Windows 10 IoT Core
« on: October 07, 2018, 12:04:11 PM »
Are any of your touchscreens supported in Windows 10 IoT Core?

I connected a NHD-7.0-HDMI-N-RSXV-RTU to a RPi3 running the newest Core version, the display works great, but no touchscreen.

I got it working by powering the display and RPi up at the same time.

Still have an issue with the touch calibration.  With a mouse I can get to 100% of the screen, but with touch there is a ~1/4" "dead" space along all edges (top, bottom, left and right).  This is a major issue since you can't use any buttons that are located close to the edges or the normal location for scroll controls on the right side.

Is there a way to calibrate the touchscreen?  If not, this display is not suitable for most Windows 10 IoT Core applications.

Hi,

The AR1100 (Resistive Touch Screen Controller IC) shows up like a USB mouse, it works on all operating systems as the computer doesn't know it's a touch screen, it just thinks its a mouse. You can adjust the AR100 to consider itself a Touch Digitizer, supported by many but not all computers.

If you have a Raspberry Pi available you may re-calibrate the touch IC via USB using the following program:

or

If you have a Windows computer you may re-calibrate the touch IC via USB using the following program:

Hope this helps,

I have calibrated my display with a Raspberry Pi using rpi-AR1100 and it still has a ~1/4" area on all sides that can't see any touch.

Using a Win10 computer with the Microchip AR1100 Cal Config, how should the preferences be set?

Number of wires?  4 or 5?
USB Mode?  Mouse

Is the Calibration Inset % the "dead" area that I'm seeing?  Can this be 0 or 1%?

Will these setting be stored in the display?

Unfortunately, its a limitation of this type of touch panel   :(

For the best edge to edge touch performance it is highly recommend to use the Capacitive Touch version (if possible):

The capacitive touch panel displays also provide a better resolution.
Could you also provide a video of where the displays cut off?

I can provide a picture in the next few days of the difference when using a standard mouse and the touch screen with a stylus.

This is with a full screen canvas.  The yellow is with a standard mouse and the blue lines is as far as the touchscreen will work with a stylus.  The dead space is the same with Win 10, Win 10 IoT Core and Linux.
