DESCRIPTION OF VARIOUS GRAPHICS FUNCTIONS
The following pages show detailed descriptions in alphabetical order for each individual function.
Examples are shown as hardcopy in an enlarged window of 50 x 32 pixel once the command has been
executed. Examples show all transfered bytes in Hex code.
A
A character n1 will be displayed on coordinates x1,y1 with preset font 'F' and text
mode 'T' (setzen / löschen / invertieren / replace / invers replace / pattern). Origin is
(0,0) at top left hand corner of display. Datas for coordinates apply also to top left
hand corner of a given character. Note: Font No.1 shows capital letters only.
Example:
Character 'E' is displayed at coordinates 19,2
Preset font: 6x8, width 2x and height 2x
Text mode: Replace and black pattern
B
Up to 8 bargraphs (nr=1..8) can be defined, which may oscillate to L=left, R=right,
O=up or U=down direction. Bargraph full level range coordinates are described from
x1,y1 to x2,y2. Scaling of bargraph is performed by starting zero position aw
(=0..254) and max. ending position (full size) ew (=0..254). Bargraph always is
displayed in inverse-mode using the ptn-pattern type: the background remains
preserved in any case. (Note: executing this command only the bargraph range is
defined but nothing is visible on display).
Example:
Defines bargraph no. 1 which oscillates vertical up to top. At full level its coordinates ranges from 4,2 to 9,30.
Displayed start- and end values represent current values of 4..20 mA. (Hardcopy shows bargraph at its full level
operating at $42 $01 $14)
B
Bargraph number n1 (1..8) will be adjusted to a new value (aw <= value <= ew).
If value > ew, than final value will be displayed. Bargraph must be defined before,
see above example.
Example:
Above defined bargraph no. 1 is set now to value 10.
C
Switches display On (n1=1) or Off (n1=0); all display datas remains preserved and
commands can be executed furthermore.
Example:
Content of display becomes invisible, but remains preserved.
