How to make a button in shuffleboard?

[icg]

How do you make a button on the shuffleboard that lets you do something? For example, can we make a button on the shuffleboard that changes the LEDs connected to the robot to red?

Short answer: Yes.

Long answer: Doing this is kind of verbose/annoying with the standard API. You have to keep the NetworkTableEntry object returned by the shuffleboard add method, and read its value in some periodic function.

If you use Oblog, however, this is as simple as:

@Config.ToggleButton
void enableLEDs(boolean enabled) {
  // Do whatever you want here
}

Hi, thank you for your response. We downloaded Oblog but it’s not working because build.gradle always crashes when loading the dependency. Building doesnt work.

[Oblarg]

Can you post your build.gradle? Also, make sure you’re connected to the internet for your first build after adding the dependency.

You can code-format your post by surrounding it in triple backticks:

You need to remove the <> from the version tag.
