Re: LabVIEW Encoder not reliably returning Rate

Today we tested the 9 possible resolution combinations of our two encoders, which we'll call Left and Right. When still, the encoder rates both return 0.0; when moving, the non-working one returns NaN (Not a Number). Here are the results:
Y = Yes/returned decimal value
N = No/returned NaN
Format:
LeftResolution, RightResolution: LeftResult, RightResult
4, 4: N, Y
2, 4: Y, N
1, 4: Y, N

4, 2: N, Y
2, 2: Y, N
1, 2: Y, N

4, 1: N, Y
2, 1: Y, N
1, 1: Y, N
