pinmap is a tool to help pin mapping when designing a board with an STM32 microcontroller.

It uses a database extracted from CubeMX to construct a table of all pins and associated signals. This table can be open using your favorite spreadsheet to assign functions to pins.

pinmap supports GPIO mapping using AF (alternate functions) and the old system using REMAP. The output table format differ to accommodate the differences.

Download CubeMX from st.com, and run the installation. In the installed directory, there is a db directory, copy this to pinmap directory.

To reduce disk usage, pinmap uses a compressed database, run the following command to compress it:

find . -exec gzip '{}' +
