin 2:
Output dedicated to enable or disable and
external amplifier, where required. Active Low.
AUDIO (PWM Audio Input/Output)
J1 Pin 14:
Universal Input or Output specifically for Audio.
This pin connects directly into the on-board
amplifier, but also with the filtered PWM output
from the DIABLO16 Processor. This pin can be used
to input a signal into the on-board amplifier to
play audio from an external device using the on-
board amplifier, or as a line-level output to drive
an external amplifier with DIABLO16 generated
Audio. Note that AUDENB must be enabled (low)
in DIABLO16 for any input signal to be heard.
Alternate Pin Funtions - Overview
Most of the GPIO pins have an alternate function
other than being for General Purpose I/O.
GPIO pins can be configured to be SPI, I2C, Serial or
a range of other functions.
Note: Not all pins however can be configured to
be any of the alternate pin functions.

Note: The additional SPI channel (SPI0) is
dedicated to memory cards and cannot be
reconfigured for alternate uses.
To map an SPI channel to a set of GPIO pins, the
following 4DGL functions are used:
SPIx_SCK_pin(pin); // Map the SCK pin
SPIx_SDI_pin(pin); // Map the SDI pin
SPIx_SDO_pin(pin); // Map the SDO pin
Where ‘SPIx’ is substituted with SPI1, SPI2 or SPI3
accordingly, and ‘pin’ is the target GPIO pin
compatible with that particular pin function.

uLCD-43DT Display Module
Chip Select for use with SPI can be any other
unused GPIO pin, configured as a Digital Output.
The lowering and raising of the selected CS (GPIO)
pin is done manually by the user is the 4DGL
application.
Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on how to use the SPI functions, along
with the separate document titled ‘DIABLO16-
Processor-Datasheet-REVx.x.pdf’.
I2C 4.6.
There are 3 user configurable I2C channels
available for mapping to GPIO, for use by the user
for the target application. All 3 I2C channels are
Master only, and cannot be configured to be
slaves at this time.
Please refer to the table on the previous page for
details on which GPIO can be configured for I2C.
To map an I2C Channel to a set of GPIO pins, the
following 4DGL function is used:
I2Cx_Open(Speed, SCLpin, SDApin);
Where ‘I2Cx’ is substituted with I2C1, I2C2 or I2C3
accordingly, ‘Speed’ is the desired I2C Bus speed,
and ‘SCLpin’ and ‘SDApin’ are the target GPIO pins
compatible with that particular pin function.
Note: The normal I2C pins are PA0 to PA13,
however use of these pins has a few limitations.
a) There is no slew rate control at I2C_MED
b) I2C_FAST is not truly 1MHz.
If either of these restrictions need to be
addressed, a special case of SCLpin = PA14 and
SDApin = PA15 exists ONLY for speeds I2C_MED
(which uses slew rate control) and I2C_FAST
(which is truly 1MHz)
Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on how to use the I2C functions, along
with the separate document titled ‘DIABLO16-
Processor-Datasheet-REVx.x.pdf’.
Pulse Out 4.7.
Pulse Out is used to create a single pulse of set
duration on the selected pin of choice, which is
inverted in polarity to the current state of the pin.
This ‘inversion of polarity’ means if a Pin is
currently held HI, and Pulse Out is executed on
that Pin, the pin will pulse LO and then return to
HI. Same with vice versa, if currently LO and Pulse
Out is executed on that Pin, it will pulse HI and
then return to LO.
This is available in both blocking and non-blocking
versions.
Please refer to the table on the previous page for
details on which GPIO can be configured to this.
Note: Each Pulse Out request needs at least a 1ms
lead time due to the scheduling of the event with
the internal 1ms timer.
To enable the Pulse Out function on a GPIO pin,
the following 4DGL functions are used:
pin_Pulseout(pin, value); //Non-Blocking
pin_PulseoutB(pin, value); //Blocking
Where ‘pin’ is the target GPIO pin compatible with
that particular pin function, and ‘value’ is the
length of the pulse in milliseconds.
Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on how to use the Pulse Out
functions, along with the separate document titled
‘DIABLO16-Processor-Datasheet-REVx.x.pdf’.
PWM Out 4.8.
There are 6 PWM channels available to be
configured by the user, with 4 time bases available
for selection.
The PWM can be configured to be used in Servo
Mode, or Simple Mode.
Please refer to the table on the previous page for
details on which GPIO can be configured for PWM.
Servo Mode allows a millisecond input value with
0.01ms resolution, which runs at a frequency of
approximately 50Hz or 50pps (20ms). The position
of the servo is determined by the width of the
pulse. Generally 1.5ms is 90 degrees, 1ms being 0
degrees and 2ms being 180 degrees. Servos
however vary, and the DIABLO16 PWM control can
be adjusted to suit most applications.
Simple Mode allows a percentage input value with
resolution of 0.1%, which runs at a frequency of
approximately 70KHz.
4D SYSTEMS uLCD-43DT Display Module
© 2014 4D SYSTEMS Page 12 of 24 www.4dsystems.com.au
uLCD-43DT Display Module
To enable the PWM output on a GPIO pin, the
following 4DGL function is used:
PWM_Init(pin, mode, value);
Where ‘pin’ is the GPIO compatible with the
particular pin function, ‘mode’ is the type of PWM
to generate, and ‘value’ is the parameter which
defined the PWM pulse itself.
Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on how to use the PWM functions,
along with the separate document titled
‘DIABLO16-Processor-Datasheet-REVx.x.pdf’.
Pin Counter 4.9.
There are 6 Pin Counter channels available to be
configured by the user, used to count incoming
pulses with the ability to call a user function on
overflow. The Pin Counter function is available for
use in a variety of modes.
The counters can be read and written at any time.
Please refer to the table in section 4.4 ‘Alternate
Pin Functions – Overview’ for details on which
GPIO can be configured for this.
To enable the Pin Counter function on a GPIO pin,
the following 4DGL function is used:
pin_Counter(pin, mode, OVFfunction);
Where ‘pin’ is the GPIO pin compatible with this
particular function, ‘mode’ is the type of trigger
used to count on such as Rising/Falling/Edge, and
‘OVFfunction’ is the user function to call when the
counter overflows, if desired.
Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on how to use the Pin Counter
functions, along with the separate document titled
‘DIABLO16-Processor-Datasheet-REVx.x.pdf’.
Quadrature In 4.10.
There are two Quadrature Input channels available
on the DIABLO16 processor, which requires 2 GPIO
pins each.
Please refer to the table on the previous page for
details on which GPIO can be configured for
Quadrature Input.
Quadrature Input allows a quadrature encoder to
be connected, and the position counter and delta
counter can be read at any time.
To enable the Quadrature Input function on a set
of GPIO pins (2 pins required), the following 4DGL
function is used:
Qencoderx(PHApin, PHBpin, mode);
Where ‘Qencoderx’ is substituted for Quencoder1
or Quencoder2 accordingly, ‘PHApin’ is the pin
connected to the A Phase of the Encoder, ‘PHBpin’
is the pin connected to the B Phase of the Encoder,
and ‘mode’ is not currently used so is to be set to
zero (0).
Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on how to use the Quadrature Input
functions, along with the separate document titled
‘DIABLO16-Processor-Datasheet-REVx.x.pdf’.
Analog Inputs 4.11.
Please refer to the table in section 4.2 for details
on which GPIO can be configured to be analog
inputs.
The analog inputs on the DIABLO16 have a range
of 0 to 3.3V, each with a max resolution of 12-bits.
The analog inputs can be read using three modes,
standard mode, averaged mode or high speed
mode.
Standard Mode results in a sample being
immediately read. Standard Mode can read over
40000 values per second. Operates at 12-bit.
