You can download and install it with the default IDE atįrom the launch screen (or any screen actually) select Tools -> MakerHub -> LINX ->
(Note: The Arduino driver is needed for this step. To see where the installed library is in the palette, select ‘Show in Palettes’Ĭonnect the Arduino to the computer and open LabVIEW If prompted, select to open in Package Manager. The library we will use to interact with the Arduino from LabVIEW is called the LabVIEW Interface for Arduino (now, LINX) which we need to download and install to LabVIEW. We wire 5V and Ground from the Arduino to the two outer pins of the potentiometer and connect the wiper pin to A0. Setupįirst, we wire a potentiometer so that it can act as an Analog Input to the Arduino. The setup presented below can be used to read or write to/from any of the pins on the Arduino (including writing PWM out). The TI Launchpad allows for the input to the driverstation by acting as an extra Joystick but requires a bit of setup and is only an input.īelow is presented a setup that allows for an Arduino to be used for generic I/O on the Driver Station through the LabVIEW Interface for Arduino (now, LINX).įor this tutorial, we will implement reading a potentiometer and displaying it on the Dashboard. Sometimes it was an abort button, other times a potentiometer to select an auto program, and still others we wanted to put LED’s on the Driver Station that would light up to alert the drivers/coach to something (game piece acquired, aligned for shot, etc.) Many of the years that the authors have been involved with FRC, we wanted to collect I/O on the Driver Station. These methods would use both the leftEye and rightEye and close them.FRC LabVIEW Tutorials - Arduino - Dashboard Background.Some example methods would be closeEyes or openEyes since these are things the dog are capable of.Some variables (parts) would be: leftEye, rightEye, nose, leftEar, rightEar.Using a dog head subsystem as an example:.These methods will define what those parts are capable of.These variables will be the parts in the subsystem.When programming subsystems we use variables and methods to tell our subsystem what it has and what it is capable of or should do.The head subsystem has the parts: eyes, ears, and nose.Using a dog as an example: the legs, tail, and head are subsystems.The Drivetrain subsystem could contain motor controllers and encoders both physically and programmatically.Subsystems of a robot can contain parts to control or read data from.If we have a ball intake system, we will both call it Intake or Collector.
Command Based Robots are much like Lego, with very basic pieces you can make something simple like a small house or complicated like an entire Lego city.For our programming tutorial we will be creating a Command based robot.FRC Development Environment Setup FRC Development Environment Setup.WPILib Programming Basics WPILib Programming Basics Table of contents.
