Encoder problems

[Pausert]

Today I was working on the KOP optical encoders and under no circumstances could I get them to work. I placed the Open encoder and the Set encoder function outside the teleop loop and the Get encoder function in the execute case. This setup worked for my other sensors and I know the encoder works. What am I missing? See code attached.

You should put the initialize parts of the sensor code in the init loop. Also I would try putting the configtimerm.vi before the start.vi. also try looking at the error statements to see what that gets you.

You should under no circumstances create create constants for "DevRef" inputs. You need to open the digital inputs and pass those references into the "ToDigitalSource.vi" (on the encoder pallete) and pass the reference from that into the encoder open. Look at the Encoder Example for... well... an example.

Have you tried the Encoder Example? In LabVIEW choose View>>Getting Started Window, then click Examples and pick Encoder Example from the list. It also shows the wiring, so you can make sure that matches as well.
