Remarks
Input ports
n1=0: Read all input ports as binary value (to sendbuffer)
n1=1..8: Read input port n1
The automatic scan of the input port is n1=0 deactivated, n1=1 activated
The input port is n1=0 is evaluated normal, n1=evaluated inverted
Input port n1=1..8 is assigned by falling edge n2=0 to BitMacro n3=0..255
Input port n1=1..8 is assigned by rising edge n2=1 to BitMacro n3=0..255
Output ports
n1=0: All 8 I/O-Ports are inputs IN1..IN8 (=default after Power-On / Reset)
n1=1..8: n1 I/O-lines will be set to output (beginninge at OUT1 upwards)
n1=0: Set all defined output ports in accordance with n2 (=binary value)
n1=1..8: Reset output port n1 (n2=0); set (n2=1); invert (n2=2)
Port expansion with 74HC4094
Set the outputs of the external 74HC4094 (refer to page 8) from port n1=0..255 to port
n2=0..255; n3=0: low; n3=1: high; n3=2: invert
TOUCH PANEL(ONLY EAeDIP128x-6xxTP)
The -xxxTP versions are shipped with an analog, resistive touch panel. Up to 40 touch
areas (keys, switches, menus, bar graph inputs) can be defined simultaneously. The
fields can be defined with pixel accuracy. The display supports user-friendly
commands (see page 17). When the touch “keys” are touched, they can be
automatically inverted and an external tone can sound (pin 16), indicating they have
been touched. The predefined return code of the “key” is transmitted via the interface,
or an internal touch macro with the number of the return code is started instead (see
page 22, Macro programming).

FRAMES AND KEY SHAPES
A frame type can be set by using the Draw frame or Draw frame box command or by
drawing touch keys. 18 frame types are available (0 = do not draw a frame). The frame
size must be at least 16x16 pixels.
BITMAPS AS KEYS
Apart from the frame types, which are infinitely scalable, it is also possible to use
bitmaps (2 each, for not printed and printed) as touch keys or touch switches. You can
use ELECTRONIC ASSEMBLY LCD-Tools*) to integrate your own buttons as images
(“PICTURE” compiler statement). A button always consists of two monochrome
Windows BMPs of equal size (one bitmap to display the touch key in its normal state
and one for when it is pressed). The active area of the touch key automatically results
from the size of the button bitmaps.
SWITCHES IN GROUPS (RADIO GROUP)
Touch switches (radio buttons) change their status from ON to
OFF or vice versa each time they are touched. Several touch
switches can be included in a group (‘ESC A R nr’ command).
If a touch switch in the group ‘nr’ is switched on, all the other
touch switches in this group are automatically switched off.
Only one switch is ever on.
