I purchased a 2.4" TFT LCD; and, after lots of attempts and tinkering, finally got it to work with my custom sketch. It was only displaying a full screen of white when using Arduino IDE 1.6; but, when I downgraded to 1.0.5 r2, it worked correctly.
The problem I have now is that the screen does not update all the time. I can monitor serially and see that the code behind the touch is running; but, any updates to the screen do not happen. If I keep selecting, eventually (could be 2 or 10 times) the screen will update.
I know there is nothing wrong with the code or the touch detection since it works intermittently and the code runs resulting from a touch every time. Is there something I may be missing that would cause the screen not to react to code instructions sometimes?
Any help is appreciated.
