x1 y1 n1
Load image from EEPROM
Displays the image saved in the EEPROM with the number
n1
(0..255) at position
x1,y1
.
Example: $1B
$55 $45 $02
$03
$0E Displays image number 14 from the EEPROM at position 2,3.
ESC

L
x1 y1 data...
Upload image
Displays an image at position
x1,y1
.
data..:
- 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;
LSB: left, MSB: right; the image is stored from the top down.
The BMP2BLH.EXE -m 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).
Example:
$1B $55 $4C $09 $04 $0C $0C
$F0 $00 $FC $03 $FE $07 $6E $07 $FF $0F $FF $0F
$9F $0F $FF $0F $F6 $06 $0E $07 $FC $03 $F0 $00
Loads the adjacent image at position 9,4.
ESC
V
n1
Set graphics mode
Sets the link mode
n1
for the following graphics functions: ESC P (Set point), ESC G (straight line), ESC W
(Continue straight line), ESC R R (rectangle), ESC R N
(rounded rectangle), ESC R M (Fill area with pattern).
Example: $1B
$56 $03
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
5 = inverse replace: fills background and sets white pixels; only area with fill pattern
ESC

Continue straight line
Continues a straight line from the last end or point drawn to
x1,y1
taking into account
the set graphics mode 'V'.

A straight line is drawn from 0,0 to 16,4.It is then continued to 22,27 and to 48,15.
ESC

n1
Wait/pause
This command suspends the EA KIT160 for
n1
/10 seconds.
Example: $1B
$58 $0A
After this command the EA KIT160 waits for a second before the next command is processed.
ESC
Y
R
n1
Read input port
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. The command "ESC Y I 1" puts this right (input open: 0).
Example: $1B
$59 $52 $03
Reads in port IN3. The result is sent via RS232.
