VMX Encoder

Handles the Encoder ports on the VMX. There are five encoder ports on the VMX.

1. FlexDIO 0,1

2. FlexDIO 2,3

3. FlexDIO 4,5

4. FlexDIO 6,7

5. FlexDIO 8,9 (LabVIEW currently does not use this one)

Encoder

Is a class that contains the code for reading the encoder ports on the VMX. Has only a HG_LIB output.

Read

A vi that allows for reading the encoder count from the port specified by the Create ID vi.

Inputs and Outputs

Name	I/O	Attribute
Encoder in	Input	The input cluster from Create ID
error in (no error)	Input	The error input cluster
Encoder out	Output	The output cluster to go to Delete ID
ENC	Output	The raw encoder count
ENC/dt	Output	The delta change in encoder count
error out	Output	The error output cluster

Reset

A vi that allows for resetting the encoder count from the port specified by the Create ID vi.

Inputs and Outputs

Name	I/O	Attribute
Encoder in	Input	The input cluster from Create ID
error in (no error)	Input	The error input cluster
Encoder out	Output	The output cluster to go to Delete ID
error out	Output	The error output cluster

Encoder Read Example

This example reads the encoder count on Encoder port 0 FlexDIO 0,1.

Encoder Reset Example

This example resets the encoder count on Encoder port 0 FlexDIO 0,1.
