autoconfig confusion

AtomArne

Hey Lads,

I have been troubleshootin on this for abit, and i need some help
.

I have two Microntek USB Joystick controllers, one for each player.

For some reason the joysticks a messing with me, when i setup my gamepads correctly (Gamepad1 & 2), after a reboot of the retropie, one of the players "sticks/joypads" gets inverted.

Here is the autoconfig from configs\all\retroarch\autoconfig:

input_device = "Microntek USB Joystick "
input_driver = "udev"
input_enable_hotkey_btn = "3"
input_l_btn = "2"
input_load_state_btn = "2"
input_up_axis = "-1"
input_left_axis = "-0"
input_state_slot_decrease_axis = "-0"
input_select_btn = "8"
input_select_btn_label = "Select"
input_right_axis = "+0"
input_state_slot_increase_axis = "+0"
input_r_btn = "6"
input_save_state_btn = "6"
input_y_btn = "1"
input_x_btn = "0"
input_x_btn_label = "1"
input_menu_toggle_btn = "0"
input_down_axis = "+1"
input_start_btn = "9"
input_start_btn_label = "Start"
input_exit_emulator_btn = "9"
input_b_btn = "5"
input_reset_btn = "5"
input_a_btn = "4"

As you can see the axis are clearly wrong. So player 1 is working ok, but player 2 is inverted. So i go into the "Configure input", and remap Gamepad 2 since the stick is inverted, volia, everything is fine.

Here is the new file in autoconfig which is now updated correctly:

input_device = "Microntek USB Joystick "
input_driver = "udev"
input_enable_hotkey_btn = "3"
input_l_btn = "2"
input_load_state_btn = "2"
input_up_axis = "+1"
input_left_axis = "+0"
input_state_slot_decrease_axis = "+0"
input_select_btn = "8"
input_select_btn_label = "Select"
input_right_axis = "-0"
input_state_slot_increase_axis = "-0"
input_r_btn = "6"
input_save_state_btn = "6"
input_y_btn = "0"
input_x_btn = "1"
input_menu_toggle_btn = "1"
input_down_axis = "-1"
input_start_btn = "9"
input_start_btn_label = "Start"
input_exit_emulator_btn = "9"
input_b_btn = "5"
input_reset_btn = "5"
input_a_btn = "4"

Reboot the pie..... and its apeshit again. So now playerone/gamepad1 is inverted, but the autoconfig is fine. Is this hardware or software related?

Build:
Pie 4
RP Version: 4.8.2
USB devices Microntek Zero Delay

@AtomArne and, if i remap gamepad 1, it will now invert gamepad 2.

This looks like the different wiring is between the 2 controllers. You should only have to configure one of the controllers and the configuration would apply to both inputs. Or maybe the wiring is ok - but the encoder messes up the inputs.

AtomArne

@mitu Thank you for the reply!

So, i will doublecheck the wiring. But how should i troubleshoot this? Change one of the USB encoders?

AtomArne

@mitu my man.

I just swapped out the wires from the joystick tot he USB controller, AND i swapped out the the USB controller with another. Same issue!
I just tried with one USB encoder attached, its still doing weird stuff....

Maybe the joystick orientation has affects the axis direction ?
The easiest way to test how the joystick behaves is using jstest, from the command line (exit EmulationStation).
To test P1 joystick:

jstest /dev/input/js0

and to test P2 joystick:

jstest /dev/input/js1

Move the joystick and see what the direction it's reported - should be the same for both.
Interrupt the test by pressing Ctrl+C.

@mitu Hey mitu,

OK so this is very interresting.

Tests from js0

Axes:
UP: -32767
DOWN: 32767
LEFT: -32767
RIGHT: 32767

Test from js1:

UP: 32767
DOWN: -32767
LEFT: 32767
RIGHT: -32767

As suspected, inverted.

So i have turned my joystick the wrong way when i mounted it in the machine? Are you sh.... me? :P

@mitu error 404 confirmed... jesus :)
