I’m interfacing this touch screen ( https://www.sparkfun.com/products/8977 ) with arduino uno. I used this tutorial to get things going http://kalshagar.wikispaces.com/Arduino+and+a+Nintendo+DS+touch+screen
All works fine, I can get readings of X and Y position. The problem is that I saw that X and Y position depend on how much pressure I put on the touch screen. So if I hold my finger on the touch screen I get a constant X and Y and when I keep my finger in the same place and just increase the pressure then X and Y coordinates seem to increase even if I don’t move my finger. Pressing harder looks like I’m moving the finger on the touch screen.
Is there a way to know the real coordinates even when the pressure changes ?
Thanks and a nice Christmas.
