TOUCH PANEL
The Version EA eDIPTFT43-ATP is shipped with an analog, resistive touch panel. Up to 60 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.
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:
1a. Send Command 'ESC A@' or
1b. Touch the touch panel at power-on and keep it depressed.
2. Follow the instructions for adjustment (press the 2 points upper left and lower right ).

Remarks
n1=1..255 border number; n1=0 no border; n2=angle 0=0°; 1=90°; 2=180°; 3=270°
Set the colors (0..32) for monochrome touch buttons (ESC AU AJ).
n=normal; s=selected; f=foreground; b=background
n1=0..255 button number; n2=button angle; n3=X-Zoom 1..8; n4=Y-Zoom 1..8
n1=0: newly defined switches do not belong to a group.
n1=1 to 255: newly defined switches belong to the group with the number n1.
Only 1 switch in a group is active at any 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.
Color for touch labeling. nf=normal fontcolor; sf= fontcolor for selection
Set font with the number n1 for touch key label
n1 = X-zoom factor (1x to 8x); n2 = Y-zoom factor (1x to 8x)
n1=0..15: additional width left/right; n2=0..15: additional height top/bottom
Label output angle: n1=0: 0°; n1=1: 90°; n1=2: 180°; n1=3: 270°
n1=X-offset; n2=Y-offset; n1,n2=0..7 (add +8 for negative direction)
Touch query is deactivated (n1=0) or activated (n1=1)
Automatic inversion when touch key touched: n1=0=OFF; n1=1=ON;
Tone sounds briefly when a touch key is touched: n1=0=OFF; n1=1=ON
Automatic transmission of a new bar graph value by touch input is n1=0: deactivated;
n1=1: is placed in the sendbuffer once at the end of input
n1=2: changes are placed continious in the sendbuffer during input
The touch key with the assigned return code is inverted manually
The status of the switch is changed by means of a command (n1=0=off; n1=1=on)
The status of the switch with the return code (off=0; on=1) is placed in the sendbuffer
down code of the activated switch from the radio group n1 is placed in the sendbuffer
The touch area with the return code (code=0: all touch areas) is removed from the
touch query. n1=0 the area remains visible on the display; n1=1, the area is deleted.
remove the Touch area that includes the coordinates xx1,yy1 from the touch query.
n1=0: area remains visible; n1=1: Delete area

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.
A freely usable touch area is defined. Touch actions (down, up and drag) within
the corner coordinates xx1,yy1 and xx2,yy2 are sent.
The bargraph with number n1 is defined for input by touch panel.

'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
