Installing the Toolchain

To use Pico de Gallo from a host PC, you need the gallo command-line tool. That’s it — gallo will speak to the firmware over USB and you don’t need any extra drivers on most platforms.

There are two ways to get it: pre-built binaries (fastest), or building from source.

Option A — Pre-built Binaries

Pre-built binaries are attached to every application-v* release on the Releases page. Supported triples:

Download the right archive for your system, unzip, and put gallo (or gallo.exe) somewhere on your PATH.

$ gallo --version
gallo 0.8.0

Option B — Build from Source

If your platform isn’t in the table above, or you want to live on main:

1. Install Rust (stable toolchain, 1.90 or newer — the workspace pins MSRV to 1.90).
2. Clone the repo:

   $ git clone https://github.com/OpenDevicePartnership/pico-de-gallo
   $ cd pico-de-gallo/crates
   

3. Build the CLI:

   $ cargo build --release -p gallo
   

4. The binary lives at target/release/gallo (or gallo.exe on Windows). Move or symlink it into a directory on your PATH.

Tip

On Linux you may want to install the libudev headers first so nusb builds without extra steps:

$ sudo apt install libudev-dev pkg-config

Optional Extras

You only need these if you’re working on Pico de Gallo, not just with it:

• The mdBook source for this book lives under book/. Build with mdbook build book.
• The C FFI library (pico-de-gallo-ffi) builds a .so / .dylib / .dll shared library plus a generated pico_de_gallo.h header. See crates/ffi.md.
• The Python bindings (pyco-de-gallo) build with maturin:

  $ pip install maturin
  $ cd crates/pyco-de-gallo
  $ maturin develop --release
  

  See crates/python.md.

Now verify your device is talking to the host.
