32F429IDISCOVERY board file

[tronicgr]

Hi,

Does anyone found time to make a board file for the STM32F429I DISCOVERY?

I'm using Chibistudio and I would like to try UGFX on that awesome board I have sitting on my desk.

Thanks

Thanos

Hello Thanos,

Sadly we didn't find any time to create any board files for that board yet. However, somebody of the ChibiOS/RT community already contributed the LTDC HAL. Therefore it shouln't be too hard for you to wrap the HAL around the GDISP board file interface.

If you created the board files, please share them to the community. We would LOVE to officially include the support for the STM32F429i-Discovery board into the repository.

I'll try to make a wrapper board file.

I'm using sourcetree to import your https://bitbucket.org/Tectu/ugfx/src to my pc locally. I never done merging before, when I get some results I'll try to do a push, or ask more details how it can be done. (if anything I could send you the files by email...).

Thanks

Thanos

Sounds good. Note that you have to use the ChibiOS/RT community repository in order to have the LTDC HAL.

It's still the better option to use the git repository as many changes happen to the project. You are always on the latest 'version' that way. It also simplifies the contribution process especially if you change files, rather than adding new ones.

If you need any help, let us know. Otherwise adding the works as a .zip here or send it per e-mail will always do the trick.

Thank you very much in advance for your work. Please let me know about any progress, I can't await it! :shock:

Ok, I managed to fix my installation issues... So far it looks its compiling with only a few warnings:

I'll have a change to try it on the actual board tomorrow, probably won't display anything :lol:

I tried the demo from the ChibiOS/RT community repo myself two weeks ago and it worked just fine. From there it should be easy to create a board file.

Keep us up to date

I tried the demo too, works fine. But so far I only get a bright white screen for my try with ugfx. I'll have to dig more into that.

Thanks

What exactly did you do? I recommend you to use the provided driver until you get it working. After you got uGFX working, you can use the ILI9341 driver from the uGFX repository. This keeps out problems

Hi,

You are right, I was trying to use the ILI9341 driver from the uGFX repository. But the driver on the STM32F429i is using RGB and SPI connection. I'm trying to figure out if I can only use SPI for now and how. The pinout is somehow different from normal SPI interfaces and can't find much info anywhere except from the the LTDC demo example. So many files to go through...

I'll keep trying...

Thanks

Thanos

I am not sure if you can really use the SPI interface on that board. I'd recommend to use the driver in the ChibiOS/RT repository until you get it working - from there it should only be a matter of changing a few intialization parameters to use the uGFX one.

Sorry, not yet. Being really busy last week with my day job. Working overtime (11 hours) as we expanding our farm from 600 currently to 1000 devices (windows phones )

Thanks for the link. I already have the driver files. The board file is the one that is missing and needs lots of work to put pieces together... and lots of time for debugging...

At least on the link you gave, there are more details about the connections and the interface!

Best Regards,
