ESC
Displays the image saved in the EEPROM with the number n1 (0..255) at position x1,y1.
Example: $1B
ESC
Displays an image at position x1,y1.

$F1 $F0 $FF $F0 $6F $60 $70 $E0 $3F $C0 $0F $00
Loads the adjacent image at position 9,4.
ESC
Sets the link mode n1 for the following graphics
functions: ESC P (Set point), ESC G (Draw straight
line), ESC W (Continue straight line), ESC R R (Draw
rectangle), ESC R N (Draw rounded rectangle), ESC R M
(Fill area with pattern).
Example: $1B
Sets the link mode to inverse.
By way of example, a rectangle is drawn alongside with the link modes set, delete
and inverse on an existing background.
Link mode n1:
1 = set: black pixels irrespective of the previous value (OR)
2 = delete: white pixels irrespective of the previous value
3 = inverse: changes black pixels to white pixels and vice versa (EXOR)
4 = replace: deletes the background and sets black pixels; only area with fill pattern 'pat'
5 = inverse replace: fills the background and sets white pixels; only area with fill pattern 'pat'
ESC
Continues a straight line from the last end or point drawn to x1,y1 taking into account
the set graphics mode 'V'.
Example:
$1B $47
$1B $57
$1B $57
A straight line is drawn from 0,0 to 16,4.It is then continued to 22,27 and to 48,15.
ESC
This command suspends the KIT240 for n1/10 seconds.
Example: $1B
ESC
Reads in the input port (n1=1..8 = IN1..IN8). When n1=0, all the inputs are read in as 8-bit binary values
(MSB:IN8...In1:LSB); see application on page 5. Important: The optocouplers invert the input logic (input open:
1). The command "ESC Y I 1" puts this right (input open: 0).
Example: $1B
18
- 1 byte for the image width in pixels
- 1 byte for the image height in pixels
- Image data: number = ((width+7) / 8) * height bytes.
1 byte stands for 8 horizontal pixels on the screen; 0=white, 1=black;
MSB: left, LSB: right; the image is stored from the top down.
The BMP2BLH.EXE program on the EA DISK240 floppy disk available
as an accessory creates the image data, including the width and height,
from monochrome Windows bitmap graphics (*.BMP).
