Development Kit for Plug-and-Play Touch Screen GUIs
Amulet Technologies supply a complete, self-contained development
kit for the implementation of interactive, touch-screen graphical userinterfaces (GUI) in new or legacy
embedded systems, based on the
company’s ‘Plug-and-Play’ interactive Color GUI IC.
and Amulet’s embedded Graphical Operating System. The Graphical Operating System supports 8-bit
alpha blending with up to 24-bits
of full color, or up to 256 shades
of gray, for photo-realistic graphics and a high-resolution PC-like
appearance. The LCD controller
Amulet’s AGB75LC04 Color GUI
IC is a fully-integrated, stand-alone,
single-chip GUI sub-system that integrates an ARM7 core with a 24bit, 800×600 pixel LCD controller,
resistive touch-screen controller with
4- or 5-wire interface, 160 Kbytes
of SRAM, SDRAM controller, power
management controller, standard
communications interfaces, GPIO
supports up to 800x600 pixel TFT
and STN displays. Communication
interfaces includeIX) High-speed
USB, TWI, UART and SPI.
The Colour GUI IC operates independently of the embedded system,
requiring no MCU-cycles. It can be
deployed in new or legacy embedded systems in a week or less via
a simple UART connection. There
is only a very small amount of
code to be written on the application side in order to implement the
Amulet protocol. Amulet’s royaltyFREE, embedded Graphical-OS
manages all graphics rendering
and servicing of user interaction
with external
input devices
such as touch
buttons, sliders, or touch
screens. Amulet’s GraphicalOS eliminates
the need for
conventional
operating systems such
a s Wi n C E
or Linux that
would typically
be required to run an interactive
GUI.
The STK-480272C GEM development kit consists of a 480×272 TFT
display with integrated touch panel
and a controller board with Amulet’s Color GUI IC with embedded
Graphical-OS, 32 MBit DataFlash
memory for graphics storage and
64 Mbit external SDRAM, Amulet
development tools and sample GUI
source code. The kit also includes
a 5 V DC power supply, stylus,
and USB PC interface cable.
The STK-480272C GEM Development Kit is available now for an
introductory price of $299. The
GEM Compiler and GUI Operat-
ViewPort can be integrated into
any Spin program. It requires one
cog and a single line of code at
the start of your program. It’s easy
to get started with plenty of tutori-
als, videos and documentation.
ViewPort is also configurable and
extensible so you can customize it
to your needs. The Propeller chip
makes it easy to rapidly develop
embedded applications. Its eight
processors (cogs) can operate
simultaneously, either independently or cooperatively, sharing
common resources through a central hub.
Three programming languages
are available: C (via ICC for Propeller), the easy-to-learn high-level
Spin (native), and Propeller Assembly (native), which can execute
at up to 160 MPS (20 MIPS per
cog).
ViewPort is available for purchase
from Parallax or MyDanceBot.com.
Standard version: $59; Ultimate
version: $149 plus shipping.
ing System is included in the kit,
with no licensing fees for production. The AGB75LC04 Colour GUI
IC is available now in 208-PQFP
with 17 GPIO and 225-ball LFBGA
with 39 GPIO.

ViewPort Software V 4.1 for Propeller micro
Parallax is now selling ViewPort
Software (Standard and Ultimate
versions). ViewPort, developed by
Hanno Sander at MyDanceBot.
com, is the premier debugging
environment for Parallax’s 8-cog
multiprocessing Propeller microcontroller. The tool combines an
integrated debugger with powerful graphics that show you what’s
going on within the Propeller.
You can monitor variables over
time with the built in oscilloscope
or change their value while your
Propeller is running. You can also
solve hardware problems with the
logic analyzer at sampling rates
up to 80 Msps, or ad intelligence
to your programs with the fuzzy
logic module or integrate computer
vision using the OpenCV library.
Both Standard and Ultimate versions come equipped with a
debugger. The Standard version
is lowspeed (up to 115 Kbps)
while the Ultimate version is highspeed (up to 2 Mbps) and includes
12
OpenCV (state of the art computer
vision processing), Development
Kit, and Designer (customize the
graphic instrumentation via drag
and drop).
