gen4-HMI Display Modules

1. Description

The gen4 5.0” Diablo16 Integrated Display Module is
part of the latest gen4 Range of modules Designed and
Manufactured by 4D Systems.

The gen4 series was designed specifically for ease of
integration and use, with careful consideration for
space requirements and functionality.

This specific gen4 module features a 5.0” colour TFT
LCD display, with Resistive Touch (DT), or Capacitive
Touch (DCT). It is powered by the feature-rich 4D
Systems Diablo16 Graphics Processor, which offers an
array of functionality and options for any Designer /
Integrator / User.

The Diablo16 processor features include 16
customisable GPIO, capable of PWM, Serial, I2C, SPI,
Pulse Out, Quadrature Input, and Analog Input.

The 5.0” Diablo16 Integrated Display Module features
a TFT LCD Display, is capable of Touch Detection,
microSD memory Storage, GPIO and Communications,
along with multiple millisecond resolution timers, and
Audio Generation.

The gen4 Range is 100% compatible with the
Workshop4 IDE and its 4 different development
environments, providing the User with a wealth of
options for programming and controlling their system.

Anything designed to run on other 4D Systems display
modules featuring Picaso or Diablo16 Graphic
Processors can be run on this gen4 Integrated Display
Module, with little or no required modifications.
Please contact 4D Systems Support Team for
assistance if migrating from a previous model.

The gen4 Range of Integrated Display Modules
features a 30 pin ZIF socket, designed for a 30 pin FPC
cable, for easy and simple connection to an application
or mother board, or for connecting to accessory
boards for a range of functionality advancements.

The gen4 series of modules has been designed to
minimise the impact of display related circuitry, and
provide a platform suitable for integration into a
product. Application boards can sit flush on the back
of the gen4 if required, as the display related
electronics sit inside the plastic mounting base, leaving
the application board surface clear for User circuitry.

4. Hardware Interface - Pins

This section describes in detail the hardware interface
pins of the device.

4.1. Serial Ports – TTL Level Serial

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 User program
downloads, and configuration PmmC /Driver
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.

4.2. General Purpose I/O

There are 16 general purpose Input/Output (GPIO)
pins available to the user. These provide flexibility of
individual bit operations along with serving
collectively for byte wise operations using the BUS
functions

Please refer to the 'DIABLO16-4DGL-Internal-
Functions.pdf' document for information on how to
set the DIABLO16 pin mappings.

As per the table, not all GPIO can be configured to be
every serial port, or RX/TX.

Serial ports output at the level of TTL 3.3V, however
are 5V tolerant, so can accept communications from
5V devices.

Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information.

PA0-PA3:

General purpose I/O pins, or can serve as Analog Input
pins. Each pin can be individually set for INPUT or
OUTPUT or ANALOG. Power-Up Reset default is all
INPUTS. Digital GPIO can source/sink 10mA. For more
information, the Specifications section.
These pins have a 0 to 3.3V range, and have 12 bit
resolution.
For more information, see Section 4.11 ‘Analog
Inputs’.

PA4-PA11:

General purpose I/O pins. Each pin can be individually
set for INPUT or OUTPUT. Power-Up Reset default is
all INPUTS. When set as Digital Inputs, the pins are 5V
tolerant. Digital GPIO can source/sink 10mA. For more
information, see the Specifications Section.

PA12-PA13:

PA12 and PA13 are reserved for the capacitive touch
controller on the DCT-CLB model. These pins should
not be connected else Touch performance may be
degraded. There are 4.7K pullup resistors on each of
these GPIO. Avoid these pins in normal situations on
this DCT-CLB model. Using these pins on non-touch
(D/D-CLB) and resistive touch (DT) modules is however
OK, or in situations where touch is not required. These
pins are 5V tolerant.

PA14-PA15:

General purpose I/O pins. Each pin can be individually
set for INPUT or OUTPUT. Power-Up Reset default is
all INPUTS. When set as Digital Inputs, the pins are

3.3V tolerant. Digital GPIO can source/sink 10mA.
Under special situations, these pins can be utilised for
a high speed I2C interface. Please refer to table in

section 4.4 and information in section 4.6.

Note: Digital GPIO pins are 5.0V tolerant, except PA14­PA15, which are 3.3V tolerant only. PA0-PA3 are 3.3V
tolerant only. All pins output at 3.3V levels.

4.4. Alternate Pin Function 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 can be configured to be any of the
alternate pin functions. Please refer to the tables.

Please refer to the following tables which illustrate
which pins can be associated alternative functions.

4.3. System Pins

+5V IN (Module Voltage Input)

Module supply voltage input pins. Both of these pins
should be connected to a stable supply voltage in the
range of 4.0 Volts to 5.5 Volts DC. Nominal operating
voltage is 5.0 Volts. Note backlight brightness will be
lower for voltages under 5.0V.

GND (Module Ground)

Device ground pins. At least two pins should be
connected to ground.

RESET (Module Master Reset)

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)

Output dedicated to enable or disable and external
amplifier, where required.

AUDIO (PWM Audio Output)

Output specifically for Audio. This pin is a PWM output
from the DIABLO16 Processor. This pin is a 3.3V level
PWM output to drive an external amplifier with
DIABLO16 generated Audio, via an external filtering
circuit to turn digital PWM into Analog. Note that
AUDENB must be enabled in DIABLO16 for any input
signal to be heard.

The previous table illustrates which of the GPIO can be
used for the four different I/O Support Functions.

Note: Once a pin is allocated to an alternate function,
another pin cannot also be allocated to the same
alternate function.

Please refer to the separate document titled
'DIABLO16-4DGL-Internal-Functions.pdf' for more
information on how to set the alternate pin
configurations.

The Alternate pin functions have been broken up into
a few tables for simplification. There are
communication based functions, and I/O support
based functions.
