This thread will be for open discussion (e.g., questions, suggestions, answers, what-have-you's) for those testing v3 of the driver. Please post all questions related to v3-alpha here before it becomes a release.

The relevant blog posts related to this driver:

When you first post, please list your Linux distribution, kernel version, and devices, and please try to list relevant output (e.g., with xinput test).

Anyone is welcome and encouraged to comment. Some people who have reached out already: @meelash @sparshjain265 @RaSTuS26

jlam55555 commented 4 years ago

I just received the default keycodes for all of the devices from VEIKK, and I'll try to implement them over the next day or so. When this is done, the first button should report Ctrl+Alt+Shift+Keypad 0, the second should report Ctrl+Alt+Shift+Keypad 1, etc.

I detailed why I ended up using these long keycodes in the blog post about button mapping, but I'd like any feedback on that as a design decision.

Current devices with button mapping working: A50, VK1560

Current devices with button mapping not working: A30, A15, A15Pro, VK1560Pro, VK2200 (will try to get these working over the next day or two and let you know)

In the meantime you can let me know if the pointer events are working properly with v3-alpha, and (when I've added the mappings for all of the devices) if the buttons are correctly reporting the aforementioned key combinations. (E.g., post the output of sudo xinput test [device id] (find device-id using xinput list) after pressing some buttons)

jlam55555 commented 4 years ago

Now that I've looked at the button codes, the only one that I notice might cause problems is the A15 Pro. The 5th key (third row, first button) is mapped to Ctrl, and some other buttons are mapped to Ctrl+ other buttons, which might hide the Ctrl key.

A15 Pro
+--------------------
|   _ 
|  ( ) <- dial
|   -
|
|  BTN_1  | BTN_2
|  BTN_3  | BTN_4
|  BTN_5  | BTN_6
|  BTN_7  | BTN_8
|  BTN_9  | BTN_10
|  BTN_11 | BTN_12

@sparshjain265 (Or anyone else with the A15 Pro) Can you try this:

Pull the latest changes from v3-alpha.
Compile the driver: make all uninstall install, only call uninstall if already installed
Run dmesg -w
You might have to unplug and replug in the A15 Pro to get the driver to work.
Press some keys (both single keys and key combinations), especially with BTN_5, BTN_4, BTN_11, BTN_12. Also try turning the dial left and right. Record which keys correspond with what dmesg output.
Paste the relevant output of dmesg in a comment (make sure to indicate which keys correspond to which parts).

Thanks.

Still GIMP pressure not working with 'Edit/Input Devices/VEIKK A30 Pen' enabled in screen mode, but fine in Krita.

xev doesn't report any keycodes for the buttons.

jlam55555 commented 4 years ago

Thanks @RaSTuS26. Almost everything you said is expected, and I might not have been entirely clear. (Also, I wrote xinput list but meant xinput test [device=id] (in your case xinput test 21 for the pen). xev doesn't report any keycodes for the buttons because I didn't implement the mapping for the A30 yet (again, hopefully will have a draft up by this afternoon).

For the buttons, there should be (a lot of) debugging output right now in dmesg -w whenever you move the mouse or press a button. You can experiment with this.

The only thing that's unexpected is still the GIMP pressure..... Maybe some debugging with evtest and xinput test will help with that.

RaSTuS26 commented 4 years ago

Cheers jlam55555, I didn't really expect the buttons to work from reading your notes, but thought I'd try, then report back anyway.

Here is the output from xinput:

The output from evtest:

jlam55555 commented 4 years ago

@RaSTuS26 Try again with the newest commit. A new "VEIKK A30 Keyboard" input should show up in evtest and xinput, and hopefully things will just work.

I'm reluctant to implement the A15 and A15Pro buttons before getting more feedback on the Control button, but the A30 was straightforward to implement with the current system.

(Same thing, evtest, xinput test, and dmesg outputs will all be helpful.)

RaSTuS26 commented 4 years ago

Here we go jlam55555

'xinput list' output:

    ↳ VEIKK A30 Pen                             id=21   [slave  keyboard (3)]
    ↳ VEIKK A30 Pen                             id=22   [slave  keyboard (3)]
    ↳ VEIKK A30 Pen                             id=23   [slave  keyboard (3)]

Tried all 3 id's, same output as previous (no event registered...)

