When starting to program with VEXcode Pro V5, Vision Sensor commands will not appear in the Command Reference until the Vision Sensor has been configured.
Here are the different options when configuring a sensor:
- Adding the Vision Sensor
- Configuring the Vision Sensor (requires a Micro USB Cable)
- Changing the Vision Sensor’s Port Number
- Renaming the Vision Sensor
- Deleting the Vision Sensor
Adding the Vision Sensor
To configure the Vision Sensor, select the Robot Configuration button to open the Robot Configuration window. A project must be open in order to use the Robot Configuration 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 window. To Configure, follow the next set of steps.
Click here for help in mounting and wiring your Vision Sensor.
Configuring the Vision Sensor
Connect the Vision Sensor directly to your computer using a Micro USB Cable before you select Configure on the Robot Configuration window.
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 Pro 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 Vision Utility 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 options of Vision Sensor commands.
Changing the Vision Sensor’s Port Number
You can change the port number for the Vision Sensor by selecting the Vision Sensor in the Robot Configuration window.
Then click on the current port number at the top right side of the Robot Configuration window.
Select a different port on the Port Selection window and the port number will turn blue. 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 Robot Configuration window. 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 commands in your project, you will need to update the Vision Sensor's name in the command to the new name.
Deleting the Vision Sensor
The Vision Sensor can also be deleted by selecting the “Delete” option at the bottom of the Robot Configuration window.
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 commands that were using the Vision Sensor.
