Hello, about a week ago, I wrote: > I need to parse user-supplied strings to comedi addresses (to connect > comedi and MatPLC), but there doesn't appear to be a standard function > for that, or even a convention about how the addresses should look. > Would the following format make sense? ... > device: type subdevice.channel options etc. I've just written the function to parse that format, if anyone wants it; for the time being, it's in the MatPLC CVS, and it can be downloaded at http://www.baum.com.au/~jiri/mat_comedi I'm not sure whether this should be contributed to the comedi library, or whether it should be a MatPLC-only thing. However, I suspect that many others will need to do this kind of thing too, which would speak for including it in comedi itself; and it'd be good if everyone used the same format. > Examples: > I2.3 - digital input, device 0, subdevice 2, channel 3. > 1:X7.3/2_DIFF - converted analog input, device 1, subdevice 7, > channel 3, range 2, reference AREF_DIFF. > U.2 - analog output, device 0, subdevice 0, channel 2, default range > and reference.
