Text Scrolling Example
In this example we will see how to display text on the LED matrix of the micro:bit.
To display text on the LED matrix, we will use the procedure
Display of the
procedure Display (Str : String) with Pre => Str'Length <= Scroll_Text_Max_Length;
- Str : The text to be displayed on the LED matrix
Display has a precondition that the length of the text cannot
be more than
Scroll_Text_Max_Length (128 characters).
Here is the code:
with MicroBit.Display; procedure Main is begin loop MicroBit.Display.Display ("Make with Ada! "); end loop; end Main;
