3.10.5 Set Variables
Variables with a single character can be set directly:
16 15 14 13 12 11 10 9
8
7
6
5
4
3
2
1
Example:
The variable at the fourth digit is to be changed at a display
with 6 variables.
Each digit is implemented by means of a variable (numbers 0 through
5). In order to display a “9” at the fourth digit, ASCII value 39
H
must be
assigned to variable 3 (fourth digit).
Therefore the inputs must be set up as follows:
16 15 14 13 12 11 10 9
8
