> [!IMPORTANT]

> PicoForge is an independent, community-developed tool and is not affiliated with or endorsed by the official [pico-fido](https://github.com/polhenarejos/pico-fido) project. 

> This software does not share any code with the official closed-source pico-fido application.

>

> Check application [Installation Wiki](https://github.com/librekeys/picoforge/wiki/Installation) for installation guide of the PicoForge app on your system.

>

> PicoForge only supports v7.2 of the PICO FIDO series of firmwares. Support to v7.4 and above

## About



PicoForge is a modern desktop application for configuring and managing Pico FIDO security keys. Built with Rust and GPUI, it provides an intuitive interface for:



- Reading device information and firmware details

- Configuring USB VID/PID and product names

- Adjusting LED settings (GPIO, brightness, driver)

- Managing security features (secure boot, firmware locking) (WIP)

- Real-time system logging and diagnostics

- Support for multiple hardware variants and vendors



> **BETA Status**: This application is currently under active development and in beta stage. Users should expect bugs and are encouraged to report them. The app has been tested on Linux and Windows 10 with the official Raspberry Pi Pico2 & ESP32-S3 and, currently supports Pico FIDO firmware version 7.2 only.

Check the official [PicoForge Wiki](https://github.com/librekeys/picoforge/wiki/Installation) for installation info of the application.



## Usage



1. Connect your smart card reader

2. Insert your Pico FIDO device

3. Launch PicoForge

4. Click **Refresh** button at top right corner to detect your key

5. Navigate through the sidebar to configure settings:

   - **Home** - Device overview and quick actions

   - **Configuration** - USB settings, LED options

   - **Security** - Secure boot management (experimental)

   - **Logs** - Real-time event monitoring

   - **About** - Application information



## Requirements



### Development Requirements



To contribute to PicoForge, you'll need:



- **[Rust](https://www.rust-lang.org/)** - System programming language (1.80+)

- **PC/SC Middleware**:

  - Linux: `pcscd` (usually pre-installed)

  - macOS: Built-in

  - Windows: Built-in



## Building from Source



### 1. Clone the Repository



```bash

git clone https://github.com/librekeys/picoforge.git

cd picoforge

```



### 2. Build and Run



To run the application in development mode:



```bash

cargo run

```



To build for production:



```bash

cargo build --release

```



The compiled binary will be available in `target/release/picoforge` (Linux/macOS) or `target/release/picoforge.exe` (Windows).



## Building and Development with Nix



[Nix](https://nixos.org/) provides developers with a complete and consistent development environment.



You can use Nix to build and develop picoforge painlessly.



### 1. Install Nix



Follow the [Installation Guide](https://nixos.org/download/#download-nix) and [NixOS Wiki](https://wiki.nixos.org/wiki/Flakes#Setup) to install Nix and enable Flakes.



### 2. Build & Run



#### a. with Flakes



You can build and run PicoForge with a single command:



```bash

nix run github:librekeys/picoforge

```



Or simply build it and link to the current directory:



```bash

nix build github:librekeys/picoforge

```



> [!TIP]

> You can use our binary cache to save build time by allowing Nix to set extra-substitutes.



#### b. without Flakes



Download the package definition:



```bash

curl -LO https://raw.githubusercontent.com/librekeys/picoforge/main/package.nix

```



Run the following command in the directory containing `package.nix`:



```bash

nix-build -E 'with import  {}; callPackage ./package.nix { }'

```



The compiled binary will be available at: `result/bin/picoforge`



### 3. Develop



You can enter a developement environement with all the required dependencies.



#### a. with Flakes



```bash

nix develop github:librekeys/picoforge

```



#### b. without Flakes



You can use the `shell.nix` file that is at the root of the repository by running:



```bash

nix-shell

```



Then you can build from source and run the application with:



```bash

cargo run

```
