Stealthy Lib

Stealthy Lib is a library created, mantained, and used by Cedarcrest High School's FIRST Team, which includes:

• FIRST Robotics Competition Team 4089 - Stealth Robotics
  • Team Website
  • 4089 @ The Blue Alliance
  • 4089 @ FIRST Inspires
• FIRST Tech Challenge Team 7759 - Autonomous Prime
• FIRST Tech Challenge Team 7760 - Mishap
• FIRST Tech Challenge Team 13648 - Jankbot
• FIRST Tech Challenge Team 22152 - Smelt
• FIRST Tech Challenge Team 22153 - Xero

This library includes code that is consistently reused throughout multiple seasons, across multiple teams, and that tends to be useful for FTC and FRC codebases.

---

Structure

This library is structured as a Gradle project, with the following modules:

• core: The core module that contains league agnostic code.
• ftc: The FTC-specific module, which contains code that is useful for FTC codebases.
• frc: The FRC-specific module, which contains code that is useful for FRC codebases.

Please make sure you are using the correct modules for your codebase.

Installation

• FTC Installation
• FRC Installation

FTC Installation

1. Open your FTC SDK project in Android Studio.

2. Open build.common.gradle file of your project.

3. Scroll to the bottom where you should find a dependencies block. Here add the following to the dependencies block:

   maven { url 'https://jitpack.io' }

4. Open the build.gradle file of your TeamCode module (This is the build.gradle in the TeamCode folder.

5. Go to the bottom of the file, and add the following to the dependencies block.

   implementation 'com.github.Stealth-Robotics.StealthyLib:core:v0.1.0-beta' // core lib
   implementation 'com.github.Stealth-Robotics.StealthyLib:ftc:v0.1.0-beta' // ftc lib

   Add the line under already existing dependencies if the dependencies block already exists. If it doesn't exist, you can create one similar to what is shown below. It should look something like this:

   dependencies {
     implementation '...' // example of an already existing dependencies
   
     implementation 'com.github.Stealth-Robotics.StealthyLib:core:v0.1.0-beta' // core lib
     implementation 'com.github.Stealth-Robotics.StealthyLib:ftc:v0.1.0-beta' // ftc lib
   }

6. In build.common.gradle, change the minSdkVersion from 23 to 24:

   defaultConfig {
     applicationId 'com.qualcomm.ftcrobotcontroller'
    	minSdkVersion 24
    	targetSdkVersion 28
   }

7. Ensure your Java version is set to 8. This should already be the case with the latest SDK. If not, you will need to change your Java version. Scroll down in build.common.gradle until you find the compileOptions block.

   compileOptions {
       sourceCompatibility JavaVersion.VERSION_1_7
       targetCompatibility JavaVersion.VERSION_1_7
   }

   Change the 7 to an 8 like so:

   compileOptions {
       sourceCompatibility JavaVersion.VERSION_1_8
       targetCompatibility JavaVersion.VERSION_1_8
   }

8. Perform a Gradle sync your project. You should now be able to use the library in your project files (inside TeamCode)!

NOTE: If your module has a few dependencies, you might have an error related to multidex on building the project. This is caused by the project exceeding the limit for imports enforced by Android Studio. To solve this, add multiDexEnabled true to the below location inside the build.common.gradle file.

defaultConfig {
    applicationId 'com.qualcomm.ftcrobotcontroller'
    minSdkVersion 24
    targetSdkVersion 28
    
    multiDexEnabled true
}

FRC Installation

Open your FRC project in VSCode, and follow the instructions below.

1. Install The Following Vendor Libraries (WPILib Plugin → Manage Vendor Libraries → Install New Libraries (Online))

   • CTRE Phoenix (Phoenix 5 & Phoenix 6
     • https://maven.ctr-electronics.com/release/com/ctre/phoenix/Phoenix5-frc2024-beta-latest.json
     • https://maven.ctr-electronics.com/release/com/ctre/phoenix6/latest/Phoenix6-frc2024-beta-latest.json
   • REV Robotics
     • https://software-metadata.revrobotics.com/REVLib-2023.json
   • PathPlanner
     • https://3015rangerrobotics.github.io/pathplannerlib/PathplannerLib.json

2. Open the build.gradle file of your project.

3. After the plugins block, add the following:

   repositories {
       maven { url 'https://jitpack.io' }
   }

4. Add the following to the dependencies block in the build.gradle file.

   implementation 'com.github.Stealth-Robotics.StealthyLib:core:v0.1.0-beta' // core lib
   implementation 'com.github.Stealth-Robotics.StealthyLib:frc:v0.1.0-beta' // frc lib

   Add the line under already existing dependencies if the dependencies block already exists. If it doesn't exist, you can create one similar to what is shown below. It should look something like this:

   dependencies {
     implementation '...' // example of an already existing dependencies
   
     implementation 'com.github.Stealth-Robotics.StealthyLib:core:v0.1.0-beta' // core lib
     implementation 'com.github.Stealth-Robotics.StealthyLib:frc:v0.1.0-beta' // frc lib
   }

5. Build your project through the WPILib plugin (WPILib Plugin → Build Robot Code). You should now be able to use the library in your project files!
