 Hello Zia,

I have succesfully developed a device support for a cPCI card on an industrial PC running windows XP. I have achieved it using AsynPortDriver class, so as M. Heron said, I strongly recommend you to look at Asyn layer documentation and Mark Rivers examples.

Cheers.

I am willing to write the device support for cPCI 7432 card for EPICS in an industrial PC running windows XP. I have the API functions, header file and dll. I am confused only about choosing the second field for this line

device(bi,VME_IO,devAiCPCI,"cpci")as using VME_IO will need to define the INP field as #Ca Sb (Only Card and Signal Numbers) whereas in the API I will need three fields i.e. card number, port number and line (signal) number.

This is my first time to write a device support so I need the advice from experienced for answers to this question that...... What should I choose the signal type here in second field of that line and how is it mapped to API functions from INP field.

I tried a lot to search answer to this question but it was my weakness that I could not find or understand from available material on web.

With Best Regards
