These days someone might propose a camera and some software, way above my pay grade, just sayin'. There are many ways to get 2D information like screen poking, google but I am afraid you will find many to be budget busters even if they do work well. That wasn't with the MOR121 but an older touch board, maybe the newer one is better. It did not work, certainly not well enough for accurate consistent key pressing, The whole point. A small hole on each pad let a wire so,def to the pad and go to the touch sensor. My test involved using a copper clad board with pads isolated by milling channels between the pads. In Settings, select Update & security, then WindowsUpdate, and then select the Check for updates button. If you’re still having problems, check for updates: Select Start, then select Settings. I would guess that it might not work if you aren't actually touching a conductive pad that is directly wired, that is to say not through a glass or plastic sheet. Windows 10 If your touchscreen isn’t responsive or not working how you would expect, try restarting your PC. My attempts to use other touch pads ina keypad or matrix arrangement have been unsatisfactory.īut you could get one MPR121 and experiment for yourself. You would need a number of those MPR121 boards. Any input for a better method would help, thank you!
