Hello!
I am trying to communicate my PC with a SPI device (a transceiver) and I need to use an evaluacion board to connect the Transceiver to the PC.
The evaluation board uses the parallel port to connects to PC.
As I want to send data to the transceiver (that uses the SPI protocol) I thought that maybe is possible to make a conversion parallel - SPI.
I don´t have experience with labview but I need to know if something like this could be made.
Can anybody help me?
Thanks a lot,
MarÃa.

Thank you so much for the answer, but I don´t want to add more hardware.
What I´d like to know is if it exists the possibility of make this with Labview...
Thank you!!

Do they have their pricing structure reversed?
Part number with Full LabVIEW Development System is less money????

It's not clear what you are trying to do then. If you want to control the parallel port from LabVIEW, you can do so. Please look at the examples that ship with LabVIEW. Help -> Find Examples, search for "parallel". If you want to implement SPI using the parallel port, then you have to do bit-banging, where you manually change the clock and data lines to generate the required protocol. That's what the Cal-Bay software does. The last time I used it, the VIs were viewable, so you can try to download the software and see the way they do it.
If that is not what you are trying to do, then please explain more clearly what you want to do.

I think that pricing is all messed up. The actual board doesn't cost anywhere near that much. The company I worked for purchased it before I got it here, but it was only about $100. We stopped using it a long time ago, though.

Hi!
I changed my mind and I would like to use some of your devices to connect my ISM transceiver to the PC.
The interfaces I need are:
-An SPI that works as slave (my device is an SPI master, it generates its own clock signal)
-6 GPIO
I saw that you have the USB8451 but it works alwasy as a master, so i think i can not use it...
Thank you so much!!

Re: Calbay
They are the only shop that produced a device driver I did not feel the urge to rewrite.
