DESCRIPTIONS OF THE VARIOUS GRAPHICS FUNCTIONS
On the following pages you will find detailed descriptions of all of 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 is executed. The bytes to be transferred are
shown as hex values in the examples.
ESC
Up to 2 bar graphs (no=1..2) 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 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:
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..2) 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:
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 (L - white), inverted (I) or filled (S - black).
Example:
Inverts the entire contents of the display.
ESC
Switches the contents of the display off (A - not visible) or on (E - visible). Outputs are still possible when it is
switched off.
Example:
The contents of the display are no longer visible after this command.
Note: This does not mean that power supply current is reduced.
