USB4MAPLE adapter

[fafadou]

Is it possible to use pi zero w, instead of a pico ?

[megavolt85]

it is not rational to use an expensive mini pc for such a simple task

I just got a USB4MAPLE in, it's a really cool device. I also have a VM2, and I can't help but wonder if it could be possible to use it over USB with the splitter? Gotta dream, thanks for the hard work

Does anyone have firmware for the Raspberry Pico to work with the Dreamcast joystick on Windows 10?

Hey ya'll first post here on the forums but I figured I'd go through a quick build for my specific scenario.
End goal was to get my Flatbox rev4 (GP2040-CE https://gp2040-ce.info/) to work on my Dreamcast for Street Fighter 3

Decided to try to build one of these, originally with a kind of odd version of the rp2040 https://circuitpython.org/board/vcc_gnd_yd_rp2040/
Which ultimately did NOT work, still unsure as to why, I might give it another shot with the other adapter cables I purchased but the controller wasn't getting power.

I ended up scrapping it and just going with a RP2040-Zero Mini from waveshare, which worked like a charm. https://a.co/d/auinnCx
I was unwilling to sacrifice a DC controller for the plug so I picked up a couple extension cables https://a.co/d/43NJYiS
The colors of these obviously didn't match the original so it took some dismantling to figure out connection, If I had a voltmeter I probably could have figured it out without taking it fully apart but figured out the following

(5 is white, but obviously white/white doesn't work in paint)

After flashing the firmware and soldering I got this ugly monstrosity all set

In my experience the only way I could get my Flatbox controller to work was to put it in PS3 mode. I tried DS4 mode which didn't work but my actual DS4 worked just fine. /shrug
Another thing I noticed was by default the Flatbox default profile sets up the third buttons (usually Heavy kick/Punch) to R1/R2. Since DC doesn't have those it would just input R for both. I had to remap one of them to L1/L2 to line up well with the SF3 controls

I'll probably end up getting a usbc->c cable and design some kind of 3d printed enclosure to put this thing in but for now it works, thank you for the hard work and I just wanted to share a successful build in 2024 with kind of an odd use case

Thanks for sharing - we like to hear about user's experience!

yes, this board was designed by some idiot, but there is a solution, you need connect power to Vin and short two pins on diode

Where at on the board would one do that? I've got 3 or 4 of them I can dig out of the trash if they're actually usable.

open the photo, there is a double diode near the type-c connector, I marked with a red stripe which two legs need to be shorted.

Idk how I missed that, I'll give it a shot this weekend
