DESCRIPTIONS OF THE VARIOUS GRAPHICS FUNCTIONS
On the following pages you will find detailed descriptions of all the functions in alphabetical order. In
each case, an enlarged section of the image, 50x32 pixels in size, is shown as a hard copy example,
indicating the contents of the display after the command has been executed. The bytes to be
transferred are shown as hex values in the examples.
ESC
Up to 4 bar graphs (no=1..4) can be defined. These can extend to the left (L), right
(R), up (O) or down (U). At its full extent, the bar graph occupies an area from
coordinate x1,y1 to x2,y2. It is scaled with the start value (no extension), sv
(=0..254), and the end value (full extension), ev (=0..254). The bar graph is always
drawn in inverse mode with the pattern (pat): The background is thus always retained.
(Note: When this command is executed, it defines the bar graph but does not display
it.)
Example:
$1B $42
Bar graph no. 1, which extends upwards, is defined. When it is fully extended, it takes up an area from 4,2 to
9,30. The start and end values correspond to a 4..20 mA display. (The diagram shows the bar graph fully
extended, as represented with $42 $01 $14.)
ESC
The bar graph with the number n1 (1..4) is set to the new value (sv <= value <= ev). If
value > ev, the end value (ev) is displayed. The bar graph must be defined first (see
above).
Example:
$1B $42
Bar graph no. 1 defined in the above example is set to a value of 10.
ESC
The entire contents of the display are deleted (white).
Example:
ESC
The entire contents of the display are inverted.
Example:
ESC
The entire contents of the display are filled (black).
Example:
ESC
The contents of the display are switched off (made invisible). Outputs are also possible when the contents of the
display are switched off.
Example:
After this command is executed, the contents of the display are no longer visible.
ESC
The contents of the display are switched on (made visible).
Example:
After this command is executed, the contents of the display become visible again.
