Getting touchy performance with your screen's touch screen? Resistive
touch screens are incredibly popular as overlays to TFT and LCD
displays. If you want to connect one to a computer you need something
to handle the analog to digital conversion. Most converters we've
found are not very easy to use, and are 'fixed' - making them
difficult to calibrate. The AR1100 is a nice chip that solves this
problem by acting as a touch->USB converter and also comes with
calibration software. The calibration software is Windows only, but
once you've calibrated you can use the screen on any OS. The AR1100
shows up as a regular Mouse or Digitizer HID device so no drivers are
required and it works on any operating system that supports a USB
This breakout board features the AR1100, which has both USB and UART
interfaces available. 99% of the time, you'll want to use the USB
interface but there is some functionality for getting TTL UART data
out (see the datasheet for details) There is also a red LED that
lights up to indicate when a touch has been detected.
For the screens that have 1mm pitch FPC cables, you can plug the
cable right into the connector. The majority of medium/large
touchscreens have that kind of connector. If you have another kind of
touch screen, the four X/Y contacts are available on 0.1" pitch
breakouts so you can hand-solder or wire them. We set this breakout up
for 4-wire sensing only.
You can pretty much just plug and play to get started, for more
details including calibration software, check out the AR1100 page .
Plug any 1mm-pitch 4-wire resistive touchscreen to the on-board FPC
connector, when you plug into a computer's USB port you should see a
new device and touching the screen will cause the mouse cursor to move
