I purchased one of these cheap, no name, no part number, boards off ebay. http://www.ebay.com/itm/111793872449?_trksid=p2060353.m2749.l2649&ssPageName=STRK%3AMEBIDX%3AIT, and am using the Adafruit library.
It seemed to work well with a test sketch but when I designed my own layout I found that areas defined to receive clicks on one part of the screen gets clicked randomly and repeatedly. Any control I put in this area was affected but if I moved the control to another part of the screen it worked fine. I also inverted the screen rotation and the problem moved to the other side meaning it must be a hardware issue.
Is this a common problem with touch screens? Is there some code to filter out false clicks that I'm not aware of? I just wanted to be sure before sending it back for replacement. Thanks
