Very new to this RPi thing but due to wanting to fit it into a case I printed I bought this touchscreen for my pi from ebay http://www.ebay.com.au/itm/201426004372 ... EBIDX%3AIT.
When I power it up with the pi it lights the screen with coloured stripes. Do I need to give it its own power source as well? I am using the HDMI cable from RPi2 to the screen. Do I have to add some code or a driver to it and if so how? The RPi works great on the 19" monitor but its too bulky to carry around and I want to do some things away from the home. I could use my tablet but that defeats the advantage of having a RPi.
