EXTERNAL KEYBOARD
A keyboard (anything from individual keys to a 8x7 matrix
keyboard, J8) can be connected at the plug-in connection.
The connected keys are debounced by means of software.
Please note that it is only possible to connect an external
keyboard to versions without an integrated touch panel.
Each key is switched between an output and an input. Each
input has a 100kΩ pullup. Up to 6 keys can be connected at
each output.
To find out double-key-strokes all outputs must be
decoupled by a Schottky-Diode (e.g. BAT 43).
Transmitting the keystrokes
At each keystroke, the associated key number (1..56) is
transmitted or an internal Touch Makro (only if defined) will
be started. The release of the key is not transmitted. If the
release of the key is to be transmitted as well, this can be
done by defining touch macro no. 0. The automatic
keyboard scan can be deactivated by means of the command "ESC T A 0". If the handshake line (e.g.
CTS) does not permit transmission, keystrokes can be lost.
The key number can be determined as follows:
Key number = (output -1) * 8 +input
(output: a number between 1 and 7; input: a number between 1 and 8).
TOUCH PANEL
Versions EA KIT160-7CTP and -7LWTP are supplied with an integrated touch panel with 56 fields. The
graphics kit offers convenient commands supporting this touch panel. It is possible, for example, to group
a number of touch fields to form a single large key and then draw and label the key. You can also assign
a record code (1..255) to the key you have defined. If a return code of 0 is assigned, the key is disabled
and has no effect when it is pressed.
When the touch keys are touched, they can be automatically inverted and a
tone can sound, indicating they have been touched. At the same time, the
defined return code of the key is transmitted via the serial interface, or an
internal touch macro with the number of the return code is started.
Example:
Definition of a key from field 11 to 21 with the return code 65=´A´ and the text
"STOP". Note: Before individual keys are defined, all fields should be
disabled by means of "ESC T R".
