# Yet Another Framework Interface

YAFI is another GUI for the Framework Laptop Embedded Controller.
It is written in Python with a GTK4 Adwaita theme, and uses the [`CrOS_EC_Python`](https://github.com/Steve-Tech/CrOS_EC_Python) library to communicate with the EC.

It has support for fan control, temperature monitoring, LED control, and battery limiting.

## Installation

You can download the latest release from the [Releases page](https://github.com/Steve-Tech/YAFI/releases).

There are builds for Flatpak, and PyInstaller for portable execution on Linux or Windows.

YAFI is also available on [Flathub](https://flathub.org/en/apps/au.stevetech.yafi): `flatpak install flathub au.stevetech.yafi`.

### Linux

To allow YAFI to communicate with the EC, you will need to enable user access to the `/dev/cros_ec` device. You can do this by running `echo KERNEL==\"cros_ec\", TAG+=\"uaccess\" | sudo tee /etc/udev/rules.d/60-yafi.rules`, and then reload the rules with `sudo udevadm control --reload-rules && sudo udevadm trigger`.

You can also do this by running `curl -Lfs yafi.stevetech.au/udev.sh | sudo sh` which will run the [`add-udev-rules.sh`](add-udev-rules.sh) script.

### Windows

If your Laptop's BIOS supports Framework's EC driver, there is no need to install any third-party drivers. YAFI should also work without administrator privileges.

Otherwise, YAFI supports the [PawnIO](https://pawnio.eu/) driver, and will be automatically used if installed and there is no Framework driver available. YAFI will need to be run as administrator to communicate with the driver.

Currently the PawnIO driver does not support Framework 13 mainboards with 11th, 12th, or 13th Gen Intel CPUs.

## Building

### Flatpak

Build and install the Flatpak package with `flatpak-builder --install --user build au.stevetech.yafi.json`.

You can also create a flatpak bundle with `flatpak-builder --repo=repo build au.stevetech.yafi.json` and install it with `flatpak install --user repo au.stevetech.yafi.flatpak`.

### Pip

#### System Dependencies

This project requires PyGObject, and the introspection data for GTK4 and Adwaita.
On Debian/Ubuntu, you can install these with:

```bash
sudo apt install python3-gi gir1.2-gtk-4.0 gir1.2-adw-1
```

#### Install

Install the package with `pip install yafi`.

Pipx is also supported.

### Windows

It is possible to run YAFI on Windows using [gvsbuild](https://github.com/wingtk/gvsbuild/) and installing YAFI via pip, but it can be complicated and is therefore not recommended.

## Troubleshooting

### `[Errno 13] Permission denied: '/dev/cros_ec'`

This error occurs when the udev rules are not installed or not working. Make sure you have installed the udev rules as described in the [Linux Installation](#linux) section.

### `Could not auto detect device, check you have the required permissions, or specify manually.`

This error occurs when `/dev/cros_ec` is not found, and the `CrOS_EC_Python` library also cannot talk over LPC.
You can either update your kernel to have a working `cros_ec_dev` driver, or run YAFI as root.

It can also occur if you do not have a CrOS EC, like on non Framework laptops.
