I'm getting close to finishing a drawing program with the ability to change the color. I accomplished this by using Henning Karlsens "Touch Example: Quickdraw" as a base, then looking at HK's "Touch Example: Buttontest" to learn how to make buttons and highlighting the ring around them. Still has a couple bugs but it's fairly close.
My next goal will be creating a menu with a pen icon to access the drawing program, and maybe a finger icon to access the touch calibration program.
The reason I'm playing around with these programs is to get the basis for programming menu-like functions, buttons and to display data. Then I'll move onto bigger/better things
Oh, and you guys get to see my horrible handwriting
