VESC-Project Open Source status ?

Hi VESC-Project team,

 

We are a few who are wondering what is the official open source status of the VESC Project.

Is it possible to clarify this ?

 

Hardware wize : no reference designed published and licensed yet.

On Trampa website, only software is mentioned as Open Source.

On vesc-project.com main page, not easy to figure out what is really what.

Our aim is simply providing the best and most professional open source firmware, user friendly software solutions and hardware for motor control available today

On ethos page :

The VESC-Project is meant to be the home of VESC-Tool, the VESC firmware and upcoming VESC-software products.

However, Benjamin told us in November about publishing the reference design (see thread here : http://www.vesc-project.com/node/165 ) :

I will finish it soon, sorry about the delay. Here is another link to the schematic of the VESC6 for convenience:

http://vedder.se/forums/download/file.php?id=438

Essentially the reference hw will be the vesc6, but with a rectangular PCB with SMD electrolytic capacitors instead of the through-hole ones. This way it can be wrapped in heatshrink without worrying about bending the leads of the through-hole caps.

What is the official position of VESC-Project team ?

 

Software wize : no update of firmware on Github although major changes have been done (FW 3.34) thus leading to incompatibility with external project (as the UART protocol has been changed).

Is it just an oversight ? Or will the software become closed as well ?

 

This post has only one purpose : clarify things, not charging anyone or anything.

This topic is hot, people talk a lot and are wondering what they can do, what they can't.

So please help us to clearly understand what is and will be the Open Source status on Firmware, Software and Hardware for the VESC-Project.

 

@Benjamin : again and again, tack så mycket for all your work and dedication to this wonderful project.

 

Clément

Yes, Clement, you are right, it would be kind to know when changes will be uploaded on GitHub.

Have a Nice Day.

Not uploading the latest firmware to github was a mistake by me, I just happened to forget it. It should be up to date now.

I have created a few documentation paged to hopefully make everything a bit more clear.

This is about the software in general with some links:

http://vesc-project.com/node/309

this is a tutorial for how to get started with development and build the software on Ubuntu:

http://vesc-project.com/node/310

this is some information about the hardware with links and a reference schematic:

http://vesc-project.com/node/311

 

I have been working on a new hardware version with 18 FETs that can go up to 75V and hopefully 400A, which I put higher priority on than the reference layout. Also the new mobile VESC Tool support, the NRF51822 firmware and many other things have been taking a lot of time, so I'm behind schedule on everything. Hopefully the new documentation pages can help a bit meanwhile.

I would still vote that VESC boards in general should split the control and the power stage into two connected PCBs. Then you can combine any version of Control PCB with any kind of Driver PCB.

Control PCB is the one that has the STM, the UART input etc.

Driver PCB are the MOSFETs mainly.

 

If something went wrong, the driver PCB will be damaged only. And if you want to upgrade to a high power driver you can do that. Today you have to build all into one PCB.

@wdaehn : this thread talks about the OS status, could you adress your remarks in a dedicated thread ?

@benjamin : thank you for the feedback. Knowning that you're working on a new VESC is really exciting !

But about the Open source official status, do you confirm that software (VESC Tool), 3.xx firmware and 6.4 Hardware will be ALL open source ?

Thanks for the clarification and thank you also for the documentation.

It will help a lot with it !

@JL2579

I changed the permissions on the pages, I think the links work now. Don't know why the had the wrong permissions by default.

@Clément

There are some details in the linked hardware documentation text. A short summary:

  • The VESC firmware and VESC Tool are and will stay open source.
  • The VESC 6 schematic is open source, and available on the hardware documentation page along with other open hardware designs.
  • The VESC 6 layout and gerber files will not be released to the public, for reasons explained in the hardware page.
  • A complete 3 shunt reference layout kicad project, very similar to the VESC 6, will be released as soon as I have time.

Thank you very much, the links all work fine now and the  last statements made everything very clear. What is your policy regarding contributing to the original project ? I made a seperate post regarding a boost a feature I added and a bug I spotted in the current firmware, I was wondering if and how this or other features I already have in mind could be added if you agree, so as to not have many different branches and versions of the project.

Thanks for reminding me about writing a contribution page, I will do it in the next days. I think the easiest way is to clone the project on github, make the changes and then make a pull request. Then I can give the changes a try and accept the request, or suggest some improvements. It would also be nice if you can merge your commits into one to make it easier to follow what your contribution does, because the addition and removal of the extra adc app is a bit confusing when following the changes. Here are some resources on that

Thanks, I will follow that, I am completely new to github and QT and used both for the first time this week,so of course there is still something to learn ;)

Thank you Benjamin for OS statements.

Everything's crystal clear now.

I've read the hardware documentation, and it really makes sense about gerber files.

Hello Benjamin,

 

When you wrote that you were working on a new hardware version that can go up to 75V and 400A mine eyes started blinking....And i bet, i'm not the only one!

200 AMP is more then enough  :)

Hope to see that in a near future!

Congratulations for everything you been making, and continue doing it!!!

 

Best Regards

For info.

Lebowski is working on a similar project (Endless Sphere).

He will do a power board with a Piggy-back plug-In processor board.

Some ideas for Benjaminwink

Have a Nice Day.
