Hi Donericb,
Hillary is right, typically you don't want to user interface with a real-time target. This includes a monitor (with a desktop like windows/mac) or a mouse. In the case of an LCD, how do you plan to talk to the LCD. If it is thru serial that is very possible. Same goes for a parallel digital protocol. The key is to rememeber that LVRT is made for headless execution of real-time (in-time) processes. In other words, the LCD should be used to report back to the user very simple commands that do not require quick user interface.
Also if it turns out that the LCD is serial, I would look into using VISA commands on the the RT target. I have had good success with those.
