FlintExample

This repository contains example Java programs designed to run on FlintJVM.
It also demonstrates how to build, flash, and debug Java applications on ESP32 using the FlintJVMDebug VS Code extension. These projects can run well on ESP32.

Prerequisites

Before you start, make sure you have installed:

• Flash FlintESPJVM firmware to your ESP32 board. You can use ESP Web Tool to support flash
• Use vscode and install FlintJVM Debug extension.
• Make sure you have javac (java compiler) installed and can call it in terminal window. You can also run the command javac --version to check.

How to run example:

• Open an example you want to run in vscode. For example, open the FlintExample/examples/FlintIO/Pin folder.
• Update the port parameter in the launch.json file to match the actual port connected to your board.
• To compile the project, click Terminal > Run Build Task... or press Ctrl + Shift + B. After successful compilation, bin/Main.class file will be created.
• Click Run > Start Debugging or press F5 to run and debug the project.

You can also open the entire project as Multi-root Workspaces by opening the FlintExample.code-workspace file.
