Can you recomend a PC Card IO controller

Hi all.



I am looking for a PC (pcmcia) card that has both digital and analogue I/O. I need to interface an onboard laptop to a mobile platform with sensor array.



Need something well supported and has documented API's so I can program in C or C++.



OS not that crucial.



Exact requirements not defined yet, but 16 digital I/Os and 4 analogue at



10bit would be minimum.

Thanks up front.


Putting aside our obvious political disagreements. (This elitists will try! lol )

Have you considered using a microcontroller for IO and passing I/O up and down a serial interface? Likely add lag, etc, but might be easier from the C++, simple comm. i/o.

Seems like the oopic-r might work for this. Has built in rs232 so you can use a regular ole' serial cable, tty right out your laptop. just an idea. take it or leave it.

Thanks

Agreed, putting aside the politics. lol

I had considered the use of microcontrollers as an interface, but the bulk of my processing is going to be fourier transforms and jocobian matrices, which are very processor hungry and I don't think I can either implement them on a micro controller or stream the output through from a serial port quick enough. I think you might of pointed me in the right direction tho. I am now looking as DSP (Digital Signal Processors) boards to use inplace of the suggested micro controller. I think I might be able to balance the processor load a bit better with this combo.

Thanks. Mutual Respect Iain

Have you looked at the USB devices such as at

?

Fairly inexpensive with reasonable data rates and probably more portable than PCMCIA/PCCard.

They have PCMCIA stuff as well...

Nice one Rich.

Just the job. Going to purchase a couple of these just as soon as I can work out the export/import tax from USA to UK.

Thanks guys.
