NI Kontrol S8 Support #24

Open marceliq opened 7 years ago

marceliq commented 7 years ago

As we discussed in #19 I'd would be nice to have a daemon which expose S8 as a MIDI device and of course implementation for Ctlra. Compiling from source should not be a problem.

harryhaaren commented 7 years ago

OK Great! Lets do this. I'll write down a few steps, that hopefully will get us started. This will be a long process, and it will require that we "bounce" code and information back and forwards a few times. Its not going to be particularly easy, and I have not written a driver for a device I don't have physical access to before - but lets rise to the challenge!

After pluggin in the device, please paste the output of the following commands. lsusb and dmesg | tail -n40 and cat /sys/kernel/debug/usb/devices (Put these into seperate sections, with three "backtick" characters to have github format them nicely if possible :)

With that info, I should be able to write some code to dump any incoming USB HID packets, and then we can get started on the process of decoding the bits!

marceliq commented 7 years ago

I'm realy realy sorry. Currently I'm on a short vacation :( But I'll be back on Wednesday evening.

harryhaaren commented 7 years ago

No need to be sorry at all. We should both understand this process will take a few weeks (minimum!) so vacation, days off, and such are all very normal! I know I can be pretty enthusiastic (read above ;) but please don't feel any pressure to prioritze this.

OpenAV is a spare-time project for me - I will prioritize daily things over the S8 driver work - as should you! Enjoy your holidays, I'll get an email when you post here - so lets continue then. Cheers, -Harry

And maybe some important info: if I do cat /dev/usb/hiddev0 and move with faders/knobs, I can see "binary data" in terminal.

harryhaaren commented 7 years ago

OK Great! From the lsusb info, we can see the VendorID and ProductID from the S8: Bus 002 Device 006: ID 17cc:1370 Native Instruments. The vid is 0x17cc and pid 0x1370 in hex. This allows reading the next sections better.

dmesg gives us 3 interesting lines, informing that the device arrived, that there is a generic USB HID endpoint (as expected), that the device is the S8, and is available as a /dev/ node. Finally, one of the other USB endpoints (more on those later) shows that the audio-interface is automatically recognized by the snd-usb-audio kernel module (so it is a standard compliant USB audio interfaces: again as expected : )

The tricky part to interpret is the USB debug info, because its pretty compact. Firstly, we are not interested in the audio stuff, only in the USB HID components of the S8 for now - the other parts are not required to access (aka, the audio endpoint, the firmware endpoint etc etc).

OK - step 1 is done; initial investigation of the USB endpoints. Next step is for me to write some code, and to try get the "binary data" you refer to printing from a Ctlra application. This requires a little trickery because I obviously can't test the code here - so it might take a few attempts to get it right.

For now, I'll get preparing the code, and setting it up. I'll post here again once I have a branch pushed to Github with the initial framework of the S8 driver, and then we can work together to compile it and test it on your machine.

That's all for now!

I've duplicated the D2 driver and renamed to S8, but I do not expect anything useful from it yet. I will ping you here when there is something worth testing :)

harryhaaren commented 7 years ago

Hi @marceliq! The two commits I just pushed should print out the data of the S8, when you touch / move things. As before - I'm working blindly here, testing with another device to ensure the code works as expected, but I obviously can't test with the S8 device!

Please compile the S8 branch from git, and run the "build/examples/simple" binary. It should print ctlra_ni_kontrol_s8_connect : Connected if the USB HID connection was successful. If that happens, try moving some controls, and see if the USB HID messages are printed on the terminal.

Once I have a report back if we're good so far, we can start looking at decoding a button push-event! Cheers, -Harry

Hi @harryhaaren :) I just gave it a try, but it is not working as expected :(

build/examples/simple 

ctlra_ni_kontrol_s8_connect: Connected!
request for handle beyond available iface per dev range
ctlra_ni_kontrol_s8_connect: failed to open button usb interface

Any chance I might be helpful with that?

harryhaaren commented 7 years ago

OK no problem - there are going to be a few of these due to not working with the device directly. There is a program called usbview, apt-get install should just get it for you. Would you run it, select the S8 device on the left (probably has red-writing) and then copy-paste the text here [or post a screenshot]?

The program gives the same USB output, but in a much easier to read way. That will let me double-check the values I'm using for USB interfaces :)

Note that the first "Connected!" is already a success, so 50% aint' bad!

harryhaaren commented 7 years ago

Cool, nice work on testing! We're making pretty good progress - admittely a rough start with libUSB issues, but with Linux /dev/hidrawX access, we have HID packet data! Decoding the data is a long task - for another day! So far so good :)

harryhaaren commented 7 years ago

Hey @marceliq - open question - do you see yourself finding time to work on this with the S8 in the near-future? I'll close this for now if not. (We can re-open when there is activity again)

harryhaaren commented 6 years ago

Closing for now. Ctlra is still interested in supporting the S8 device - but it requires help from the community (from people with access to the hardware) or else OpenAV to get access to this hardware for an amount of time. Until either of those happen, this can remain closed.

andersson82 commented 5 years ago

Hi! I own a S8, and I have tried getting OpenAV-Ctlra to work in Debian today, without sucess, to see if I perhaps could help. Can you give me instructions on how to build ctrla and I will try my best to support you into getting it to work. When I follow the build-instructions it looks like it wants AVTK, but dont know where to place the lib that is created when I build AVTK. (Cloned from github)

harryhaaren commented 5 years ago

Hey @andersson82, thanks for posting! AVTK is a UI library used by OpenAV for various audio UIs (eg, ArtyFX plugins), its available here; https://github.com/openAVproductions/openAV-AVTK.

To be clear - supporting a new device is difficult, and takes a lot of time and patience - I'm happy to try help as best I can (keep in mind that I have only limited time too! : )

I've been working on a more generic method for creating device-support in Ctlra, I think with the S5 and S8 support being suggested/helped by community, maybe I need to up that to try work with.. it should be more usable than the current C code method...

Let me know if you get the AVTK dependency fixed, and we can see how S8 supports look then. Cheers, -Harry
