Mame DEADZONE with Analog Controller

icebear81

@mahoneyt944 Thanks for the help. Installed Mame2003-plus. From the game, I went into Retroarch QuickMenu and adjusted the deadzone from 20 -> 5.

From there I tried Star Wars without the xboxdrv .. target still goes from center to edge in one quick jump. I then added the device as a xboxdrv (below). Going back to Star Wars, the original controller was no longer registered - this is good, as prior, this was never the case.

I configured the Input for this game and it found a new device (RP4 over RP3 previously). Good news so far, as something at least is different.

From there, tried the controller, and still center to edge as it just seems to think the deadzone is there. I looked at the Analog Controls and Y was at 70% sensitivity and X 50% ... Adjusting those didn't seem to affect anything.

Any other thoughts -- I thought this may have worked ... Really appreciate your assist here.

@icebear81

at command prompt try

evdev-joystick --l

if you see your yoke listed, try

evdev-joystick --s /dev/input/event*

where * is the number of your controller (eg event0). If you see a figure for flatness, thats the deadzone. You can set it to zero with this:

evdev-joystick --e /dev/input/event* --d 0

see if you can get that far.

@wstanek said in Mame DEADZONE with Analog Controller:

evdev-joystick --s /dev/input/event

looks like it is already set to zero .. the thing that is tripping me up, is ... is mame actually using this device and these settings ...

Attempting to play now ....

@wstanek thanks for the tips .. but that didnt seem to make any difference.
I ran it for the xboxdrv, tested, and then killed xboxdrv and re-ran/tested

## xboxdrv then test
evdev-joystick --e /dev/input/event9 --d 0

## raw controller
evdev-joystick --e /dev/input/event2 --d 0

maybe I missed something ?

wstanek

@icebear81 Try going through all the events, I'm not sure that event9 is the right one.

I used Advmame and had the deadzone problem. I'm trying to find my notes and the guy who helped me solve it.

icebear81

@wstanek Thanks!

event4 is the raw yoke (this was earlier event2 but this changes during reboot as devices come online)

I: Bus=0003 Vendor=32be Product=1402 Version=0111
N: Name="Baolian industry Co., Ltd. BL flight yoke #1"
P: Phys=usb-3f980000.usb-1.5.1.4/input0
S: Sysfs=/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.5/1-1.5.1/1-1.5.1.4/1-1.5.1.4:1.0/0003:32BE:1402.0005/input/input4
U: Uniq=8D6D17A65548

B: PROP=0
B: EV=1b
B: KEY=ffff 0 0 0 0 0 0 0 0 0
B: ABS=3
B: MSC=10

now there is also event5 which is when the GRS Yoke is enabled in mouse mode

I: Bus=0003 Vendor=32be Product=1402 Version=0111
N: Name="Baolian industry Co., Ltd. BL flight yoke #1"
P: Phys=usb-3f980000.usb-1.5.1.4/input1

B: PROP=0
B: EV=17
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=103
B: MSC=10

event9 is when I grab the raw event as an xboxdrv

Your Xbox/Xbox360 controller should now be available as:
  /dev/input/js4
  /dev/input/event9

I could very well me muxing something up --

icebear81

Quick update, maybe this will give more info ...

After doing the above, when I add the xboxdrv device as the input in Star Wars, it now associates as R4 HAT

Looking at the event details, that has a -1,0, 1 range .. so .. if anyone knows how to disable Mame from grabbing that device over the ABS_X and ABS_Y

    Event code 0 (ABS_X)
      Value      0
      Min   -32768
      Max    32767
      Fuzz      16
    Event code 1 (ABS_Y)
      Value      0
      Min   -32768
      Max    32767
      Fuzz      16

    Event code 16 (ABS_HAT0X)
      Value      0
      Min       -1
      Max        1

Again, at this point, Im not sure if Im supposed to be using the xboxdrv or the raw device -- thanks for the assist

Robbiedog

I have the exact same problem, any direction is all or nothing.
I assumed the yoke has been seen as a digital device rather than analogue?

icebear81

@robbiedog Yeah ... the more I dig into this, the more I think you are correct that its seeing the controller as digital and not analog -- and its not actually a deadzone issue.

wstanek

Did you guys run jstest?

jstest /dev/input/js*

icebear81

@wstanek said in Mame DEADZONE with Analog Controller:

jstest /dev/input/js*

Was just thinking about this, Ive been so focused on running evtest (which appears to be returning as expected0... Ill do this and see .. Is there something I should be looking for?

icebear81

@wstanek -- seems legit

Driver version is 2.1.0.
Joystick (Baolian industry Co., Ltd. BL flight yoke #1) has 2 axes (X, Y)
and 16 buttons (Trigger, ThumbBtn, ThumbBtn2, TopBtn, TopBtn2, PinkieBtn, BaseBtn, BaseBtn2, BaseBtn3, BaseBtn4, BaseBtn5, BaseBtn6, ?, ?, ?, BtnDead).
Testing ... (interrupt to exit)
Axes:  0:-32767  1:-32767 Buttons:  0:off  1:off  2:off  3:off  4:off  5:off  6:off  7:off  8:off  9:off 10:off 11:off 12:off 13:off 14:off 15:off

mahoneyt944

@icebear81 This might sound obvious, but did you try contacting GRS? I'm sure they have extensive experience setting up their product in mame.

Robbiedog

@mahoneyt944 he does a lot of video's with Wagner's tech talk, the yoke/Pi setup video is "coming soon", I'm not sure if icebear contacted him (email is on the back page of the manual), but I was waiting for that. I might email him...

icebear81

@robbiedog I have ... no reply yet .. Im tweeted also this AM .. and also asked on the Kickstarted comments page. Ive covered 85% of means at this point .. .

I may try to use an encoder on the other connectors to see if it gets seen/behaves different

icebear81

@robbiedog you should also reach out.

wstanek

@icebear81
When you run jstest, did you see numbers responding to yoke movement? You should have seen the deadzone manifest itself.

I'm running Advmame 1.4, I have these lines in my .rc file:

input_map[p1_dialx] joystick[2,stick,x]
input_map[p1_dialy] joystick[2,stick,y]
input_map[p1_lightgunx] joystick[1,0,0]
input_map[p1_lightguny] joystick[1,0,1]
input_map[p1_mousex] joystick[2,stick,x]
input_map[p1_mousey] joystick[2,stick,y]
input_map[p1_paddlex] joystick[2,stick,x]
input_map[p1_paddley] joystick[2,stick,y]
input_map[p1_pedalbrake] auto
input_map[p1_pedalgas] -joystick[2,stick,y]
input_map[p1_pedalother] auto
input_map[p1_stickx] joystick[2,stick,x]
input_map[p1_sticky] joystick[2,stick,y]
input_map[p1_stickz] auto
input_map[p1_trackballx] joystick[2,stick,x]
input_map[p1_trackbally] joystick[2,stick,y]

I've mapped several inputs to my yoke, even pedalgas, which can be used for playing Spyhunter or some such.

Read this thread. Its about how to amend a rule for your device there.

icebear81

@wstanek re: jstest .. yes it went from 0 to +/- 32767 (as expected -- I guess) .. I did not see the deadzone manifest, or at least did not notice it or no where to look for it .. output pasted was everything ..

I will read through that thread .. thank you