Averaged Mode results in a 16 sample being
immediately read and their average returned.
Averaged Mode can read approximately 20000
values per second. Operates at 12-bit.
Highspeed Mode collects a user specified number
of samples at a user specified rate/frequency and
can execute a user function when complete. The
updated value updates approximately 250000
times across 1-4 channels. Operates at 10-bit.
To enable a GPIO to be used as an Analog Input for
Standard or Averaged modes, the following 4DGL
function is used to set the pin:
pin_Set(mode, pin);
4D SYSTEMS uLCD-43DT Display Module
© 2014 4D SYSTEMS Page 13 of 24 www.4dsystems.com.au
uLCD-43DT Display Module
Where ‘mode’ is the desired mode defined above,
either Standard or Averaged, and ‘pin’ is the GPIO
compatible with this function which is to become
an Analog Input.
For highspeed mode, the following 4DGL function
is used to set the pin and define the parameters:
ana_HS(rate, samples, 1buf, 2buf, 3buf, 4buf, func);
Where ‘rate’ is the number of samples per second,
‘samples’ is the number of samples to collect per
channel, ‘1buf’ ‘4buf’ are the buffer addresses
for the 4 channels, and ‘func’ is the user function
to call when the number of samples specified have
been collected.
Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on the Analog Input functions, along
with the separate document titled ‘DIABLO16-
Processor-Datasheet-REVx.x.pdf’.
5. PmmC/Firmware Programming
The DIABLO16 processor is a custom graphics
processor. All functionality including the high level
commands are built into the chip. This chip level
configuration is available as a PmmC (Personality-
module-micro-Code) file, which can be likened to
traditional Firmware. There is also a Display Driver
file, which separates specific display settings from
the PmmC, unlike on the PICASO processor where
everything is combined.
A PmmC file contains all of the low level micro-
code information (analogy of that of a soft silicon)
which define the characteristics and functionality
of the device. The ability of programming the
device with a PmmC file provides an extremely
flexible method of customising as well as
upgrading it with future enhancements.
The Display Driver contains the initialisation and
parameters associated with the particular display
that is to be connected to the DIABLO16
processor.
The PmmC file and Display Driver file can only be
programmed into the device via the COM0 serial
port with the aid of Workshop 4, the 4D Systems
IDE software.
Using a non-4D programming interface could
damage your module, and void your Warranty.

DIABLO16 Processor 6.2.
The module is designed around the DIABLO16
Graphics Controller from 4D-Labs.
The DIABLO16 is a smart Controller and the
interface to the TFT- LCD displays is almost plug-n-
play.
All of the data and control signals are provided by
the chip to interface directly to the display.
Powerful graphics, text, image, animation and
countless more features are built right inside the
chip.
The data sheet for the processor is available from
the http://www.4dsystems.com.au website:
“DIABLO16-Processor-Datasheet-REVx.pdf”
Audio 6.3.
Audio playback support in the DIABLO16 Processor
enables the uLCD-43D/DT/DCT module to play
audio WAV files stored in the micro-SD memory
card. PWM and an on-board audio amplifier with
8Ω speaker ensure ample audio output capability.
A simple instruction enables the user to
play/pause/stop audio files while continuing the
execution of the user application 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:
“DIABLO16-4DGL-Internal-Functions.pdf”
Note: The on-board speaker is a small device
designed to project into an audio cavity. It is not
very loud by itself. To enable louder audio, it is
recommended to use a larger external 8Ω speaker.
See the ‘Hardware Interface Pins’ – ‘System Pins’
section for more information.
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 (< 4GB) and high
capacity HC memory cards (4GB and above).
Note: A microSD card capable of SPI is a
requirement for all 4D Systems’ display modules
powered by Goldelox, Picaso or Diablo16
Processors. If a non-SPI compatible card is used, it
will simply fail to mount, or may cause
intermittent issues resulting in lock ups and
crashing of the application. Please refer to the 4D
Systems website for microSD cards offered by 4D
Systems.
