Yes, you can fill all your PCI ports and the parallel port with them if you want. > 7i43-P Anything I/O parallel only - 200K FPGA - 48 I/O > 7i39 Dual 3 phase BLDC motor driver > 7i30-4 4 axis 3A servo motor Hbridge for Anything I/O It would need a special firmware, and you would need to check with Mesa that it will fit into the 200k FPGA. But in principle it could be done. I don't even see a TP…BIT file in the firmwares, but I have run a 7i39 on a 7i43, so know that the firmware is out there somewhere. > 3. 7i43 + 7i39 + 7i30-4, but use only one 3-phase motor driver, only 2 H > bridges and other pins for general I/O (provided that I will connect > everything accordingly)? Yes. But it would require special cabling, which is tricky with ribbon cable. You might find these helpful: http://uk.rs-online.com/web/p/pcb-connector-housings/6812856/ There are a range of sizes, and connect individual wires to the Mesa headers quite nicely. > 4. Or take 7i43, two 7i39 and run 4 BLDC servos in sine commutation mode? Yes, that will work. > 5. Use MESA cards together with second parallel port for other general > I/O, stepgen. Yes, that can be done, though you will have the usual step-rate issues with the software stepgens. -- atp If you can't fix it, you don't own it. http://www.ifixit.com/Manifesto ------------------------------------------------------------------------------ Minimize network downtime and maximize team effectiveness.
