5.4 Customize the LCD display
The maximum number of characters per row on the display is 21 (X location with a range 0 to 20).
The size of a character is 8 x 6 pixels.
The maximum number of lines on the display is 8 (Y location). Lines 3 and 6 are separator lines. Lines
7 and 8 are reserved for the annunciators. Two pairs of lines are reserved for the display items with
data, units, annunciators, and plot (optional): lines 1 (Y=0), 2 (Y=1), and 4 (Y=0), 5 (Y=1). For both
pairs, the top line has a Y location of 0. The second line has a Y location of 1. These locations indicate
position relative to the pair, not the entire height of the LCD (Figure 5-4
).