'evtest' devices:

/dev/input/event23:     VEIKK A30 Pen
/dev/input/event24:     VEIKK A30 Pen
/dev/input/event25:     VEIKK A30 Pen

Again, tried all 3 inputs, no live output given.

EDIT: I did make sure the old driver was unloaded with 'rmmod veikk' before trying new versions of driver.

jlam55555 commented 4 years ago

@RaSTuS26 I believe you've compiled and loaded the version from the master branch -- this is the behavior of the V2 driver (and what the V3 driver is intended to fix).

RaSTuS26 commented 4 years ago

@jlam55555 No, definitely from the alpha3 branch, the latest commit was only 10mins old when I downloaded it. It did make a difference, I now had 3 hid-inputs instead of 1, so something did register. As mentioned I also made sure to unload previous driver with 'rmmod' before activating (replugging A30).

This is the branch link I'm using: https://github.com/jlam55555/veikk-linux-driver/tree/v3-alpha

jlam55555 commented 4 years ago

@RaSTuS26 I understand that it made a difference, but it's not the latest update. See this line: the format is different from what you're showing.

Sorry if this is a stupid question, but how did you download it? Did you make sure to run git checkout v3-alpha after downloading it? (git status should show "On branch v3-alpha")

RaSTuS26 commented 4 years ago

@jlam55555 I'm an idiot, I compiled from the old v2 directory. Now installed latest v3alpha, will report shortly.

I don't use git, just download the zip.

RaSTuS26 commented 4 years ago

@jlam55555 ok, testing now.

Yay, it's working Jonathan, great work mate.

jlam55555 commented 4 years ago

@RaSTuS26 Cheers! Now go have some fun with xbindkeys. Keyboard shortcuts like Control+Alt+Shift+KP_0 should work.

(I also realized I made a mistake with the mapping: the fourth button should map to Keypad 3 but I accidentally wrote Keypad 4. Will fix this in the next commit.)

In the meantime I'll be waiting on input from @sparshjain265 for the A15 Pro.

RaSTuS26 commented 4 years ago

@jlam55555 Have GIMP working now, didn't notice the 'Dynamics' (brush/pencil) options, my tool dock was too small to see them. Will play with that for a bit now.

jlam55555 commented 4 years ago

On a side note, will experiment a little today with a USB sniffer on Windows with the Windows driver to see if I can reverse engineer the USB packets. I really wonder if VEIKK performs the key mappings in hardware after sending some command to it since mapping like I'm currently attempting in this driver feels a little too abstruse, but I have no idea about the internals of the driver in Mac or Windows. I've asked VEIKK about it but no clear answer yet.

If there is some command to send to the tablet to remap keys that would be a godsend.

Never tried USB sniffing so most likely nothing will come out of this and this will be a spectacular fail, but who knows?

RaSTuS26 commented 4 years ago

Have fun, good luck.

@jlam55555 this looks like the undesired output (I double-checked if I have the latest commit and working in branch v3-alpha)

jlam55555 commented 4 years ago

@sparshjain265 No, this is the desired output, thank you for showing me this. I may not have been clear about this, but since I hadn't mapped the keyboard buttons yet for the A15 Pro (or the A15, VK1560 Pro, and VK2200), no events should show up in xinput or evtest yet. But there should be output for the button presses in dmesg, which is what I'm asking you for now.

I see that dmesg shows events for pen events, but does it also show button events? If it does, please annotate the dmesg output like I mentioned here.

sparshjain265 commented 4 years ago

@jlam55555 no, dmesg doesn't show button events, only pen events

Hi all! I'm using Fedora 32, kernel version is 5.7.14-200.fc32.x86_62 and I have an A30. Installed kernel libraries and ran make, ran with no errors. On sudo make install clean I get the following:

Regarding the SSL errors, I do not have Secure Boot enabled, if that is relevant. In spite of the errors, it appears to be doing something as evidenced by- (1) a leftover mouse pointer stuck on the screen in some position, with a new pointer existing and being in use. (2) /lib/modules/5.7.14-200.fc32.x86_64/extra/ has a file veikk.ko added to it, (3) modprobe veikk does not return any errors (also doesn't return any other feedback at all).

xinput list returns the following:

⎡ Virtual core pointer                      id=2    [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                id=4    [slave  pointer  (2)]

    ↳ xwayland-keyboard:17                      id=6    [slave  keyboard (3)]

I gather that's not what we're looking for, as I see the output of other users has an actuall veikk entry. For reference, the only other device connected to my machine is an apple bluetooth keyboard.

