The branch *master* of this GitHub repository contains ![Version](https://img.shields.io/github/v/release/arm-software/CMSIS_5?display_name=release&label=%20&sort=semver).

The [documentation](http://arm-software.github.io/CMSIS_5/General/html/index.html) is available under http://arm-software.github.io/CMSIS_5/General/html/index.html

Use [Issues on CMSIS_6](https://github.com/ARM-software/CMSIS_6#issues-and-labels) to provide feedback and report problems for CMSIS Version 5.

**Note:** The branch *develop* of this GitHub repository reflects our current state of development and is constantly updated. It gives our users and partners contiguous access to the CMSIS development. It allows you to review the work and provide feedback or create pull requests for contributions.

A [pre-built documentation](https://arm-software.github.io/CMSIS_5/develop/General/html/index.html) is updated from time to time, but may be also generated using the instructions under [Generate CMSIS Pack for Release](https://github.com/ARM-software/CMSIS_5#generate-cmsis-pack-for-release).

## Generate CMSIS Pack for Release

This GitHub development repository lacks pre-built libraries of various software components (RTOS, RTOS2).

In order to generate a full pack one needs to have the build environment available to build these libraries.

This causes some sort of inconvenience. Hence the pre-built libraries may be moved out into separate pack(s)

in the future.

To build a complete CMSIS pack for installation the following additional tools are required:

 - **doxygen.exe**    Version: 1.8.6 (Documentation Generator)

 - **mscgen.exe**     Version: 0.20  (Message Sequence Chart Converter)

 - **7z.exe (7-Zip)** Version: 16.02 (File Archiver)

Using these tools, you can generate on a Windows PC:

 - **CMSIS Documentation** using the batch file **gen_doc.sh** (located in ./CMSIS/Doxygen).

 - **CMSIS Software Pack** using the batch file **gen_pack.sh** (located in ./CMSIS/Utilities).

   The bash script does not generate the documentation. The pre-built libraries for RTX4 and RTX5

   are not included within this repository.

The file ./CMSIS/DoxyGen/How2Doc.txt describes the rules for creating API documentation.

## Contributions and Pull Requests

CMSIS Version 5 is no longer the development release. Consider to contribute to [CMSIS Verison 6](https://github.com/ARM-software/CMSIS_6) instead.

### Issues

Raise [issues in the CMSIS Version 6 repository](https://github.com/ARM-software/CMSIS_6/issues) as CMSIS Version 5 is no longer the development release.
