CONNECTION FOR DOT-MATRIX DISPLAY
You can connect a single external dot-matrix module (with
HD44780 or compatible) with 1x8 up to 4x20 or 2x40
characters at eyelets J6 and J7. This dot-matrix display
can be addressed very conveniently by means of ‘ESC T
xx’ terminal commands. Alternatively, ‘ESC L xx’
commands are available for controlling the HD44780
directly. A potentiometer for contrast adjustment is already
fitted. A suitable series resistor R
backlighting.
MACRO PROGRAMMING
Single or multiple command sequences can be grouped
together in macros and stored in the data flash. You can
then start them by using the Run macro commands. There
are different types of macro:
Normal macros (0..255)
These are started by means of an ‘ESC MN xx’ command via the serial interface or from another
macro. A series of macros occurring one after the other can be called cyclically (movie, hourglass,
multi-page help text). These automatic macros continue to be processed until a command is received
via RS-232 or another macro is activated (e.g. touch, port or matrix macro).
Touch macro (1..255)
Started when you touch/release a touch field (only in versions with a touch panel - TP) or issue an
‘ESC MT xx’ command.
Menu macro (1..255)
Started when you choose a menu item or issue an ‘ESC MM xx’ command.
Bit macro (1..8) or (9..16)
Started when a voltage is applied/changed at individual inputs IN 1..8 (bitwise) or by means of an
‘ESC MB xx’ command. Bit macros 1..8 respond to a rising edge, whereas bit macros 9..16 respond
to a falling edge of inputs 1..8.
Port macro (0..255)
Started when a voltage is applied/changed at the 8 inputs IN 1..8 (binary combined) or by means of
an ‘ESC MP xx’ command.
Matrix macro (0..64)
Matrix macro 1..64: Started when you press a key or issue an ‘ESC MX xx’ command.
Matrix macro 0: Started on release when a key is no longer depressed or by means of a command.
The matrix keyboard is connected at the inputs and outputs; a single 8x8 matrix keyboard can be
connected at most.
Power-on macro
Started after power-on. You can switch off the cursor and define an opening screen, for example.
Reset macro
Started after an external reset or after a voltage drop under 4.7V (VDD-VSS).
Watchdog macro
Started after a fault/error (e.g. failure).
Important: If a continuous loop is programmed in the power-on, reset or watchdog macro, the
display can no longer be addressed. In this case, the only thing you can do is: DIP switch 5
to ON, power-off, power-on and then DIP 5 to OFF. The macros then have to be read in again.
