Only 1 switch in a group is active at one time; all the others are deactivated. In the case
of a switch in a group, only the down code is applicable. the up code is ignored.

'T': The area from xx1,yy1 to xx2,yy2 is defined as a key
'K': The area from xx1,yy1 to xx2,yy2 is defined as a switch
'U': The actual button is loaded to xx1,yy2 and defined as a key
'J': The actual button is loaded to xx1,yy2 and defined as a switch
'down code':(1-255) return/touchmacro when key pressed.
'up code': (1-255) return/touchmacro when key released.
(down/up code = 0 press/release not reported).
'text': this is a string that is placed in the key with the current touch font.
The first character determines the alignment of the text (C=centered, L=left
justified, R=right justified). Multiline texts are separated with the character '|'
($7C, dec: 124);
optional: after the character '~' ($7E, dec: 126) you can write a 2nd text for a
selected touch key/switch e.g. "LED|on~LED|off"
'nul': ($00) = end of string

Return/touch macro when menu canceled 'mnu Code':(1-255) Return/menu
macro+(item no. 1) after selection of a menu item. (down/up code = 0:
activation/cancellation is not reported.) 'text':= string with the key text and the
menu items. the first character determines the direction in which the menu
opens (R=right, L=left, O=up, U=down). The second character determines
the alignment of the touch key text (C=centered, L=left justified, R=right
justified). The menu items are separated by the character '|' ($7C,dec:124)
(e.g. "uckey|item1|item2|item3". The key text is written with the current touch
font and the menu items are written with the current menu font. The
background of the menu is saved automatically.
Define drawing area
ESC

A drawing area is defined. You can then draw with a line width of n1 and color fg within
the corner coordinates xx1,yy1 and xx2,yy2.
Define free touch area
ESC
A H xx1 yy1 xx2 yy2
A freely usable touch area is defined. Touch actions (down, up and drag) within the
corner coordinates xx1,yy1 and xx2,yy2 are sent.
Set bar by touch
ESC
A B n1 The bargraph with number n1 is defined for input by touch panel.
Set instrument by touch

TOUCH PANEL
The Version EA eDIPTFT70-ATP is shipped with an analogue, resistive touch panel. Up to 100 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. 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.