Any suggestions of what to test next?

My ultimate goal is to be able to (1) configure one of the stylus buttons to switch to a scroll mode where swiping up and down is the equivalent of a scroll wheel, and (2) Same thing but a zoom in/out mode, with the 1 being the most necessary of the two. What is the prognosis to being able to do something like this using this driver; is this a pipedream?

Thanks!

jlam55555 commented 4 years ago

@meelash

Errors are normal, looks like it's installing properly.
The differences you're seeing appear to be because you're using Wayland rather than X (I just looked it up, looks like it's the default for GNOME on Fedora.) I haven't gotten a chance to test anything with Wayland, so I'm not sure how well things should work -- you can try to switch to X11 mode when you log in to test this out (should be one of the icons on the top).
Your goal is not a pipedream! Again, with xbindkeys and something like xvkbd the keys should be easily remappable. Just make sure you have the latest version pulled from GitHub and installed, and try some of the debugging steps like mentioned here. Feel free to paste the output. Hopefully you'll be getting something similar to what RaSTuS26 is getting (also an A30, buttons are reporting the correct events).

Yep, so, after switching to x11, the output of xinput is:

I notice the key mapping on the pen changed from the default already.

After unplugging/replugging I'm getting the same results as @RaSTuS26 xinput test of the Keyboard. xinput test 8 gives no events registered. xinput test 11 give all three buttons, motion, and pressure.

Holy crap, starting to get something to work with the third, VEIKK proprietary interface after playing around with USB sniffers (wasn't expecting to get anything out of it). Didn't get very far but this looks very promising. This should eliminate a lot of the weird mapping issues with overlapping keycodes (e.g., on the A50, A15, and A15 Pro).

For reference, was sniffing using USBlyzer on Windows (trialware) and Wireshark + usbmon on Linux. The basic premise is that I noticed that when the Windows VEIKK driver was installed, the device reported different input reports from the proprietary device, which should be easier to work with. This confirms some of the suspicions I've been holding for a long time (and seems to correspond with the vague information I've been told about the third device from VEIKK). I also noticed that there was a certain set of commands (output reports) sent from the computer to the VEIKK device which seems to toggle this. I'm playing around with the exact nature of the output reports now.

At least, all I've gotten to work with the new system is the A50 Pro keyboard (not the pen yet). Will test on the other devices soon and report back.

@meelash Your output from xinput list is a little strange -- I'm not sure why the name is VEIKK A30 Pen Pen. There should only be a VEIKK A30 Pen and a VEIKK A30 Keyboard, which report their respective events (e.g., like what @RaSTuS26 showed. Not sure what's going on there; will investigate after my current USB adventures.

Update on the proprietary driver: a lot of success! The changes are now on the v3-alpha-ff0a branch (ff0a is the usage code of the proprietary HID interface). I'm lucky that between the S640, A50, and VK1560 there's a lot of variability, so I get to test out most of the features (e.g., gesture pad, rotating buttons, regular buttons, etc.).

It'd be great if we could have people test this, and show the output of evtest. Make sure you're on the new branch! What you should be seeing is the pen working normally, and the buttons and gesture pad outputting Ctrl+Shift+Alt+Meta (Windows key)+(F1 through F24). With the way it's set up now, I believe it should work for all devices that are in the driver's device id table, but of course I've only been able to test on my devices (A50, S640, VK1560).

