Armadillo-70T Embedded Computer Display Module
The Armadillo-70T is a complete Linux based computer display module with built-in 800x480 resolution TFT LCD display, and features a Resistive Touch display (Armadillo-70T), or non-touch display (Armadillo-70) on special request (please contact our sales department for this).
At the heart of the Armadillo-70T is a Broadcom BCM2835 System-On-Chip (SoC), which combines an ARM1176JZF-S CPU Processor with a VideoCore IV GPU in a single package. The Armadillo-70T features 512MB of RAM, which is shared between the CPU and the GPU.
The Armadillo-70T requires a microSD card loaded with an appropriate image in order to start up, as it features no on board Flash memory itself, and uses the microSD card for booting and persistent storage.
By default, the Armadillo-70T has been developed to utilise the Armadillian Operating System, which is based on Raspbian/Debian and optimised for the BCM2835 SoC.
Armadillian has been built by 4D Systems from source to optimise the features of the Armadillo-70T, yet created to remain compatible with the Raspbian OS.
Raspbian is the operating system primarily used by the Raspberry Pi™ which has a large following and development community. The Armadillo, which uses the same SoC, can utilise a majority of applications written for the Raspberry Pi™.
The Armadillo-70T features 13 GPIO, of which 2 can be used for a single I2C Channel, 5 can be used for a single SPI Channel (with 2 Chip Selects), and 2 can be used for a single Serial UART. There are also 2 PWM channels available for the User, one of which is shared with the Mono Audio output via the on board amplifier and mini speaker.
Each of the GPIO’s feature clamping diodes which protect the GPIO from accidental overvoltage, typically if connected to 5V devices.
The Armadillo features dual on-board USB A Sockets, for connecting to devices such as Keyboards, USB Storage, USB Hubs, Bluetooth etc. It also features on-board WiFi and Ethernet, for internet and network connectivity.
How to use Boot and Kernel Packs
To convert a standard Raspbian image for the Raspberry Pi so it will function on the Armadillo-43T you first have to replace the main boot file. This file is usually called "start.elf" and is in the FAT (DOS) partition of the image. It is possible this file may be called something else (some images use "start_x.elf"). Replace the file with the "start.elf" file from this archive, renaming it if necessary.
This will only allow the system to boot and operate the display. It will not allow the use of the touch screen. For this a different set of kernel drivers are needed. These are available for kernel version 3.18.11+. You will need to manually replace your current kernel with the version above
The kernel archive contains all the kernel modules which need to be extracted from within a running system since they need to go in the main filesystem of the image (the ext4 partition).
The kernel archive also contains the kernel image (boot/kernel.img) which is to be placed in the same partition as the start.elf above, renaming it to the same as the existing image. This should be done last by manually copying the file as above with the SD card connected direct to your computer.
Once all the files have been installed the system should be able to support the touch screen. The drivers still need to be activated before they will operate, however.
These two commands should be added to /etc/rc.local:
chmod 777 /sys/class/i2c-adapter/i2c-0/new_device echo ar1020_i2c 0x4d > /sys/class/i2c-adapter/i2c-0/new_device

Getting Started Manual available as a Download
If you are a first time user and just beginning your development, we strongly recommend purchasing a Starter Kit of this same model as it includes additional items that allow you to get started with your development immediately.
Workshop4 is a comprehensive software IDE for Microsoft Windows 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 Workshop4 IDE.
Workshop4 includes four development environments for the user to choose based on application requirements or even user skill level.
This environment enables the user to write 4DGL code in its natural form to program the display module.
ViSi - Genie
An advanced environment that does not require any 4DGL coding at all. Everything is done automatically for you. Simply lay the display out with the objects you want (similar to ViSi), 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 visual programming experience that 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.
This environment is also provided to transform the display module into a slave serial display module. It allows the user to control the display from any host microcontroller or device with a serial port.
SMART WIDGETS EDITOR
Smart Widgets Editor is a powerful utility which enables the generation of Smart Widgets.
- Users can create complex widgets with up to six layers, including the layer for the base image. The order of the layers can be arranged as desired.
- Each layer can contain one or more images arranged in sequence that can be manipulated in a variety of ways. Image manipulation options include horizontal motion, vertical motion, and angular motion. Additionally, the transparency of a layer can be set.
- Two or more layers can be linked to produce synchronized movements of images. This enables the generation of complex widgets with multiple moving parts. Clockwork feature is also supported. This enables users to quickly generate clock widgets.
- Each layer can have a numeric part which can display numbers in various fonts and formats. Alternatively, the numeric part can be a fixed sequence of text.
- The output frames can be utilized using any of the supported Workshop4 environments
Genie Magic is an extension to ViSi-Genie, which is available in Workshop4 PRO. Genie Magic allows the User to add 4DGL code to various points in the ViSi-Genie backend code, which allows Users to take full advantage of the power of 4DGL, while retaining the speed and convenience of ViSi-Genie and its defined communication protocol.
Genie Magic allows you to enter 4DGL code in the form of Events, Code and Objects, along with various touch related additions too, giving you to the power to achieve advanced GUI's in ViSi-Genie without having to write the full code yourself.
Genie Magic is fully supported by the genieArduino and geniePi libraries, making communication with an Arduino or Raspberry Pi host even more powerful.
When using Genie Magic in combination with the Smart Widget Editor, it is possible to use the Smart Widgets Editor tool and Smart Widgets to create other graphical user interface elements such as:
- Dropdown Menu
- Side Menu
- 'Carousel Slider'
- List Box
- Quarter-Rotary Menu
- Dock Menu
- Fading Slide-To-Unlock Button
- Spectrum With Transparency
- And Many Others
