Probably. The bigger FPGA gives a wider choice of firmwares, there are some functions that won't fit in the smaller one. EMC2 only supports the parallel interface. > 2.

Boards like the 7i33TA make wiring easier (and include the PWM to voltage conversion, if you are not desperate to do that yourself) SPI is a problem. There is an experimental framework that supports the Mesa Buffered SPI interface, but you would need to write a driver in comp for your specific encoders. When I say "experimental" I mean that it isn't even in the development version of EMC2. I can send you a patch file. -- atp "Torque wrenches are for the obedience of fools and the guidance of wise men" ------------------------------------------------------------------------------ All of the data generated in your IT infrastructure is seriously valuable. Why? It contains a definitive record of application performance, security threats, fraudulent activity, and more. Splunk takes this data and makes sense of it. IT sense.
