43 ## Generate CMSIS Pack for Release
45 This GitHub development repository contains already pre-build libraries of various libraries (DSP, RTOS, RTOS2).
46 These libraries are validated for release.
48 To build a complete CMSIS pack for installation the following additional tools are required:
49 - **doxygen.exe** Version: 1.8.6 (Documentation Generator)
50 - **mscgen.exe** Version: 0.20 (Message Sequence Chart Converter)
51 - **7z.exe (7-Zip)** Version: 16.02 (File Archiver)
53 Using these tools, you can generate on a Windows PC:
54 - **CMSIS Software Pack** using the batch file **gen_pack.bat** (located in ./CMSIS/Utilities). This batch file also generates the documentation.
56 - **CMSIS Documentation** using the batch file **genDoc.bat** (located in ./CMSIS/Doxygen).
58 The file ./CMSIS/DoxyGen/How2Doc.txt describes the rules for creating API documentation.
