Configuring the V5 Vision Sensor in VEXcode V5

When starting to program with VEXcode V5, Vision Sensor blocks will not appear in the Toolbox until the Vision Sensor has been configured. 

Adding the Vision Sensor

To configure the Vision Sensor, select the Devices button to open the Devices window.

Select “Add a device.”

Select the Vision Sensor.

Select which port the Vision Sensor is attached to on the VEX V5 Brain. Ports that are already configured for other devices will be unavailable.

  • Once the port has been selected, you will see the Vision Sensor's Configure screen. To Configure, follow the next set of steps.

Configuring the Vision Sensor

Connect the Vision Sensor directly to your computer using a Micro USB Cable before you select Configure on the Configuration screen.

You can use the same Micro USB that you use to connect the Brain to the computer.

Note: The Brain does not need to be connected to the computer or turned on for this process.

Once connected, select the Configure button for the Vision Sensor in VEXcode V5.

Place an object in front of the Vision Sensor, then select the Freeze button.

Select the image on the screen and drag a bounding box around it. Then choose one of the seven signature slots.

  • Be sure to select as little of the background as possible. 
  • In this example, I'm choosing the SIG_1 Slot.

Click to calibrate the color signature.

  • Move the slider until most of the colored object is highlighted and the background and other objects are not highlighted.

Name and save the signature by selecting its label and typing in a name. Here, SIG_1 is being saved as G_CUBE.

If you want to delete one of the saved signatures, select the Clear button in that signature's row.

  • You can also select the Clear All button to delete all saved signatures.

Close to exit the Configuration window after you have saved all of the signatures you want to include. Then select the Done button.

Now your saved signatures will now appear in the Signature drop down in Vision Sensor blocks.

Changing the Vision Sensor’s Port Number

You can change the port number for the Vision Sensor by selecting the Vision Sensor in the Devices window.

Then click on the current port number at the top right side of the Vision Sensor's Configure screen.

Select a different port on the Port Selection screen and the port number will turn green. Then select Done to submit the change.

Renaming the Vision Sensor

You can also rename the Vision Sensor by changing the name in the text box at the top of the Vision Sensor's Configure screen. If you select an invalid name, the text box will highlight red to indicate. Then select Done to submit the device changes to the configuration.

If you already have Vision Sensor blocks in your project, you will need to update the Vision Sensor's name in the Block(s) to the new name using the drop down.

Deleting the Vision Sensor

The Vision Sensor can also be deleted by selecting the “Delete” option at the bottom of the Vision Sensor's Configure screen.

Note: If you delete the Vision Sensor and it is already being used in your project, your project will not work until you also delete the blocks that were using the Vision Sensor.