4D SYSTEMS uLCD-43DT Display Module

uLCD-43DT Display Module
FAT16 6.5.
The uLCD-43D/DT/DCT Module uses off the shelf
standard SDHC/SD/micro-SD memory cards (SPI
Compatible Only) with up to 4GB 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 DIABLO16 based
application.
The DIABLO16 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. Refer to the 4D
Systems RMPET tool in the Workshop4 IDE.
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.
7. Display Precautions
• Avoid having to display the same image/object
on the screen for lengthy periods of time. This will
cause a burn-in which is a common problem with
all types of display technologies. Blank the screen
after a while or dim it very low by adjusting the
contrast. Better still; implement a screen saver
feature.
• Moisture and water can damage the display.
Moisture on the surface of a powered display will
cause the electrodes to corrode. Wipe off any
moisture gently or let the display dry before usage.
• Dirt from fingerprint oil and fat can easily stain
the surface of the display. Gently wipe off any
stains with a soft lint-free cloth.
• The performance of the display will degrade
under high temperature and humidity. Avoid such
conditions when storing.
• Do not tamper with the display flex cable that is
connected to the control board. This may affect
the connection between the display and the
driving circuitry and cause failure.
• Displays are susceptible to mechanical shock and
any force exerted on the module may result in
deformed zebra stripes, a cracked display cell and
broken backlight
• Always use the mounting holes on the module's
corner plates to mount the display.
8. Hardware Tools
The following hardware tools are required for full
control of the uLCD-43D/DT/DCT module.
4D Programming Cable/Adaptor 8.1.
The 4D Programming Cable and uUSB-PA5
Programming Adaptor are essential hardware
tools to program, customise and test the
DIABLO16 Processor.
Either the 4D Programming Cable or the uUSB-PA5
Programming Adaptor 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 and uUSB-PA5
Programming Adaptor are available from 4D
Systems, www.4dsystems.com.au
Using a non-4D programming interface could
damage your processor, and void your Warranty.

9. 4DGL - Software Language
The uLCD-43D/DT/DCT Module utilises the
DIABLO16 processor, which belongs to a family of
processors powered by a highly optimised soft
core virtual engine, EVE (Extensible Virtual Engine).
EVE is a proprietary, high performance virtual-
machine with an extensive byte-code instruction
set optimised to execute compiled 4DGL
programs. 4DGL (4D Graphics Language) was
specifically developed from ground up for the EVE
engine core. It is a high level language which is
easy to learn and simple to understand yet
powerful enough to tackle many embedded
graphics applications.
4DGL is a graphics oriented language allowing
rapid application development, and the syntax
structure was designed using elements of popular
languages such as C, Basic, Pascal and others.
Programmers familiar with these languages will
feel right at home with 4DGL. It includes many
familiar instructions such as IF..ELSE..ENDIF,
WHILE..WEND, REPEAT..UNTIL, GOSUB..ENDSUB,
GOTO, PRINT as well as some specialised
instructions SERIN, SEROUT, GFX_LINE,
GFX_CIRCLE and many more.
For detailed information pertaining to the 4DGL
language, please refer to the following documents:
“4DGL-Programmers-Reference-Manual.pdf”
“DIABLO16-4DGL-Internal-Functions.pdf”
To assist with the development of 4DGL
applications, the Workshop 4 IDE combines a full-
featured editor, a compiler, a linker and a down-
loader into a single PC-based application. It's all
you need to code, test and run your applications.
4DGL is available to be written in two of the four
environments offered by the Workshop 4 IDE,
Designer and ViSi.
10. 4D Systems - Workshop 4 IDE
Workshop 4 is a comprehensive software IDE that
provides an integrated software development
platform for all of the 4D family of processors and
modules. The IDE combines the Editor, Compiler,
Linker and Downloader to develop complete 4DGL
application code. All user application code is
developed within the Workshop 4 IDE.
