[Emc-users] Questions regarding MESA cards
Just before I dive into knowing these boards deeply (if it is possible without having them) I want to clarify some things: 1. Can several anything I/O MESA cards be used together? 2. How flexible output assignments are? For example, is it possible to run these: 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 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)? 4. Or take 7i43, two 7i39 and run 4 BLDC servos in sine commutation mode? 5. Use MESA cards together with second parallel port for other general I/O, stepgen. 6. Powering 7i39-H. I am planning to use regulated 48V PSU, but.. if I would make unregulated supply, how to select suitable transformer (type, voltage)?

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.
