Building

Requirements

You'll need the following to be able to build this:

git
C/C++ compiler (supporting C11 and C++17)
- GCC or MinGW works for this
cmake
Rust 1.59 or greater
Pico SDK

If you're on Linux, use your appropriate package manager, such as apt, dnf, yum, or zypper. Most modern versions of Linux that are supported will install these.

If you're on Windows, please follow the links and use the given installers/scripts from the websites above.

Clone

First, grab the Pico SDK from the link above via git clone. You'll need this when it comes to building.

Clone the repository by running the following (or using your favorite git client):

git clone https://scm.wyattjmiller.com/wymiller/AutoBar/

Make sure that the Pico SDK and the AutoBar repositories are sitting side-by-side. This is needed because you have to set the PICO_SDK_PATH environment variable and the settings require that the repositories need to be set that way. You can do this in Linux by running the following:

export PICO_SDK_PATH=../pico-sdk/

Alternatively, you can run the following in Powershell if you're on Windows:

$Env:PICO_SDK_PATH = "../pico-sdk"

Run the above Powershell command when you're in the AutoBar directory (again, if you're running on Windows).

Installation of requirements

Fedora Linux

First, install a C/C++ compiler and git. Install via dnf:

sudo dnf install gcc gcc-c++ git

Install Rust, rustc and cargo via rustup:

curl --proto '=https' --tlsv1.2 -sSf https://sh.rustup.rs | sh

Windows

First, install MinGW for a C/C++ compiler. Download and follow the installer.

Next, install git. Download and follow the installer.

Finally, install Rust, rustc and cargo via rustup. We assume the Windows installation is running amd64 hardware.

Building (for real this time)

Run the following commands in sequential order in the root of the AutoBar directory:

cargo build --manifest-path libautobar/Cargo.toml --target thumbv6m-none-eabi -r
cmake .
make

The first command invokes the cargo command, which builds the Rust library.

The next command invokes cmake. It's not really a build system per se but it generates a Makefile for us to use make.

Speaking of which, the last command that's invoked is make which links the library and executable together and builds them.

Installing

Press the BOOTSEL button on the RP Pico until you get the RP Pico to show up as a mass storage device on your computer. From there, you can drag the autobar.uf2 from the root of the AutoBar directory to the root of the RP Pico. It should run automatmically once that is done.
