Open Source Cross Platform Driver Station; Ready for Testing
 
Have you ever been frustrated because the FRC Driver Station only runs on Windows? That is, unless you want to put lots of effort into configuring Wine or visualizing Windows in some fashion. Or, perhaps you run Windows but hate the time it takes to install the LabVIEW runtime, how bulky it is, and the boot time of the DriverStation itself. Well, hello my fellow frustrated FRC Driver Station user, I seek to alleviate these problems.

Introducing the improved Open Source Driver Station:



I have forked the project created by Gluxon, added Joystick Support, Bound the F1, Enter, and Space keys to Enable, Disable, and Estop, and Added a Joystick Setup section to the Setup tab to select Joystick order.

I realize this sounds as if it is ready to go, except that I have a problem, NONE OF IT IS TESTED... I am a college student and do not have access to an FRC robot for actual testing. This is where the Chief Delphi (and FRC in general) community comes in. While I do not currently have the resources (a Windows or Mac machine) to put together packages for use other than on Linux, anyone who knows a little about Node and Node-Webkit (I managed to learn in the 5 days I worked on this) should be able to get the running fairly easily. Packages will be made eventually though, it will just take some time...

So, I am reaching out to you guys in search of people willing to test and give feedback on what needs to be done to get the Open Source Cross Platform Driver Station in a usable state, preferably before January, so it can be used for testing actual robots during the season.

Github: DriverStation.js

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
I am in the same boat as you, despising the current restrictions placed on official frc software, and this seems like a good step in the right direction. One thing that you might want to look into is that the DS protocol is changing for 2015, rendering current implementations incompatible. See http://www.chiefdelphi.com/forums/sh...d.php?t=131048

gixxy 07-12-2014 09:37
Re: Open Source Cross Platform Driver Station; Ready for Testing
 
Yeah, I did realize that the changes to the 2015 Control System would lead to changes being required in the Node Driverstation API. Despite that, I'm confident that the old CRios and Control System will still be used for testing purposes and so the current DS protocol is still a useful thing to have implemented. If it changes alot I will probably still maintain both versions (since the difference likely won't be with the front end, but the back end Node Module.

Regardless of ANYTHING that happens though, I still want to see if I can get some teams to help test this since I cannot do it myself. (well at least not until the Winter break in 2 weeks time at the earliest). Even if the backend changes, I need to know what works and what doesn't with the Joystick System, and I can only do so much using Netcat to capture packets.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
I think that the LabVIEW simulator environment actually uses the DS protocol directly. I could probably get a windows VM setup with that environent to do some testing with.

Oh x86_4819, I like you :D

Yeah, anything you can get to me about it will help. Here is the current Driverstation API, written in Javascript (Well, the whole project is actually in Javascript): node-driverstation

I plan to setup a VM soon, but I am not sure how soon I will have the time, or a license key, to do it....

I have been trying to run it, but I get an error when trying to run it.

Is there anything I am missing here? Other dependencies? This was done on Arch Linux, with node-webkit compiled from the AUR.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
Yeah I haven't pushed the update readme yet, sorry.

You need to run these two commands first:
Code:
sudo npm install -g node-gyp
sudo npm install -g nw-gyp
Then some Arch Specific issues (I also use Arch, took me three days to get this all working... GAH)
1) The gamepad module is only compatible with up to Node 0.10, the version of Node-Webkit in the AUR is 0.10, but Node-Webkit 0.10 uses Node 0.11. So you need to downgrade Node-Webkit to 0.8.6 which, if you have run the
Code:
npm install
command you have installed in DriverStation.js/node_modules/nodewebkit/ and the executable is DriverStation.js/node_modules/nodewebkit/nodewebkit/nw which will need to be patched with
Code:
sed -i 's/udev\.so\.0/udev.so.1/g' nw
you work with libudev.so.1 which Arch has.
2) You will need to specify the --python switch for 2.7
Code:
--python=python2.7
at the end of the node-pre-gyp command since the Arch python executable is Python 3.

Hope that Helps, I am avalible until ~10:30 CDT (it is currently 7:11) if you still have problems.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
I see the problem, npm install is failing with a subtle "read ECONNRESET" that doesn't stop anything, it just keeps on going. Probably due to my terrible internet at the moment, but I can try again tomorrow morning when I get decent speeds.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
I was able to get it to compile and run successfully on Arch Linux!

Here are the commands I used:
Code:
sudo pacman -S --needed nodejs # Only necessary if Node.js is not already installed
git clone git@github.com:gixxy/DriverStation.js.git # Use https if you don't have ssh set up
cd DriverStation.js
npm install
sudo npm install -g node-gyp # Install node-gyp globally
sudo npm install -g nw-gyp
cd node_modules/nodewebkit/nodewebkit
sed -i 's/udev\.so\.0/udev.so.1/g' nw
cd ../../gamepad
./node_modules/node-pre-gyp/bin/node-pre-gyp build --runtime=node-webkit --target=0.8.6 --python=python2.7
cd ../..
./node_modules/nodewebkit/nodewebkit/nw ./
This is basically everything in gixxy's CD posts and README, put in one spot.

