DIGITL INPUTS AND OUTPUTS
EA KIT129 provides 8 digital in- or outputs (5V
CMOS level, grounded). Definition for each line as an
In- or Output can be done at any time. Connection will
be done via J120 as a 2x5 double row pin header.
8 inputs
Factory-set all lines are set to input (internally pulled-up). However, the inputs will
be queried and evaluated directly via the serial interface ("ESC Y R"). Additionally
to that a voltage of >4V starts an internal port macro (if defined). When the 8 lines
are combined, up to 256 port macros can thus be addressed. Each of these port
macros can change the contents of the screen or switch an output, thus enabling
a wide range of control functions. To create the port macros you need a PC and
the EA DISK240
The automatic port query can be disabled by means of the "ESC Y A 0" command.
Note: The logic circuitry is designed for slow operations; in other words, more than
3 changes per second cannot be easily executed. If an input is left open, it is logical
high (internaly pulled-up via 100 kOhm).
8 outputs
Writing the command "ESC Y M anz" will redefine one or more line as an output. Upper lines will be
outputs and lower lines stay as inputs. Command "ESC Y M 2" for example
defines IO8 and IO7 as output lines and IO1~6 will stay as inputs.
Each (re-defined) line can be controlled individually using the "ESC Y W"
command. A maximum current of 10mA can be switched per line. Please
note that these 10mA are valid for L-level; H-level will drive some hundrets
of µA only. For more power use an external transistor or MOSFET.
DEFAULT SETTINGS
After power-on or a manual reset, the registers shown here are
set to a specific value.
Please note that all the settings can be overwritten by creating
a power-on macro (normal macro no. 0).
