cube2chibi - convert STM32 CubeMX project to board.chcfg

Hi,
I created (
another) script to convert from a STM32 CubeMX project (*.ioc) to the ChibiOS board file configuration file (*.chcfg).
It updates board.chcfg the following:
- templates path
- HSE/LSE clocks
- VDD
- ports / pins
One nice feature is that you don't need to search trough the datasheet after the alternate function number
I run the script with *.ioc found in the STM32CubeMX folder and it works.
The flow of the script is:- Parse .ioc file and create a dictionary
- Find MCU part number in the dictionary
- Parse db/mcu/families.xml and find the MCU's xml description file
- Parse the MCU xml description file
- Parse the MCU GPIO xml
- Update MCU properties from the dictionary
- Mix the information with the existing chibi config file if provided
- Save new chibi config file
Known issues:- Can't yet recognize the alternate function for the STM32F1xx family
TODO: - Convert CubeMX IPs settings to ChibiOS IPs config
The script can be found here:

Hi,
This looks really useful.
Few ideas:
- Make it an Eclipse plugin, or add it to the existing board files generator plugin as an "import settings" option.
- Do the same with RCC clock settings and create an XML that could be used to generate an mcuconf.h. Problem is that the clock tree is different in each sub-family.
Anyway, if it could be made usable from Eclipse I would gladly include it in ChibiStudio.

Hi Giovanni,
I have no experience with eclipse plugins, just a little of java, but I can look into it.
Some questions:
1. Are the sources available for the board file generator plugin?
2. How do you generate mcuconf.h? Is there an example for the xml, or a template?
Thanks,
Cezar

Hi,
All ChibiStudio plugins are available as Eclipse project here:
https://svn.code.sf.net/p/chibios/svn/b ... udio_trunkmcuconf.h is not currently generated but it could be generated exactly like we do for board files, code generation is done using a templates processor called FreeMarker:
http://freemarker.org/FreeMarker is incredibly useful and is already integrated in ChibiStudio plugins.

I'm trying to use cube2chibi, but I have got errors:
Code: Select all

I have changed to:

I was busy lately with some other projects.
The script was used with python 2.7, and I think the errors were from python 3.
I updated the script and it seems to work with python 3 as well (3.5.3).
