tell me the steps to be followed to scroll the sub-menu options using display start line command. Doesn't Michael explain all that in the post that you cited originally: Michael Karas said: (my emphasis)There are two situations where it is desireable to have the start display line begin a frame from another position in the display memory. One of these is if you want to scroll the display one line at a time. Under these conditions to scroll simply means changing the start page register by one count. The display screen image now rolls one row/column. What used to appear on the first line now shows on the last line (if you have a 64 line matrix on the display). Using this means to scroll the display permits a real time smooth scroll of the display to occur without having to reload the entire display memory with new data at every scroll event.