What was achieved/decided:

Using the proprietary third HID interface (rather than the two generic interfaces from before)
Third interface uses a bitmap of keys, much easier to deal with than the pre-programmed key combinations on the generic HID interfaces, so remapping is much cleaner/easier
xbindkeys is weird (seems to lose focus of current window when pressing a key combination, so you can't enter text into the current window) so probably will make the v3 configuration tool work with Autokey (super nice Python tool with broader implications than remapping keys, has good support and documentation, and is familiar to people who've used AutoHotkey on Windows (this is the Linux port of it AFAIK)).
A lot of code restructuring and cleanup. Abolishment of the short-lived, terribly-confusing pseudo-usages!

Brief overview of changes in v3-alpha-ff0a

You don't have to read this, but here's a brief overview of what was accomplished so far (I'll probably write another blog post on this when things get a little more stable):

Sniffed USB packets while testing the pen/pressing buttons on Windows with the driver installed, saw that the events being sent were different than the ones received on Linux. (They were being sent with report ID 9, which is (you can see this with the output of usbhid-dump)). In these, the keys weren't being sent as HID usages, but rather in a bitmap (which is much more compact and logical; the first button corresponded to the first bit, the second the second, etc.).
Sniffed USB packets when plugging in the device on Windows (with driver) vs. without driver (also Linux without driver), found that there were some 9-byte packets being sent to the tablet only when the Windows driver was being used:
- 0x09 0x01 0x04 0x00 0x00 0x00 0x00 0x00 0x00
- 0x09 0x02 0x02 0x00 0x00 0x00 0x00 0x00 0x00
- 0x09 0x03 0x04 0x00 0x00 0x00 0x00 0x00 0x00
After some messing around, I discovered that if I sent these to the device (using hid_dev->ll_driver->output_report, this would then switch the internal interfaces over to sending events over the proprietary device. In particular, the first switches the pen over, the second the keyboard, and the latter the gesture pad (if applicable).
- It also turns out that if you send them all at roughly the same time, weird issues may pop up. (My guess is that the VEIKK tablet cannot process the incoming reports very quickly.) So I had to put the output_report calls in a workqueue at different delays, which solved the issue. (The length of the delays is still something to experiment with.)
It turns out that the proprietary interface emits devices with three different "sub-report types": the pen, keyboard (if applicable), and gesture pad (if applicable). To keep things simple, I gave each one of these its own struct input_dev, so now a "Gesture Pad" may show up in xinput list or evtest.
Also a whole lot of internal restructuring/refactoring of functions. With the three report types, I decided to make three input types rather than two (pen, keyboard [if applicable] → pen, buttons [if applicable], and gesture-pad [if applicable]) and creating more functions to set these up separately. It turns out that this makes the code a lot more similar to Wacom's driver now, which is kind of cool; feels like it's bringing everything full circle, and now I can more fully understand/appreciate a lot of the pieces happening there.
As part of the refactoring, I rewrote some of the functions to have more centralized exit points and made shorter functions (veikk_probe got broken down into shorter functions), both as per the kernel coding style guide.
This update greatly simplified a lot of the remapping code and the whole idea of linking the HID devices, so this gets rid of a lot of the old code (e.g., storing the struct veikk_devices in a linked list, all the pseudo-usage stuff, etc.).

I know I was messing around a while with the idea of "pseudo-usages" to make the interface consistent across VEIKK devices, and I know some (e.g., @sparshjain265) were playing around with the pseudousages table. This update abolishes that darned complicated mess. Sorry if anyone spent any time messing around with those, but this should make things much easier going forward.

Mapped them in GIMP to scroll-[direction], but I have no scroll-right.

Also was able to map buttons 1-4 to certain tool selections in GIMP no problems.

jlam55555 commented 4 years ago

@RaSTuS26 Ok, now I realize that I forgot to send the modifier keys on the gesture pad events :/ They're supposed to have the Ctrl+Alt+Shift+Meta like the other keys.

Hmm, so I tried to map the gesture pad keys to the higher-numbered function keys, but it looks like their keysyms have been overwritten as their original uses faded into obscurity (i.e., their keysyms are not F20, F21, etc., but XF86TouchpadOff, XF86TouchpadToggle, etc.).

How did you map them in GIMP? Was it through the keyboard shortcuts menu? Or was it through xbindkeys?

RaSTuS26 commented 4 years ago

@jlam55555, I used GIMP's keyboard shortcuts menu.

