cube2chibi - convert STM32 CubeMX project to board.chcfg

[crispus]

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:

1. Parse .ioc file and create a dictionary
2. Find MCU part number in the dictionary
3. Parse db/mcu/families.xml and find the MCU's xml description file
4. Parse the MCU xml description file
5. Parse the MCU GPIO xml
6. Update MCU properties from the dictionary
7. Mix the information with the existing chibi config file if provided
8. 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: https://github.com/cburlacu/cube2chibi

Suggestions / issues / patches / forks / pull requests are welcome

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_trunk

mcuconf.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.

Very nice, I'll have a look

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

Code: Select all

d:\tmp\cube2chibi-master>python cube2chibi.py

Traceback (most recent call last):

                                         ^

I have changed to:

Code: Select all

 print ("Invalid description - %s / %s " % (self.Pin, signal))

next:

Now I have

I don't have idea how to fix it . Can you help ?

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).
