I recently got LittlevGL working with Teensy 3.5 on the display ILI9341

However, I am having trouble enabling touchscreen can someone please help?

You’re going to have to provide more information.

What steps have you tried? What isn’t working?

Well I need a reference point on how to enable and use touch screen on Ardiuno

You’ll need to have some way of retrieving touch points and finger state (pressed/released).
