did somebody get the relay board from conrad (product number: 967720 - LN) to work with vvvv?
shouldn’t it be as easy as that (see attached patch)?
I am using a USB>serial adapter, which might be an issue. but it’s more likely to be a “denkfehler”.
conceptual hints are mostly appreciated.

hihi zepi;
three things:
(1) the XOR node in vvvv doesnt do what you like it to do - the vvvv node XOR will just work with single bits, conrad wants you to xor all 8 bits from the incoming bytes (a so called bitwise xor). So you could use Radix to split the byte into 8 single bits, XOR these, and use another Radix to get everything back into one byte.
Or - and this is much easier - you could use the Expr node, which also features an operation called XOR, which is exactly that type of XOR you´re looking for.
i know both nodes should be able to deal with both definitions…
http://en.wikipedia.org/wiki/XOR tells more about xor.
(2) there are diffent ways for converting numbers into the strings for the RS232 node - each device seem to invent its own style. from the BASIC code provided in the conrad manual i see that they are using the chr$ function. To emulate that, use SpellValue in ascii mode.
and (3)
i dont understand the framedelay before the xor - better remove that…
hei oschatz.
thanks for the support.
working fine now! klick klick klick…
