cncmachineguy,
Are you looking for ideas/pointers for the PC-side of things, PIC-side of things or both?

Have you looked at Jon Elsons PPMC system? It uses the port in EPP-mode (I think), I don't know if he supplies the source code for the "EMC-driver" but it might be worth looking into.


Steve, EMC2 runs on Linux with a real-time kernal applied (not easy to know if you're not into the "CNC-thing") so anything Windows specific probably won't work in this case.

Also, in EPP mode the handshaking and transfers are done by the hardware itself, I'm not sure but I don't think INPOUT32 allows that type of control, I think it's more a brute force type of direct interface to the port register - but I might be wrong on that point.

/Henrik.
