Windows Interface Driver
For serial Intelligent Interface, Part No. 30402
from fischertechnik Date: 07/27/2000
The driver is in the form of a 32 bit DLL and can therefore be used with all programs and programming languages capable of including or loading DLLs…
kalle is right. Port(Devices) is the node to go for.
unfortunately there is no how to parallel port so far. but on the web you will find plenty of documentation about parallel port interfacing. a few links can be found in HowTo Devices. actually interfacing the parallel port is quite simple. the parallel port has 3 ports:
each 8 Bit; you must read / write to them individually. Port( Devices ) must be given the adress of the port you want to write to. to get this Look up MyComputer -> Hardware -> Device Manager -> select the parallel port -> Properties -> Ressources. there you will find something like
these are the common adresses used for parallel ports.
you have the feed the port-node with a decimal number, so have to translate it from hex.
the parallel port has a data-port, status-port and control-port. see the link below for details or follow the appropiate links here: Electronics Links. consider: some of the pins are for output / some are for input (write / read). carefully design your interface!
and: be sure about the adresses of the ports. writing to the “wrong” port may make your system crash.
Ulrich Müller seems to be a real fanatic on fischertechnik interfaces. Anyway there seem to be different variants made by fischertechnik:
fischertechnik Intelligent Interface Art.-Nr. 30402 is a serial version, documented here. with this pdf it should be very easy to control the interface with the RS232 node
fischertechnik Universal Interface Art.-Nr.30520 is a parallel version. which in principle can be controlled with the Port (Devices) node. I think this a very old interface. This page seems to describe the way to program it. Notice that you probably wont be happy to with the Port node, as you´ll need something like 20 consecutive frames in vvvv to write the necessary impulse sequence to the parallel port. this will obviously take some time.
from a functional standpoint i dont think there is a significant distinction between “universal” and “intelligent” here. if there is any option: choose the intelligent (serial) version.
The Multiface series (Letzte Änderung: 23. März 1998) of interfaces at http://www.knobloch-gmbh.de look quite didactical , but i think they´d suffer from the same issues with the parallel port as the fischertechnik interfaces.
sometimes in the future someone might like to take the delphi headers on Ulrich Müllers page and write a native vvvv node (summer interns apply now) but i´d already promised to write a lego mindstorms node first.
