Pathweaver Characterization Issues

Technical Programming
1

Our team, FRC 4087 Falcon Robotics, is attempting to use path planning for the first time this season. We have been able to test on our practice drivetrain, driven with Talon SRX’s, but were concerned that there is no SparkMAX option on the characterization setup. We were wondering whether or not the Spark configuration of the characterization would work for our SparkMAX drivetrain (4 SparkMAX’s driving 4 Neo’s), or if there is another way to proceed.

An additional question we had: when we initially tried to characterize the robot with the TalonSRX’s, we tried having our encoders connect to the TalonSRX encoder port (TalonSRX’s set up with CAN). However, when we tried to import the information necessary to read the values from the TalonSRX’s (getSelectedFeedbackSensor() with quadrature encoders selected). We tried to also just copy the Phoenix json into the program but to no success. Any ideas what we did wrong?

Are you using an early version of the characterization program? The current version has two SparkMax project types. https://docs.wpilib.org/en/latest/docs/software/wpilib-tools/robot-characterization/generating-project.html#select-project-type

What went wrong? This worked fine for us. Did you use the Talon Project Type? Are you aware there’s a Project Type selector on the top right of the tool with both Talon and SparkMax options?

Not sure how we missed that! That’ll do it, thank you.
And we figured out the issue - just an outdated gradle.build.

We weren’t running an old version, we just didn’t see the project types option for some reason. That answers our question, thank you!
