TWISTER
PCMCIA-2
The ARMtwister is a small embedded
control board with PCMCIA socket utilizing
the Atmel AT91M40800 Microcontroller.
With its customized version of uClinux-2.4
it is possible to use IEEE 802.11 Wireless
PCMCIA cards, as well as Ethernet cards
and most other 16-bit PCMCIA cards.
Applications
The board is ideal for developing wireless
applications. The onboard flash can be
used for data logging systems. The board
can be used for development as well as for
final products, thereby reducing the effort
for hardware development.
Hardware
The DRAM controller and the PCMCIA host
controller are implemented in a low-cost PLD,
and reduce the cost by saving expensive
SRAM as well as a dedicated PCMCIA host
controller. The PLD design is available as an
optional development kit that makes it easy
to jump-start your own embedded design.
In-System Programming
The ARMtwister supports reprogramming
of the flash by using a standard 20-pin JTAG
header. In addition, PLD firmware upgrades
can be done through JTAG.
Software
The uClinux source distribution includes the
sources for the tool chain, kernel, a large
number of applications and libraries. The web
based configuration makes it easy to select
and customize the modules that are required
by the application. New applications
can easily be added to the build system.
