Question:

When using a 7-inch HDMI capacitive touch screen, the display is normal but there is no touch function

Solution:

  • Check whether the touch cable connector is loose due to transportation.
  • Check whether one end of the USB is connected to any of the 4 USB ports on the Raspberry Pi, and the other end is connected to the USB Touch interface of the LCD screen.
  • You can first connect the USB touch to the USB port of the computer and observe whether it can be recognized by the computer and touched normally, so as to determine whether the touch function is good or bad.
  • Change another USB cable/port
