The Gecko 540 manual says it's OK with a 3.3V input signal and it looks like it also provides for four input signals. I'm not sure how protected those input are, but if the signals on the DB25 can be configured to not go over 3.3V, the G540 may be all you need. ...and assuming the G540 is mounted in close proximity to the DE0-Nano, you likely don't need anything fancy in the way of buffers or translation logic. -- Charles Steinkuehler [email protected] -- website: http://www.machinekit.io blog: http://blog.machinekit.io github: https://github.com/machinekit --- You received this message because you are subscribed to the Google Groups "Machinekit" group.
