Re: 3V3 digital signal to the cRIO

I guess I want to take a step back and ask the intent.

Are you simulating digital input to test programing on the cRio, or are you using it to pass information the Pi has already determined to the cRio to take action?

I ask because if you are looking to pass information it may be much easier to use i2c if you don't want to use hub points on the radio, or just pass the data between the two on an ethernet connection (UDP or TCP).

But if you are looking to simulate other sensor data then the other discussions here definitely apply. I would look at the logic level shifters from spark fun. That would be the safe way to do it.
