Split portC of 82c55 in ni6503?

[MiTu]

Does the nidaq-driver allow you to split portC of 82c55
to be splitted to four input and four output lines as
82c55 do? Card used is ni6503 and I know that by
direct register programming I could do the trick, but
that's difficult in winNT.

Hello;

Unfortunately, NI-DAQ doesn't support that feature. To accomplish that, you will need to use Register level programming.

Thanks Filipe,

Any idea where to get a sample dll-code for that kind of io-programming in NT? Perhaps in NI site?

Or just forget the input? I have a rf-relay matrix
and would like to only have a couple of input bits
to read if there is any power inside the box...
