## What it is
Analog Devices' bare-metal C software framework providing device drivers for ADI components on systems without an operating system. It includes a hardware abstraction layer so the same drivers run across Xilinx, Intel, Maxim, STM32, ADuCM3029, Raspberry Pi Pico, and other platforms.

## Use cases
- drive ADI ADC/DAC chips from a bare-metal microcontroller
- port Analog Devices sensor drivers to STM32 or Pico without an RTOS
- build example projects for ADI evaluation boards on FPGA platforms
- write portable embedded C drivers using a hardware abstraction layer
- get started quickly flashing reference projects to eval boards

## When to choose
- you are using Analog Devices parts on a microcontroller or FPGA with no OS
- you need portable bare-metal C drivers across multiple MCU vendors
- you want ready-to-build reference projects for ADI evaluation boards

## When to avoid
- your target runs Linux or another OS with its own driver stack
- you need drivers for non-Analog Devices hardware
- you want an RTOS-integrated middleware framework

## Facets
- artifact type: library
- maturity: active
- function: embedded, sdk, developer-tools
- domain: embedded-systems, hardware, developer-tools
- platform: embedded, c, cpp, cross-platform
- tags: bare-metal, hardware-abstraction-layer, analog-devices, fpga, microcontroller, no-os, device-driver
