Yeah, 10 GB update was a surprise.
I think there is tiny difference in OUT report, it seems it has 0x30 in front now.
So vibration looks like this:
0x30 0x11 0x08 0xFF ....
where 0xFF is max force
and length of OUT is bigger as mentioned in the descriptor.
So when relaying to G27 i used packer.buffer+1
And you need only first 7 bytes for G27
Edit:
Tested a G27 shifter, the byte for it is right after clutch byte (50)
byte index 51
0x0 = neutral
0x1 = 1
0x2 = 2
0x4 = 3
0x8 = 4
0x10 = 5
0x20 = 6
0x80 = Reverse
seems like bit before reverse is not used in G27 shifter since there is no gear in that spot

I finally was able to start DriveClub, and tested the firmware. It works, and the tranfers are indeed different
I captured the transfers that happen when setting the vibration level, and replayed it toward my Momo Racing wheel... and it vibrated!
I pushed the tool and the sample file here:

Awesome
When G920 (Xbox One) is out, whould be nice of someone could capture descriptors/reports, but I assume output should be similar again

Hi,
I finally got my Momo Racing FFB wheel to work with my PS4
I've posted some details on the blog.
I still have to make the code handle the other Logitech wheels.

Nice progress on integrating FFB into GIMX! Glad that community will get finally G27 support soon.
Would be nice to get hands on G920 (October 14th), to dump descriptors, but I don't think I will be able to.
That way we would have full FFB support on XB1 and PS4.

Hi,
Do you have any idea about the location of the rear gear button in the G27 input report?

Sorry, I din't check a forum in while, been busy at work recently.
I put my G27 in storage, but if you still need this info I can dig it up.
Planning to sell it anyways.

I still need this info. It would be great if you could get it.

Hi,
It also would be great if you could share your source code.
I bought an Arduino USB host shield that I should receive in a few weeks.

the reverse gear on the G27 seems to be 'implemented' in the last 3 bytes (B08, B09, B10) of the report when in native mode:
Code: Select all
B0: //identical to DFGT
0001 0000: cross
0010 0000: rectangle
0100 0000: circle
1000 0000: triangle
0000 1111: h: no button
0000 0000: h:0 up
0000 0010: h:2 right
0000 0100: h:4 down
0000 0110: h:6 left
0000 0111: h:7 up-left
0000 0001: h:1 up-right
0000 0011: h:2 down-right
0000 0101: h:5 down-left
B1:
01: r shifter / R1
02: l shifter / L1
04: wrt - wheel right top / R2
08: wlt - wheel left top / L2
80: x--- / L3
10: -x-- / select
20: --x- / start
40: ---x / R3
B2:
01: gear 1
02: gear 2
04: gear 3
08: gear 4
10: gear 5
20: gear 6
40: wrm - wheel right middle
80: wrb - wheel right bottom
B3.01: wlm - wheel left middle
B3.02: wlb - wheel left bottom
B3+B4: X axis
B3+B4: X axis: > max: 00 00 - 00 80 - max: FF FF <
B3+B4: X axis: > 90g: 00 65 - 00 80 - 90g: 00 95 <
B3+B4: X axis: > 180g: 00 50 - 00 80 - 180g: 00 A0 <
B5: accel
B6: brake
B7: clutch
B8+B9+B10: gear R?? from ~ 7D 8A 1C (idle) to ~ B0 2A 5D (engaged)
-H shifter-
[B8 B9 B10] values:
7C 8A 9C neutral
3F 94 9C left pull
BA 8A 9C right pull
7B 90 DC center push
BD 92 DC right push
C4 C1 DC right push up
B3 2B DD right push down / Reverse
it seems that there might be an axis 'hidden' in there.
I'm working on something that implements that and I'll be able to confirm this soon.
cheers
