AR1100 RESISTIVE USB AND RS-232 TOUCH SCREEN CONTROLLER
2.0
IMPLEMENTATION – QUICK
START
The AR1100 is designed to be a fully-functioning touch
controller on power-up – no configuration is necessary
and only minimal hardware support is needed to create
a universal controller board (refer to simplified
schematic).
The
hard-coded
defaults
for
the
operational
parameters are suitable for all but the most unique
circumstances. A jumper on the MODE pin easily
selects the sensor type (5-Wire or 4/8-Wire) and the
Communication mode (USB or UART) is automatically
detected and selected by the device. If USB is
detected, the AR1100 automatically defaults to a
HID-MOUSE, compatible with intrinsic drivers of
standard operating systems. Any desired modifications
to either the operating parameters or USB device type
can be easily saved to internal nonvolatile memory to
override the defaults.
