Ok, I think I've got that sorted out. Now to try to cut some rectangular holes in an aluminium box that don't look like they were cut with a cold chisel by a gorilla.It has given me a weird issue though; previously the display worked flawlessly, but now it intermittently won't show line 2. It'll work, then suddenly stop working for a while then mysteriously start again. It shows all the hallmarks of being a hardware issue, except that the demo display programs that come with the display always work without fail. Which makes me think that it has to be something really insidious in my software.
