Project description

stm32pio

Build Status

Small cross-platform Python app that can create and update PlatformIO projects from STM32CubeMX .ioc files.

It uses the STM32CubeMX to generate a HAL-framework-based code and alongside creates the PlatformIO project with compatible parameters to bind them both together.

The GUI version is available, too (please, read this main introduction first).

Features

  • Originate the new full-fledged project in a single directory starting only from an .ioc file
  • Seamlessly update an existing project after the hardware changes by CubeMX
  • Quickly check the current state
  • Inspect tools (CubeMX, PlatformIO, etc.)
  • Clean-up the project
  • [optional] Automatically run your favorite editor or initiate a build in the end
  • [optional] GUI edition (see the dedicated README file) (please, read this main introduction first)

Requirements:

OS: macOS, Linux, Windows 7-10

Python: 3.6+

The app introduces zero dependencies by itself. Of course, you need to have all the necessary tools installed in order to perform the operations:

  • STM32CubeMX with the desired downloaded frameworks (F0, F1, etc.). All recent versions are fine (5.x, 6.x)
  • Java (JRE, Java runtime environment) for the CubeMX (already installed if the CubeMX is working). Which version is appropriate for the CubeMX you can find in its own description
  • PlatformIO (4.2.0 and above) CLI (most likely is already present if you have installed it via some package manager (pip, apt, brew, etc.) or need to be installed as a "command line extension" from the PlatformIO IDE (see its docs for more information))

If you, for some reasons, don't want to (or simply cannot) install (i.e. register in PATH) command line versions of these applications in your system, you can always specify the direct paths to them overriding the default values in the project configuration file stm32pio.ini. Check the config reference to see all possible ways of telling stm32pio where the tools are residing on your machine.

Installation

As a normal Python package the app can be run in a completely portable way by downloading (or cloning) the snapshot of this repository and invoking the main script:

stm32pio-repo/ $   python3 stm32pio/cli/app.py
stm32pio-repo/ $   python3 -m stm32pio.cli  # or as the Python module
any-path/ $   python3 path/to/stm32pio-repo/stm32pio/cli/app.py

Note: we will assume python3 and pip3 hereinafter.

However, it's handier to install the utility to be able to run from anywhere. The PyPI distribution is available:

$ pip install stm32pio

To uninstall run

$ pip uninstall stm32pio

Usage

You can always run

$ stm32pio --help

to see help on available commands.

Basically, you need to follow such a workflow (refer to the example which explains the same just illustrating it with some screenshots/command snippets):

  1. Create the CubeMX project (.ioc file) like you're used to, set up your hardware configuration, but after all save it with the compatible parameters
  2. Run stm32pio that automatically invokes CubeMX to generate a code, creates the PlatformIO project, patches the platformio.ini file.
  3. Work with your project normally as you wish, build/upload/debug etc.
  4. When necessary, come back to the hardware configuration in the CubeMX, then run stm32pio again to re-generate the code

See the commands reference file listing the complete help about the available commands/options. On the first run, stm32pio will create a config file stm32pio.ini, syntax of which is similar to the platformio.ini. You can also create this config without any following operations by initializing the project:

$ stm32pio init -d path/to/project

It may be useful to tweak some parameters before proceeding. See the config reference showing meanings for every key.

Troubleshooting

If you're stuck and the basic logs doesn't clear the situation, try the following:

  • Run the same command in the verbose mode using the -v key:
    $ stm32pio -v [command] [options]
    
    This will unlock additional logs which might help to clarify
  • Validate your environment, i.e. check whether the stm32pio can find all the essential tools on your machine:
    $ stm32pio validate -d path/to/project
    
    This will print the report about the current set up according to your config stm32pio.ini file.
  • Use the dynamic help feature which outputs information specifically about the requested command, e.g.:
    $ stm32pio new -h
    

Restrictions

  • The tool doesn't check for different parameters' compatibility, e.g. CPU/IO/etc frequencies, allocated memory and so on. It simply eases your workflow with these 2 programs (PlatformIO and STM32CubeMX) a little bit.
  • In order to add CubeMX middlewares to your build the manual adjustments should be applied, the stm32pio doesn't handle them automatically. For example, FreeRTOS can be added via PlatformIO' lib feature or be directly compiled in its own directory using lib_extra_dirs option:
    lib_extra_dirs = Middlewares/Third_Party/FreeRTOS
    
    You also need to move all .c/.h files to the appropriate folders respectively. See PlatformIO documentation for more information.
