CubeMX + KiCAD#

This script automatically fans out MCUs in KiCAD according to the pin-out files exported from STM32 CubeMX, based on API provided by

1. Start with a CubeMX project. Other software will be supported in future. Do Pinout->Export pinout without Alt. Functions

2. Get your KiCAD schematic ready.

3. Run MCUFanout.py, enter paths to schematic file (*.kicad_sch) and the pinout file exported from CubeMX.

   Fanout Length: The length of fan-out wire, 1 unit = 50 mils (the recommended grid length of KiCAD).

   Component Key: Reference means finding the MCU component by its reference (designator), regex is supported; Value Prefix means finding by the prefix of value of components. e.g. when designating Value Prefix = STM32 the script will fan out all components with values begin with ‘STM32’, like ‘STM32F103…’ or ‘STM32H750…’.

   Enable Global/Local Label: Whether a global/local label showing the functions of pins should be created.

   With the configuration in below, the script will fan out 1000-mils-long wires with both global & local labels from component U1, according to pinout.csv.

4. Press Run, then re-open the schematic in KiCAD.

CubeMX + Altium Designer#

This script automatically fans out MCUs in Altium Designer according to the pin-out file exported from STM32 CubeMX.

1. Starting from a CubeMX project, do Pinout->Export pinout without Alt. Functions

2. Load EETools.PrjScr to your workspace.

3. Run MCUFanout.pas, fill in pinout file path, fanout length and MCU type, click Run.

4. Finished.
