a121-sys is a Rust crate offering raw bindings for interfacing with the Acconeer A121 V-Band radar sensor. Designed for embedded systems, it provides low-level access to the sensor's functionalities, enabling the development of high-level abstractions in a no_std environment.

This crate is intended to serve as a foundation for accessing the detailed capabilities of the A121 radar sensor, including advanced configuration and sensor management.

The a121-sys crate exposes raw bindings necessary for implementing the following features:

• Distance Measurement: Direct access to configure the radar for precise distance measurements.
• Presence Detection: Direct access for detecting the presence of objects or individuals within a specific zone.

These features are made available through the crate's feature flags, allowing users to include only what they need for their application.

• Acconeer A121 Static Library must be accessible in your build environment.
• arm-none-eabi-gcc is required for building the C wrapper for some examples.

# Ubuntu
sudo apt-get install gcc-arm-none-eabi

ESP targets require ESP toolchains, installable via espup (https://github.com/esp-rs/espup).

Support is dependent on the Acconeer A121 Static Library's availability:

• arm-none-eabihf (gcc, armcc, armclang)
• esp xtensa and riscv

To use a121-sys in your project, add it to your Cargo.toml:

[dependencies]
a121-sys = "0.2"

Ensure all dependencies are correctly set up in your build environment.
