Study Notes
- Setting up a configuration is essential for programming a robot.
- It involves informing the Control Hub about the connected sensors, motors, servos, and other devices.
- Configuration is a crucial initial step before programming.
Importance of Configuration
- Although REV Control Hubs are identical, robot configurations differ.
- The use of motor, servo, and digital ports varies from robot to robot.
- For instance, a Color Sensor V3 might use I2C Bus 1 on one hub, while a distance sensor uses the same bus on another.
- The Control Hub doesn't inherently know how to transfer information from attached devices for use in an OpMode.
- Hardware mapping is a two-step process.
- The hardware mapping requires creating a configuration file using the Driver Hub.
- The hardware mapping then involves calling the hardware map within an OpMode.
- In OnBot Java, programmers must create variables and assign external hardware units.
Accessing the Configuration Utility
- Open the Driver Station app menu and select "Configure Robot".
- In the Available configurations page, select "New".
- In the USB Devices in configuration page, select "Control Hub Portal."
- If an Expansion Hub is connected, it will appear as an Expansion Hub Portal.
- Pressing "Scan" on an existing configuration may erase named devices; a new file is needed for camera/Expansion Hub additions.
- Within the Hub Portal, select the device to configure, typically the Control Hub.
- If an Expansion Hub is connected to a Control Hub, the Expansion Hub will also appear as a configurable device in the portal.
Configuring Hardware
- Digital and analog devices are configured differently than I2C devices.
- Each physical I2C port represents a different bus that can support multiple sensors.
Configuring a Motor
- Select "Motors."
- The Motor page allows configuring all four motor ports on the Hub.
- On Port 0, open the drop-down menu and select the appropriate motor type, such as "REV Robotics Core Hex Motor."
- Configure the motor ports in the configuration file to match the actual motor types used.
- Name the motor (e.g., "test_motor") and select "done."
- Remember that the REV Control System is case sensitive when naming hardware in the configuration file.
Saving the Configuration File
- After configuring the motor, hit "Done" twice, then hit save on USB Devices in the configuration page.
- Name the configuration (e.g., "helloRobotTest") and select "Ok."
- The FTC SDK doesn't enforce a specific naming convention.
- Nonetheless, it's common to use lowerCamelCase for naming configurations
- After saving, press the back arrow to activate the configuration.
- The Robot Controller will restart.