The Workshop 4 IDE supports multiple
development environments for the user, to cater
for different user requirements and skill level.
The Designer environment enables the user to
write 4DGL code in its natural form to
program the uLCD-43D/DT/DCT Module.
A visual programming experience, suitably
called ViSi, enables drag-and-drop type
placement of objects to assist with 4DGL code
generation and allows the user to visualise
how the display will look while being
developed.
An advanced environment called ViSi-Genie
doesn’t require any 4DGL coding at all, it is all
done automatically for you. Simply lay the
display out with the objects you want, set the
events to drive them and the code is written
for you automatically. ViSi-Genie provides the
latest rapid development experience from 4D
Systems.
A Serial environment is also provided to
transform the display module into a slave
serial module, allowing the user to control the
display from any host microcontroller or
device with a serial port.
The Workshop 4 IDE is available from the 4D
Systems website. www.4dsystems.com.au
For a comprehensive manual on the Workshop 4
IDE Software along with other documents, refer to
the documentation from the 4D Systems website,
on the Workshop 4 product page.

uLCD-43DT Display Module
Workshop 4 – Designer Environment 10.1.
Choose the Designer environment to write 4DGL
code in its raw form.
The Designer environment provides the user with
a simple yet effective programming environment
where pure 4DGL code can be written, compiled
and downloaded to the uLCD-43D/DT/DCT
Module.
Workshop 4 – ViSi Environment 10.2.
ViSi was designed to make the creation of
graphical displays a more visual experience.
ViSi is a great software tool that allows the user to
see the instant results of their desired graphical
layout. Additionally, there is a selection of inbuilt
dials, gauges and meters that can simply be placed
onto the simulated module display. From here
each object can have its properties edited, and at
the click of a button all relevant 4DGL code
associated with that object is produced in the user
program. The user can then write 4DGL code
around these objects to utilise them in the way
they choose.
Workshop 4 – ViSi Genie Environment 10.3.
ViSi Genie is a breakthrough in the way 4D
Systems’ graphic display modules are
programmed. It is an environment like no other, a
code-less programming environment that provides
the user with a rapid visual experience, enabling a
simple GUI application to be ‘written’ from scratch
in literally seconds.
ViSi Genie does all the background coding, no
4DGL to learn, it does it all for you.
Pick and choose the relevant objects to place on
the display, much like the ViSi Environment yet
without having to write a single line of code. Each
object has parameters which can be set, and
configurable events to animate and drive other
objects or communicate with external devices.
Simply place an object on the screen, position and
size it to suit, set the parameters such as colour,
range, text, and finally select the event you wish
the object to be associated with, it is that simple.
In seconds you can transform a blank display into a
fully animated GUI with moving sliders, animated
press and release buttons, and much more. All
without writing a single line of code!
ViSi Genie provides the user with a feature rich
rapid development environment, second to none.

uLCD-43DT Display Module
Workshop 4 – Serial Environment 10.4.
The Serial environment in the Workshop 4 IDE
provides the user the ability to transform the
uLCD-43D/DT/DCT into a slave serial graphics
controller.
This enables the user to use their favourite
microcontroller or serial device as the Host,
without having to learn 4DGL or program in a
separate IDE. Once the uLCD-43D/DT/DCT is
configured and downloaded to from the Serial
Environment, simple graphic commands can be
sent from the users host microcontroller to display
primitives, images, sound or even video.
Refer to the “Serial Command Set Reference
Manual” from the Workshop 4 product page on
the 4D Systems website for a complete listing of all
the supported serial commands
By default, each module shipped from the 4D
Systems factory will come pre-programmed ready
for use in the Serial mode, unless purchased as a
Starter Kit (SK).
11. Starter Kit
4D Systems highly recommends all first time
buyers of 4D Systems’ displays, to purchase the
Starter Kit when purchasing their first 4D Systems
display solution.
