Rumble support
We can send rumble events to the physical controller just fine, but we are not currently supporting rumble features in the evdev end so games cannot actually use rumble.
Do you have any links explaining why evdev doesn't support rumble? Is there any way around this you've seen?
Evdev itself would allow rumble (force feedback) support. See this for information about it. However, python-evdev doesn't seem to support rumble, or at least it didn't in the past. Here is an old pull request discussing that.
Hi! This is my code for send vibration in gamepad in python (works with xbox 360 controller, dualshock 4, wii remote).
import fcntl, struct, array, time
EVIOCRMFF = 0x40044581
EVIOCSFF = 0x40304580
LOG_CLASS_ON = False
TIME_DELTA = 250
class Vibrate:
def __init__(self, file):
self.ff_joy = open(file, "r+")
def close(self):
self.ff_joy.close()
def new_effect(self, strong, weak, length):
effect = struct.pack('HhHHHHHxHH', 0x50, -1, 0, 0, 0, length, 0, int(strong * 0xFFFF), int(weak * 0xFFFF))
a = array.array('h', effect)
fcntl.ioctl(self.ff_joy, EVIOCSFF, a, True)
return a[1]
id = a[1]
return (ev_play, ev_stop)
def play_efect(self, id):
if type(id) == tuple or type(id) == list:
ev_play = ''
for i in id:
ev_play = ev_play + struct.pack('LLHHi', 0, 0, 0x15, i, 1)
else:
ev_play = struct.pack('LLHHi', 0, 0, 0x15, id, 1)
self.ff_joy.write(ev_play)
self.ff_joy.flush()
def stop_effect(self, id):
if type(id) == tuple or type(id) == list:
ev_stop = ''
for i in id:
ev_stop = ev_stop + struct.pack('LLHHi', 0, 0, 0x15, i, 0)
else:
ev_stop = struct.pack('LLHHi', 0, 0, 0x15, id, 0)
self.ff_joy.write(ev_stop)
self.ff_joy.flush()
def forget_effect(self, id):
if type(id) == tuple or type(id) == list:
for i in id:
fcntl.ioctl(self.ff_joy, EVIOCRMFF, i)
else:
fcntl.ioctl(self.ff_joy, EVIOCRMFF, id)
f = Vibrate("/dev/input/event14")
p = f.new_effect(1.0, 1.0, TIME_DELTA )
f.play_efect((p))
time.sleep(TIME_DELTA / 1000.0)
f.stop_effect((p))
f.forget_effect((p))
@kharlashkin Hi. Are you saying you are able to get rumble to work with this code? If so, what file is this that you have provided? I would like to add it to get rumble to work if possible. Thanks!
@Millsionaire Hi! You must write only correct "/dev/input/event14" for testing this code. Sorry for my english.
Hi,
for me the ds4drv correctly creates /dev/input/event0 (raspberry pi 3). However, fftest cannot play any rumble effects ("Error: function not implemented").
The code posted above does not work ("invalid argument").
How can I make the controller rumble? Any working c code/program is appreciated.
@kharlashkin
with your code:

any hint?
is a DualShock 4 20th anniversary edition
In first you must find your gamepad in "/dev/input/eventXX" and insert true event. For testing vibration in terminal try:
fftest /dev/input/eventXX
I think autofind true event try make with glob.glob('/dev/input/event[A-Za-z]*'). Sorry for my english.
you mean like this?
[1036906.183060] input: Sony Computer Entertainment Wireless Controller as /devices/virtual/input/input119
from dmesg
note: using python-evdev 0.6.4
I don't have any dualshock for testing, but I'm sure - when dualshock 4 connect with cable to PC - its has vibrate from fftest /dev/input/eventXX. One of my friend test this.
On my example I dont use any python-evdev. Documentation for writing this test program Im getting in Linux Kernel.
ok. tested with fftest from linuxconsole package
only works throught USB cable
fails with BT due unimplemented function

same output with ds4drv --hidraw (with USB cable) (/dev/input/event25)
EDIT: oh, is a python2 (fails with python3) script..... ok. now works.
fails in BT mode throught ds4drv (plain bluez)
works in BT mode without ds4drv
Yes. I posted my script with idea to developers added vibration in ds4drv.
Yes, I can add python3 support, but now I dont have a gamepad for testing.
For anyone looking for Python 3 support: Just change line 11 to this:
self.ff_joy = open(file, "r+b", buffering=0)
Thanks for the Vibrate Class Kharlashkin
This is my output on Fedora:
File "rumble.py", line 53, in <module>
p = f.new_effect(1.0, 1.0, TIME_DELTA )
File "rumble.py", line 20, in new_effect

OSError: [Errno 38] Function not implemented
@kharlashkin do you still need some testing for this? I can be a tester for this feature ;)