Everything looks like it is working, but I probably won't be able to test it on a real robot until a few days from now. If I have time, I'll try to see if I can get it to work on windows too.

x86_4819 09-12-2014 06:41
Re: Open Source Cross Platform Driver Station; Ready for Testing
 
I got it to compile/run, I just needed to have usable internet to do it. I was able to successfully use it with the LabVIEW simulator, and everything seems to work. All joystick axes and buttons are fully working!

If you can get gamepad to compile on Windows, please send that to me. I have been having a hell of a time compiling it... Thanks.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
You were right about it being difficult to compile on Windows.

I've tried everything I can atm, but I might be able to figure something out once I can fix my Windows partition to have enough free space to install Visual Studio.

I don't know if you ran into this problem but currently the build (of node-gamepad) is failing with:
Code:
C:\Microsoft.Cpp.Default.props" was not found.
which might be due to only having the Windows 8 SDK, not Visual Studio.

This is why I use Linux. :)

I am using a Windows 7 VM and it is giving me issues with being unable to find stdbool.h Isn't that just lovely...

Here is what the node-gyp readme has to say:
https://github.com/TooTallNate/node-gyp#installation
Code:
On Windows:

    Python (v2.7.3 recommended, v3.x.x is not supported)
    Windows XP/Vista/7:
        Microsoft Visual Studio C++ 2010 (Express version works well)
        For 64-bit builds of node and native modules you will also need the Windows 7 64-bit SDK
            If the install fails, try uninstalling any C++ 2010 x64&x86 Redistributable that you have installed first.
        If you get errors that the 64-bit compilers are not installed you may also need the compiler update for the Windows SDK 7.1
    Windows 7/8:
        Microsoft Visual Studio C++ 2012/13 for Windows Desktop (Express version works well)

Yes, but at least when the 2015 protocol is released we will be ready to utilize it in the front-end. (Pull the latest version of the DS and look at the setup tab!)

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
I just want to let you know that I ran it on robot today and it drove it perfectly.

I found a bug involving the robot code indicator though. When I reboot the cRIO from the DS (that's the only way I've been able to produce it), the robot code indicator does not come back on even though the communication indicator does.

When I reset the robot code status (via the Diagnostics tab) the robot code indicator turns on, but the communication and joystick indicator turn off. The list of joysticks (in the Setup tab) is also cleared. I'm still able to enable and drive the robot when this happens so it seems to just be a UI bug.

That isn't functionality that I wrote, but it SEEMS to be an issue with the form submission resetting the entire Application. I have written a potential fix and pushed it to the github, please try it out. Thanks.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
I can't test it on a robot right now, but it doesn't reset the joystick indicator or the list anymore, so it might be fixed.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
Understandable. Do test it when you get a chance though.

I am so excited to hear two different fellows say it works! Now we just need it tested on a mac or two, and get it to compile at all on Windows, then test that (which anyone could do since it should be able to run on the clamshell).

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
Great News, I got the gamepad package to compile in Windows.

I started from a CLEAN install of Windows 7 64-bit.

Installed Node.js, then installed node-gyp, nw-gyp, and node-pre-gyp globally via npm.

Installed: Python 2.7.3
Installed: Microsoft Visual Studio C++ 2010
Installed: Windows 7 64-bit SDK
Installed: compiler update for the Windows SDK 7.1
Installed: Microsoft Visual Studio C++ 2012

Ran Windows updates a couple of time (until the service pack was installed)

Installed: Microsoft Visual Studio C++ 2013 (which unfortunately requires you to sign in with a MS Live Account)

Opened my Command Prompt and Navigated to the gamepad directory.

Ran
Code:
node-pre-gyp build --runtime=node-webkit --target=0.8.6 --target_arch=ia32 --msvs_version=2013
setting target architecture because I was running a 64-bit system (compiling for 32-bit) and setting which version of Visual Studios I was using. (Note, did not work setting it to 2012 or 2010, or leaving it unset)

Now I just need a 32-bit linux compilation (which I just need to get around to) and I will have all the binaries I need to setup packages.

Whoo that was an all day process. Now to Calculus Homework.

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
Ok, I have compiled executables for every platform now!
OSX
Windows
Linux 32-bit (NLinux32 has the Missing libudev.so.0 fix)
Linux 64-bit (NLinux64 has the Missing libudev.so.0 fix)
as well as a .nw package without the node-webkit executable included (much smalled file size)

They are all located at: http://gustavemichel.com/OSCPDSPackages/

gixxy 12-01-2015 22:33
Re: Open Source Cross Platform Driver Station; Ready for Testing
 
With basic testing completed. My code has been pulled and merged into Gluxon's main project. Well done to the both of you who helped me with testing!

The Open Source DriverStation has Joystick Support! Next up seems to be to port the 2015 network protocol and mDNS to the OSDS. Please see/reference Gluxon's thread for future OSDS info: http://www.chiefdelphi.com/forums/sh...d.php?t=118768

Re: Open Source Cross Platform Driver Station; Ready for Testing
 
Thanks!
dumb question number 6: has anyone tried this on a new roboRIO yet?
Best,
Martin

gixxy 13-01-2015 08:49
Re: Open Source Cross Platform Driver Station; Ready for Testing
 
It shouldn't work with the roboRIO because we are still working on reverse engineering the new Network Protocol, and looking into mDNS support, but feel free to give it a shot. Just make sure you are cautious.
