Software engineers: It's time to get promoted. Starting NOW! Subscribe to my mailing list and I will equip you with tools, tips and actionable advice to grow in your career.
This repository contains Ada source code and complete sample GNAT projects for selected bare-board platforms supported by GNAT. Initially the repository contains software for ARM platforms from a specific vendor, but we intend this to be a location for both AdaCore and the community in general to contribute support for additional processors, platforms, and vendors.
To start using the Ada_Drivers_Library, please go to the examples directory where you will find instructions to run your first project.

The software is written in Ada 2012 and uses, for example, preconditions, postconditions, and the high-level iterator form of for-loops.
In addition, a GNAT implementation-defined pragma is used extensively. This
pragma makes it possible to avoid explicit temporary copies when assigning
components of types representing hardware registers requiring full word or full
half-word accesses. The pragma is named
Volatile_Full_Access. Those persons
wishing to submit additions to the library should see the GNAT Reference Manual
Therefore, building with the sources requires a compiler supporting both Ada
2012 and the GNAT-defined pragma
GNAT GPL 2017
compiler for ARM ELF is one such compiler (Download it
here). A recent GNAT Pro
compiler for that target will also suffice.
Initial provision is for the hardware in the STM32F4 family of 32-bit MCUs, as
defined in the
RM0090 Reference Manual (Doc ID 018909 Rev 6, Feb 2014) by
STMicroelectronics and made available on the
STM32F4 Discovery and the
STM32F429 Discovery kit boards.
Specifically, there are low-level device drivers, higher-level component drivers,
small demonstration programs for the drivers, and larger example applications.
Component drivers are those that are implemented using the lower-level device
drivers (e.g., SPI or GPIO), such as the gyroscope and accelerometer on the
The small driver demonstration programs and the larger applications programs are provided as full projects, including GNAT project files, and are ready to build either within GPS or on the command-line.
Not all devices defined by the Reference Manual are supported, and not all those supported are complete. We encourage contributions of corrections, enhancements, and new drivers.
Here is a list of projects that we are either dreaming about or already working on. If you are interested by one of those, please contact us on the project's GitHub page.
