How to use these pins as digital outputs (Pin 4, 5, 6)
The DISCO-B4 device supports three IOs which can be used either as input or
output. These outputs are open collectors. They can be directly connected via
resistors (R) to LEDs, Relays etc., which need no more than
100 mA @ up to + 32.0 V DC
.
The figures below show the schematic of possible output connections. To use and
activate these outputs use the command
$PFAL,IO4
[5,6]
.Set=high
[low,hpulse,lpulse,
cyclic]
for
IO1, IO2
and
IO3
respectively or you can configure one or more alarms that
activate these outputs when specific events occur (e.g.
PFAL,Cnf.Set,AL0=IO.e8=redge:
IO4.Set=cyclic,1000,2000
).
In order to evaluate this alarm, first send this configuration to the DISCO-B4 device and
then trigger IGN-pin to High – as result the IO1 goes High for 1 sec and Low for 2 sec. To
set IO1 to Low, just execute the command
PFAL,IO4.Set=Low.
For more details how to
activate an output and how to configure an alarm, refer to the manual
“
steppIII_FOX-LT_bolero_lt_PFAL_Configuration_Command_Set.pdf
“. Both figures
below show the schematic
connections of how to use this output.
Please note: do
not apply power directly to an output pin without having a device (e.g. a resistor)
between the output pin and external power.
