    Using a USB Gamepad with Picoreplayer

    As per the title, could someone please give me some assistance in figuring out how i can use a gamepad with picore player please?
    I would like to hack the gamepad for its analogue joystick input functions.

    Many thanks

    You should be able to remap the EV_KEY event type 1 keys using the information from this post.

    Load the evdev kernel module
    [email protected]:~$ sudo modprobe evdev
    Find the joystick device name
    [email protected]:/mnt/mmcblk0p2/tce$ cat /proc/bus/input/devices
    I: Bus=0003 Vendor=046d Product=c216 Version=0111
    N: Name="Logitech Logitech Dual Action"
    P: Phys=usb-3f980000.usb-1.4/input0
    S: Sysfs=/devices/platform/soc/3f980000.usb/usb1/1-1/1-1.4/1-1.4:1.0/0003:046D:C216.0001/input/input2
    U: Uniq=F7FA2D56
    H: Handlers=event1 js0 
    B: PROP=0
    B: EV=1b
    B: KEY=fff 0 0 0 0 0 0 0 0 0
    B: ABS=30027
    B: MSC=10
    Run inputlircd as the tc user in an ssh session.

    sudo /usr/local/sbin/inputlircd -n "Logitech Logitech Dual Action" -m 0 -g -r 500 -f

    And in another ssh connect run irw which returns.
    [email protected]:~$ irw
    120 0 BTN_JOYSTICK /dev/input/event1
    121 0 BTN_THUMB /dev/input/event1
    123 0 BTN_TOP /dev/input/event1
    122 0 BTN_THUMB2 /dev/input/event1
    You can map the keys to jivelite action by creating a keymap file for inputlircd.

    For example:
    $ cat /home/tc/inputlircd.keymap
    Press ctrl-c in the inputlircd session and restart it using
    sudo /usr/local/sbin/inputlircd -n "Logitech Logitech Dual Action" -m 0 -g -r 500 -t /home/tc/inputlircd.keymap -f

    Press ctrl-c in the irw session and restart irw and you should get the remapped keys.

    [email protected]:~$ irw
    121 0 KEY_DOWN /dev/input/event1
    123 0 KEY_UP /dev/input/event1
    122 0 KEY_RIGHT /dev/input/event1
    120 0 KEY_LEFT /dev/input/event1
