Ive been playing around with the nextion 2.8 display and its nearly perfect, only problem is I need the active input from the resistive screen, unfortunately the nextion does not have an option for this. Ive noticed on the back of the board there are these 5 contacts (3.3v, 3 unmarked and, gnd/j2).
Which is around the same number of contacts for a restive connections, so has anyone tested to see if these where resestive connections? Or how would you guys suggest I test these connections with my arduino? What pins should I connect the 3.3v and gnd to (the board gets power from 5v input and powers the resestive touch so connecting 3.3v to 3.3v pin would seem like this would cause a short)
