Re: Mindstorms, Vex and VexIQ - which?
Just wanted to chime in on this point:
It's hard to tell by looking at it, but the NXT and IQ cables are very similar with one difference; the clips are on opposite sides (right/left) of the cable and the two are not cross-compatible. Also, I do not know what the specific pinouts of the two cables are and if they are compatible at all; I wouldn't recommend mixing the two just to be safe (at least, not for now).
I believe function pointers are on "the list" for our dev team, but it is one of those things that's generally only used by a small (but important!) part of the ROBOTC user base, and may be taking a backseat to more critical issues at the moment. I'll look into it once we get back from break and see if I determine the status of its development.
