We also include one of our Resistive Touch Screen to USB Mouse Controllers - AR1100 so you
can connect one from your computer (or Pi). The Resistive Touch Screen to USB Mouse
Controller is a board that can handle 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 touch screen shows up as a USB mouse so no special
drivers needed. We've tested it sucessfully on Mac, Windows, and Debian Linux (Raspbian on a
Raspberry Pi). Other Linux distributions may or may not work, but if you're running Linux you're
probably used to that. We also noted it does not work with a Raspberry Pi + Windows 10 IOT
yet.
This version comes in 1024x600 instead of the more expensive 1280x800 display. It's also not
IPS so it's not good for wide-angle visibility.
There's a little wired PCB with little buttons that let you enter a menu system for adjusting
brightness, color and contrast. It tries to auto-detect which input you have and switches to that
one or you can 'select' from the menu which to display.
To demonstrate it, we took some photos with the display connected to a Raspberry Pi, but it will
also work connected to any device with HDMI output.
For use with a Raspberry Pi we suggest editing config.txt to set the HDMI to the native
1024x600 in case it doesn't detect the resolution properly. You can see the suggested config.txt
in the HDMI Uberguide. The easiest way to edit the config.txt is to put the Pi SD card into an
every day computer and edit config.txt with any text editor and save.
For use with a BeagleBone Black running Ubuntu/Debian, we found it works when plugged in,
no configuration required.
A power adapter, Raspberry Pi, wire stand, and wires are NOT included. You will need to
either purchase a 5V USB adapter or you can use one you've already got around the house. We
show the display on a bent wire stand which is not included, but you can pick one up here.