Dial Test (Center Button): No Output!!!

RaSTuS26 commented 4 years ago

@jlam55555 Just noticed the screen mapping of the pen on the tablet is wrong. In Y-axis things seem ok, but in X-axis left side is correct position, but reaches right side of the screen when the pen is positioned only 2/3 (approx) across, then goes off screen when moved past that.

sparshjain265 commented 4 years ago

+1 this is happening with me too

jlam55555 commented 4 years ago

@sparshjain265 Thanks for the detailed output. I'm not sure about the center wheel. The center wheel on my VK1560 reports correctly (there are seven regular buttons, and it registers as the eighth button). Extrapolating from that, I think that your center button should report as the 13th button, and I thought I accounted for it. So I'm not exactly sure what's going on in there; you may get some more information by seeing the dmesg output when you press that center wheel button.

@sparshjain265 @RaSTuS26 I didn't realize the wrong screen mapping until you pointed it out. It looks like the proprietary interface output different maximums than the generic interfaces. It doesn't seem to match up with the report descriptor (i.e., usbhid-dump, which seems to show two sets of logical maximums: 32768x32768 for the generic interfaces, and one set indicating physical dimensions), so we'll probably have to do guess-and-check by seeing what evtest reports when you go to the bottom-right of your screen. Unfortunately, unless we can find a better way, this will just have to be done manually for each device.

This is what I've found with my devices (will put in the next commit):

VK1560: x_max: 34420, y_max: 19360 (aspect ratio: 16/9)
S640: x_max: 30480, y_max: 20320 (aspect ratio: 3/2)
A50: x_max: 50800, y_max: 30480 (aspect ratio: 5/3)

These numbers do seem to have sensible aspect ratios that match their dimensions, e.g., the S640 drawing area is 6"x4" (aspect ratio 3/2), the A50 is 10"x6", the VK1560 is the same aspect ratio as a 1080p screen. This is as opposed to the generic devices, which were usually 32768x32768 despite the aspect ratios.

If you could provide the maximum values (or create PR's with them) I'll gladly welcome those.

(On a side note, I'm starting to wonder if a little bit over overscan/underscan (not sure if these are the right words) near the edges of the screen might be desirable for the non-monitor tablets. If the device is exactly lined up with the edges of the screen, sometimes it's hard to press buttons near the edges of the screen. I'm thinking about making this an option in the configuration GUI.)

jlam55555 commented 4 years ago

@RaSTuS26 I see what you mean about GIMP now. I might have to choose a range of somewhat-generic keys that are more common than F13-F24. Perhaps the keypad (KP) keys will do? (This is what I had in mind originally). E.g., something like (with the Control+Shift+Meta+Alt modifiers on top):

Buttons 1-12: F1-F12
Wheel center/left/right: KP0-2
Gesture pad two-finger tap, up, down, left, right: KP5-9

(KP3, KP4 will be available for additional keys in the future if necessary)

(EDIT: Keypad keys may be affected by num lock, which could make things confusing. I could use the normal number keys instead.)

How does this scheme sound?

RaSTuS26 commented 4 years ago

@jlam55555 In the alpha3 from 2020-08-11 the screen mapping works correctly and the mouse cursor tracks pen position. In ff0a the mouse cursor doesn't move.

Correction, if I unplug the tablet then replug with ff0a, then the mouse cursor does track the pen movement, so seems it needs to be reinitalized to work properly, mapping is still wrong though.

RaSTuS26 commented 4 years ago

@RaSTuS26 I see what you mean about GIMP now. I might have to choose a range of somewhat-generic keys that are more common than F13-F24. Perhaps the keypad (KP) keys will do? (This is what I had in mind originally). E.g., something like (with the Control+Shift+Meta+Alt modifiers on top):
* Buttons 1-12: F1-F12

* Wheel center/left/right: KP0-2

* Gesture pad two-finger tap, up, down, left, right: KP5-9
(KP3, KP4 will be available for additional keys in the future if necessary)

How does this scheme sound?

That sounds fine, the [modifiers]+F1-F4 are mapping fine. It's only the gesture pad playing up, so if they could be mapped to [modifiers]+Keypad Numbers that hopefully would work correctly.

