fyi... this issue seems to be related to: https://forum.recalbox.com/topic/3265/wii-classic-controller-pro-axis-reversed

@OyyoDams said in Y axis inverted in Switch bluetooth controller:

050000007e0500000620000001000000

Thanks for the reply. I've done the modification, but the issue persist. I've done the following:
1- Access via sftp and modify the file
2- Reboot recalbox
3- Tried the emulators: snes, genesis, neo-geo and Doom. All still have the Y axis inverted.

It's strange, because in the config file the Y axis seems to be inverted in the new cnofig file, so, should work...

Any other idea?

EDIT: I have tried modifying another line, just for debugging. So I've replaced, for the same controller:

		<input name="joystick1left" type="axis" id="0" value="-1" code="0" />

By this one:

	<input name="joystick1left" type="axis" id="0" value="1" code="0" />

But also, no effect, so the X axis has not been inverted either... maybe this is not the right controller config that should be modifying?

here you have the link! https://transfer.sh/7VbNO/recalbox-support-e50530f9-944d-8056-a8ee-1278dce1bf44.tar.gz

If you want, I can raise an issue too.

@Scavy thanks a lot! I will do asap!!

@OyyoDams What do you mean by "support archive"? do you mean to open an issue in GitLab?

Sure! I will do!

Btw, I have seen that if I open a game and enter into retroarch config, I can swap direction of Y axis and then works fine, but since config is not stored, that configuration is lost when I switch to another game.

Thanks OyyoDams!

That is the first thing I tried, but no matter how I configure the joystick, the Y axis is always inverted.

I have tried in the configuration to press up the joystick when is asked to press "joy up" and still appears inverted. I have tried to press down the joystick when is asked to press "joy up", but again, the Y axis is inverted.

Maybe I should look on some config file, where I can see the exact mapping of the controller?

Hi,

I have succesfully paired a nintendo switch pro-controller (chinese clone from aliexpress), and everything seems to work fine, except the vertical axis (Y) of the analog controller. On all emulators when I press up, it goes down, and vice-versa.

Do you know how I can fix this?

Thanks a lot!

The controller tha tI am talking about can be found here.

I have found the solution!!!!!!!!!!!!!!!!
The problem was not in the converter, neither in the configuration!
The problem was due to this!!! the fu**ing hdmi wall mount that I have in the box that contains the rpi was cutting the VGA signal, so I tried to connect the HDMI2VGA adapter directly to the rpi, instead of the wall mount and... voilá! works perfectly!!!! even detects automatically the resolution!!!!

so.. conclusion: DO NOT USE ANY CABLE BETWEEN THE HDMI OUTPUT AND THE HDMI2VGA CONVERTER!!!!!!

@idarius Thanks for the explanation.
I've tried your code but... no luck! I'm always getting no signal on my TFT (LG 19inch L1953S-SF).
