TOUCH PANEL (EA EDIP320X-8LWTP VERSIONS)
The -xxxTP versions are shipped with an analog, resistive touch panel. Up to 80 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 16). 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 19, Macro
programming).
TOUCH PANEL ADJUSTMENT
The touch panel is perfectly adjusted and immediately ready for operation on delivery. As a result of
aging and wear, it may become necessary to readjust the touch panel.
Adjustment procedure:
1. Touch the touch panel at power-on and keep it depressed. After the message “touch adjustment
?” appears, release the touch panel again (or issue the ‘ESC @’ command).
2. Touch the touch panel again within a second for at least a second.
3. Follow the instructions for adjustment (press the 2 points upper left and lower right).
FRAMES AND KEY FORMS
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 GROUPS)
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.
