Generate CMSIS Pack for Release
This GitHub development repository contains already pre-build libraries of various libraries (DSP, RTOS, RTOS2). These libraries are validated for release.
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 Software Pack using the batch file gen_pack.bat (located in ./CMSIS/Utilities). This batch file also generates the documentation.
CMSIS Documentation using the batch file genDoc.bat (located in ./CMSIS/Doxygen).
The file ./CMSIS/DoxyGen/How2Doc.txt describes the rules for creating API documentation.
