Touch screen co-ordinate display
Posted: Sat Jun 22, 2013 9:24 pm
I have been using a touch screen, the same one used with the EB076. The screens I have built up I have done so by using Microsoft Word. I have detailed how I have done this towards the end of this post http://www.matrixmultimedia.com/mmforum ... 46&t=12147.
I have found with the display that the touch screen co-ordinates, especially on the y axis do not match up exactly with the pixel co-ordinates. I have made a simple bit of code that when each time the screen is pressed the x and y axis co-ordinates are displayed on the screen until the next time the screen is pressed, the next lot of results are displayed. I have found this quite useful especially after creating a screen, you can load that screen using the simple program and then collect the required touch co-ordinates off the display that you are interested in, to include in your code.
I hope this is of some help.