Sometimes unplugging and re-plugging is needed after compilation, which has been a known issue for a while.
It looks like your A30 might have the same logical dimensions as the A50 (50800x30480). What happens if you change the x_max and y_max in veikk_model_0x0002 to these values? Is the mapping corrected?

Works much better, left and bottom are fine, but top is short by about 5-6 pixels and right is short by about 12-14 pixels.

EDIT: Y is fine, but X is short by 12-14 pixels.

drawing area for a15 pro is also 10"x6" and 30480 should be the max value for y but I notice that my tab is registering pen input beyond the designated drawing area, which explains the observed max value of y as 31750. Also, my tab is registering pen inputs slightly beyond the designated drawing area in the top and left boundary but is precise (at least by naked eye observation) in the bottom and right boundary.

sparshjain265 commented 4 years ago

(On a side note, I'm starting to wonder if a little bit over overscan/underscan (not sure if these are the right words) near the edges of the screen might be desirable for the non-monitor tablets. If the device is exactly lined up with the edges of the screen, sometimes it's hard to press buttons near the edges of the screen. I'm thinking about making this an option in the configuration GUI.)

@jlam55555 This sounds like a good idea, I believe instead of using 0 as min, some small positive value can be used (can be added as a parameter in the model structure?) and instead of using actual max as the max, something slightly less than max can be used in input_set_abs_params() function calls. Alternatively, the inverse (in some sense) can be done in input_abs_set_res() function calls.

jlam55555 commented 4 years ago

@sparshjain265 About the center wheel button: I just realized that I tried to do this:

buttons_state is 16 bits
buttons_state | 0x10000

I'm kind of stupid sometimes. (Either buttons_state has to be expanded to 32 bits or I have to treat that specially, since the A15 Pro is the only tablet that uses that 17th bit. Don't worry though, this is an easy fix).

jlam55555 commented 4 years ago

@RaSTuS26 I'm confused, by the looks of your numbers it sounds like your situation is very similar to @sparshjain265's and the y_max maximum is slightly above 30480 and the x_max is around 50800. Just to try it out, does setting the y_max to 31750 change anything for you? If not, can you fiddle around with the values to try to make it work, or try to get a more accurate reading of the maximum values with evtest?

(If it's 50800x31750, then it's an 8/5 aspect ratio, which is strange because it doesn't match the drawing area physical aspect ratio.)

RaSTuS26 commented 4 years ago

@jlam55555, Still didn't reach right side properly. I'm now using "x_max = 50600, .y_max = 31750" and it covers the whole perfectly.

jlam55555 commented 4 years ago

Another thing I'm starting to notice: when remapping keys on the buttons, the modifiers are great, but on the gesture pad, it doesn't work so well with Autokey. My guess is that it's because the gesture pad events are hardrepeated, which causes all of the modifiers to be rapidly switched on and off, which probably creates problems for autokey. Either I have to find out how to debounce the four gestures or switch them to key that wouldn't require modifiers. More on that later.

sparshjain265 commented 4 years ago

@jlam55555 I think the 50800x31750 (8/5 aspect ratio) is when we include the inputs received from outside the designated drawing area, and if we tried to note the min/max values of both x and y, we should get a proper 5/3 aspect ratio.

About that buttons_state, I think making it 32 bit is a better option considering new devices in the future may have more buttons.

sparshjain265 commented 4 years ago

@RaSTuS26 if you can't reach the right side properly, can you set 'x_max' to something lower and try? I have a hunch that a number lower than 50600 will help you more than a number higher than this.

RaSTuS26 commented 4 years ago

@sparshjain265, 50600 works fine, when it's 50800 it doesn't reach. My current working figures are 50600x31750.

sparshjain265 commented 4 years ago

@RaSTuS26 oh alright, I'm sorry. Yes, I meant to say less than 50800 (which 50600 is, so yay, my hunch was right).

RaSTuS26 commented 4 years ago

@sparshjain265, How does 50600x31750 work for you?

sparshjain265 commented 4 years ago

@RaSTuS26 well, I reach the right end of my screen slightly before I reach the right end of the drawing area in my tab. With 50800, it's seemingly exact.
