Recently I got an LCD display in dx.com model WBYJB02 and I’m trying to make it work in my BEAGLEBONE Black.
The site does not provide much information about the display controller, but I managed to find a datasheet.
The information I have about WBTJB02 are the following:
Touch screen Controller: XPT 2046 (ADS 7843) - Datasheet at: http://people.ece.cornell.edu/land/courses/ece4760/FinalProjects/f2012/hs734_ks834/hs734_ks834/XPT2046.pdf

The objective of this experiment is to discover how the LCD works, the TouchScreen and SD card reader.
Any help is welcome
