I think you missed the point of the prior post. The 16th character would normally contain 35 pixels (5*7). It is likely that this display instead maps 21 of those pixels to the 3 7-segment characters. Any normal ascii character you send is going to be a mess in this case. I am guessing three of the 7-pixel columns are mapped to the 3 7-segment characters. You will need to use the controllers 'downloadable' or 'user' character mode to define custom characters to get a meaningful result. Start by defining a custom character with a single pixel on -- this should turn on at most one segment in the 7-segment characters. Now turn off that pixel and turn on the next. Repeat until you've tried each possible pixel, one at a time. You should be able to determine the mapping from pixels in the custom character to segments on the display.
