Figured out display, just need to transmit touch signals wirelessly.

What I have is a 5" monitor with a USB touch overlay connected to my laptop with a USB cable.

I've done quite a bit of research and found solutions only for analog sticks, keyboards and mouse; but none for touch.

What I'm understanding is a micro-controller and a BLE module is needed. Only thing left would be the code.

Since the analog input is already converted to digital and outputs that data via USB what can I do to transmit that data wirelessly?

Also the computer recognizes this device as a USB mouse

  • \$\begingroup\$ "The touch screen shows up as a USB mouse so no special drivers needed." taken directly from the products description: adafruit.com/product/2260 I understand it's an absolute position device and knowing that how can I program an Arduino Mini Pro with a BLE module to relay that data wirelessly? \$\endgroup\$

    \$\begingroup\$ not the first fime marketers have made untrue claims. anyway , you'd need to make the arduino act as a USB host. this is not going to happen unless the touch screen is low speed USB. and then it'd just be really tricky \$\endgroup\$

  • \$\begingroup\$ @Jasen True, though any modern computer would have drivers for both, so no special drivers needed claim still holds. \$\endgroup\$

I think you're looking for a 'wireless USB hub'.

  • Place this at your monitor, plug the monitor touch USB into it.
  • Insert the receiver into your laptop.

If you can't buy a wireless USB hub, here's something you could pretty easily build using a Raspberry Pi or any similar single-board computer running Linux (using something smaller like an Orange Pi Zero would make sense):

  • Connect your touchscreen to RPi's USB port
  • Make sure the RPi connects to your WiFi automatically
  • Start USB/IP daemon on it (install with apt-get install usbip if missing)
  • Install a USB/IP client for your computer (I guess you need one for Windows)
  • Export the touchscreen device and enjoy!
