Question Ashida Build: Stick and Trigger Issues

[pieta909]

Hi everyone,

I’ve just finished wiring everything for my Ashida build, but I’m running into a few issues with the sticks and analogue triggers during testing:

1. Left Stick: It only works horizontally and doesn’t register left or right inputs.
2. C-Stick: The inputs seem inverted. For example, moving it upwards registers as a downward input. Additionally, it doesn’t seem to recognize the top-left area at all, which is especially problematic since I can’t access the settings in RVLoader.
3. Analogue Triggers: These are also inverted. Pressing them fully down registers as a neutral position. Furthermore, pressing the left analogue trigger also triggers the “stick left” input.

I’ve checked the connections, and they all appear solid. I also verified continuity between the C-stick and the CX/CY pads, and everything checks out.

Does anyone have an idea of what might be causing these problems? Are there specific things I should test or recheck?

Thanks in advance for any advice or troubleshooting tips!

can you post a picture of the GC+ board soldering? even though the connections might seem solid, did you test for bridges?

I got the first two issues too on my Gboy months ago.
I needed to redownload the GC+ 2.0 configurator:

Place it inside your apps folder, open it and recalibrate the sticks. On my Gboy that helped very good. I also updated the GC+ firmware after that.

Hope that helps maybe.

For 3. do you have pictures of your soldering on the GC+ and pcbs for the buttons?

thank you! haven't had any success with the recalibration software.

heres a gif! the c stick is mirrored in some way, the left stick only registers up and down and, besides both analogue triggers being inverted, the left analogue trigger registers as left stick right input. my wiring looks good and none of the points on the gc+2 short

which kind of analog sticks did you used in your build?

which kind of analog sticks did you used in your build?

original gamecube controller sticks

 

[Darkside19]

did you used new ones or used ones?

did you used new ones or used ones?

Used ones that I've confirmed to be working flawlessly prior. I did it the exact same way during a successful ashida build prior.

Can you show the solder job and related wiring?

 

[pieta909]

Its really hard to take good pictures with everything wired up and assembled. i can confirm that everything arrives at the GC+2 and has a good connection

 

[fdraghi]

those joints look a bit cold IMO... But regardless, one thing you can try is to reset the joystick settings by holding A+X+Y during boot and see if that helps. You might have to do this a couple of thimes, I found that it doesn't always work for whatever reason.

 

[pieta909]

I have tried that multiple times but without success

 

[pieta909]

I have rechecked and tried everything recommend but it still isn't working. Any ideas on what i could do?

 

[fdraghi]

maybe having the GCD line twisted paired with GND? I had to do that to fix an issue where the controller would reset itself after a few minutes playing.

EDIT: you're 100% no doubt positive that the sticks themselves work, right? I've had brand new pots that didn't work in the past.

yes I'm sure

OKAY so i have been able to resolve the main stick problem. for some reason, the GC+ didn't receive the signal from the SX pin. there must've been a problem within the board because it didn't receive SX from the pin connector. I soldered a small magnet wire from the pin connector to SX and now that stick works!

However: For some reason the analogue L and R triggers functions are inverted. they have always been but i haven't found an answer yet. when they are in a neutral position it registers as fully down pressed. when they are physically moved down it inputs as a release. exactly inverted. any ideas on how i could fix that? where should i check for problems? Thanks!!

ok it works now. if somebody runs into this issue: try to solder the GND and 3v3 from the analogue trigger separetely with magnet wires onto the GC2+. if it still is inverted, flip GND and 3v3.
