I am controlling a 2 channel relay on my Pi B+ and wanted to connect a touch screen to it too, I bought a screen from ebay (3.5" KeDei version 3) that works as a touch screen but unfortunately takes over the GPIO making it useless for what I need it for, I've seen other screens that connect to HDMI instead but they still need to be connected to the gpio pins for the touchscreen aspect.
Does anyone know of a screen I could use for this purpose? Or a way round it? I saw a blog where a guy messed about with the kernel to free up the pins but this looked over complicated and would probably cause more issues than solve.
I should add the cheapest solution would be best
Hope you can help,