The Starter Kit provides all the hardware that is
required to get the user up and running.
Not all development environments and features
will be needed by every user, however by
purchasing the display solution in a Starter Kit, it
ensures that if you want to take full advantage of
the 4D Systems display solution and try out each
of the 4D Workshop4 Environments, upgrade
PmmC/firmware, you can.
The Designer environment can utilise every
feature of the display, however depending on the
user requirements, a micro-SD (uSD) card may not
be required. The uSD card is used when displaying
images/video/sound, along with datalogging to
uSD, and a programming cable is definitely
required for downloading compiled code and
PmmC/Firmware updates.
The ViSi environment is the same as Designer in
terms of feature utilisation, but is image based so
requires a uSD card, along with a programming
cable.
The ViSi-Genie environment is also image based,
and therefore requires a uSD card and
programming cable also.
The Serial environment does not require either a
uSD or Programming cable to be used, however
can utilise both depending on the user
requirements. The uSD card can be used for such
things as storage of multimedia files and
datalogging, and the Programming cable for
PmmC/Firmware updates, or changing to one of
the other three programming environments.
The Starter Kit includes:
4D Programming Adaptor or Cable
4GB micro-SD Card
5 way cable for easy connection to a
breadboard or host
Display Module
Quick Start Guide
Simply select the Starter Kit option when
purchasing the chosen display module on the 4D
Systems shopping cart, or from your local
distributor.

Note *: Diablo16 has 16 GPIO compared to PICASO’s 13, however PICASO has 2 fixed Serial Ports, and a fixed
I2C port, whereas DIABLO16’s Serial ports and I2C ports are configurable and can be moved to alternative
GPIO. What this means is, if DIABLO16 was to be configured in the same manner as PICASO, in terms of
matching GPIO and communication channels, DIABLO16 would have 1 less GPIO due to 2 of the 16 having to
be configured for the 2nd serial port, and another 2 having to be configured as the I2C, giving 12 GPIO spare for
the User. Of those 12, 2 are only capable of being digital inputs.
Differences in the GPIO – For upgrading from uLCD-43P to uLCD-43D 16.2.
Based on the information in 16.1, it can be seen there are some differences between PICASO and DIABLO16
which affect the complete compatibility of the uLCD-43P based modules, and the uLCD-43D based modules.
If the uLCD-43P was used simply for a single Serial UART and no GPIO, then the uLCD-43D is 100% compatible.
In order to make the uLCD-43D as compatible as possible to the uLCD-43P, the TX1/RX1 UART had to be fixed
to predefined GPIO, however due to the GPIO configuration, they had to be shared.
Due to PICASO uLCD-43P having 2 fixed Serial UART’s, the position on the 30 way header was predefined. Since
DIABLO16 uLCD-43D is capable of having 3 of its Serial UART’s configured to be on a range of GPIO, selected
GPIO were earmarked for the 2nd Serial UART, so it was the same as the PICASO version. This however means
compromises had to be made to the GPIO BUS.
Where the PICASO uLCD-43P module had TX1 and RX1 on the 30 way header, the DIABLO16 uLCD-43D has 0R
resistors to tie BUS0 and BUS1 (PA4 and PA5) to the old TX1 and RX1 positions, to retain compatibility. This
means BUS0 and BUS1 cannot be used if TX1 and RX1 are used. If TX1 and RX1 are not required, the BUS can
be used as per normal.
IO3 of the PICASO uLCD-43P is no longer available, due to the difference in GPIO between the PICASO and
DIABLO16. This is now a N/C (Not connected) pin unfortunately.
Additional signals have been placed on the 30 way header, such as the addition of the 2 input only GPIO’s
(PA14 and PA15) – which can be used as a high speed I2C channel, the addition of the speaker outputs SPK+
and SPK- for attaching an external speaker, and the addition of the AUDIO and AUDENB signals to enable the
use of an external amplifier.
