Alchitry Au FPGA hello world demonstrating use of register interface and JavaFx host application.

Alchitry Au FPGA Register Interface Hello World - JavaFx

This project demonstrates a JavaFx application making use of the register interface to communicate with an Alchitry FPGA Board. It turns on and off LED0 on the Au board. This example also shows how to wire up the USB signals on the Au board to the register interface through the uart components.

It has been tested to work on Windows 10 and should work on OSX with some workarounds.

I walk though this project in detail on Youtube.

Dependencies

• Alchitry Au or Cu
• Java 1.8 or better
• Alchitry Labs Note: Use version 1.2.4. You will also need a design synthisizer appropriate for your board (see the Builders section at the bottom of the Alchitry Labs page).
• Gradle
• An IDE like VS Code if you want to experiment.

Usage

1. Load the fpga/Hello World.alp project into Alchitry Labs.
2. You should be able to load the alchitry.bin file directly from the IDE. Bin file is included. If not, build the project, then load.
3. From the host directory, gradlew run will start the JavaFx application.

You will need to modify the reg.connect statement within HelloWorld.java to match the serial port your OS mapped for the Alchitry board.
