- Hello,
- I'm trying to use a dual-mode isr for data acquisition under
- windows as per Roy Furman's series of articles appearing in Personal
- Engineering and Instrumentation News.
-
- One major component of the technique that I don't grasp is the method
- by which my program can access the data acquired by the isr. Under DOS
- one can use expressions directly involving variables declared in an
- application (typically one of the functions of my data-acq DOS
- applications would be to take care of installing any special isrs).
-
- However, I didn't notice any explanation of how to get data from a
- [buffer maintained by] dual-mode isr. He seemed to assume that it
- would be used in the context of a DOS device driver (a topic about
- which I know little), but I don't want to bother with a device driver
- - I just want to provide the data to my program directly from the isr.
-
- Is there a reliable way to do this? Does anyone have any experience
- regarding Furman's routines, or other approaches?
-
-
- Thanks,
- Mitch
