Armadillo-43(T) – Linux based Computer Display Module
The User Button is connected to GPIO46.
To edit which script is executed when the User
Button is pressed, simply run the Armadillo Config
tool, which can be found in the ‘start’ menu of the
Raspbian OS, or can be launched via Terminal by
typing:
sudo armadillo-config
Simply click on the User Option, and select the
Script of your choice.
Startup - X Windows or Terminal 6.8.
It is possible to enable the Armadillo to boot up
into X Windows, or to the Terminal, using the
Armadillo-config tool, which can be found in the
‘start’ menu of the Raspbian OS, or can be
launched via Terminal by typing:
sudo armadillo-config
Simply click on the Startup button, and select Yes
or No as required. Selecting Yes will boot into X
Windows by default, and Selecting No will boot to
the terminal.
Selecting Default X Windows 6.9.
On the 4D Systems Raspbian Image, are two
different X Windows for the User to select.
One is LXDE, which is the ‘normal’ X Windows
found on the Raspbian Operating System. The
other is called ‘Enlightenment’, which is an
experimental environment which is more suited
for touch screen applications, such as the
Armadillo, however has some issues and is still
under development.
The default X Windows can be selected using the
Armadillo Config tool, which can be found in the
‘start’ menu of the Raspbian OS, or can be
launched via Terminal by typing:
sudo armadillo-config
Simply click on the Desktop icon, and then select
either LXDE or Enlightenment, as required.
This can be changed again by going back into the
Armadillo Config tool, and selecting the other one,
as required.
Changing the Resolution / Scale 6.10.
A neat feature which is available on the Armadillo,
is the ability for the display output to be scaled to
enable larger windows to display fully, since the
4.3” display can be on the small side when dealing
with some of the default windows found in the X
Windows environment.
Using the Armadillo Config tool, which can be
found in the ‘start’ menu of the Raspbian OS, or
can be launched via Terminal by typing:
sudo armadillo-config
Selecting the ‘Screen Resolution’ icon, will take
you to a page which enables you to change from
the default 480x272 resolution, up to much larger
resolutions. Note however, the actual resolution of
the display is fixed, this cannot be changed, but
the scaling that is output from the frame buffer
can be modified which makes the resolution of the
display appear to change. The limitation of this
however is the larger resolution you select, the
harder things are to read and make out of the
screen, since there are only so many pixels on the
actual display.
