Fixed Set_Frequency_Deviation and Send to set one bit in registers properly. Added Write_FIFO and Read_FIFO for fixed packet length cases.
1. Introduction
This repository contains drivers and sample projects to program micro-controllers with the Ada and SPARK languages. The library also provides some middleware services and drivers for external devices such as sensors. We intend this to be a location for both AdaCore and the community in general to contribute support for additional processors, platforms, and vendors.
2. Supported hardware
Ada_Drivers_Library provides support for various devices in the ARM Cortex-M and RISC-V architectures. Some devices are only partially supported. Go to the boards directory for a list of supported hardware.

3. Getting started
To start using the Ada_Drivers_Library, please go to the examples directory where you will find instructions to run your first project.
4. License
All files are provided under a 3-clause Berkeley Software Distribution (BSD) license. As such, and within the conditions required by the license, the files are available both for proprietary ("commercial") and non-proprietary use.
For details, see the LICENSE file in the root directory.
5. Requirements
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
for details.
Therefore, building with the sources requires a compiler supporting both Ada
2012 and the GNAT-defined pragma Volatile_Full_Access. For instance a recent
GNAT Pro compiler or GNAT FSF 12 for ARM ELF or RISC-V ELF (Download
here).
