# no-OS
[![Build Status](https://dev.azure.com/AnalogDevices/no-OS/_apis/build/status%2Fanalogdevicesinc.no-OS?branchName=main)](https://dev.azure.com/AnalogDevices/no-OS/_build/latest?definitionId=48&branchName=main)

[Analog Devices Inc.](http://www.analog.com/en/index.html) bare-metal software framework for systems without an operating system.

## What is no-OS?

Most of ADI's products are peripherals to a non-ADI digital engine (FPGA, microprocessor, or microcontroller). While there is major work underway on FPGAs (Xilinx and Intel/Altera) and microprocessors (running an operating system like Linux), the efforts on microcontrollers are fragmented due to the diverse nature of the microcontroller market. no-OS provides reference projects for lower-end processors that can't run Linux or aren't running a specific operating system, helping customers use FPGAs/microcontrollers with ADI parts.

It provides:

* **Platform-agnostic device drivers** for ADI components that run without an operating system.
* **A hardware abstraction layer** so the same driver works across Xilinx, Intel, Maxim, STM32, ADuCM3029, Raspberry Pi Pico and more.
* **Ready-to-build project examples** you can flash to supported evaluation boards to get started quickly.

## Getting started

New to no-OS? Follow these steps:

1. **Clone the repository:**

   ```
   git clone https://github.com/analogdevicesinc/no-OS
   ```

2. **Set up your toolchain and build** by following the [Build Guide](https://developer.analog.com/docs/no-os/build_guide.html) for your platform.

3. **Pick a project** from the [projects list](https://developer.analog.com/docs/no-os/projects_doc.html) that matches your evaluation board, then build and flash it.

4. **Explore the drivers** you need in the [drivers list](https://developer.analog.com/docs/no-os/drivers_doc.html).
