USB4MAPLE adapter

Thanks for the info! At least now I know Tiny usb should work and I’m doing something wrong

give me a little more information about your project, what exactly it should do, how the rp2040 cores are used, what USB are you using, hardware or software?

In the Arcade cabinet world most common way to Connect their buttons to a pc or emulators is using a device that convert these buttons into 1 HID keyboard protocol then got inspired by your project and had an idea about converting this HID output to act as a dreamcast control, but faced issues to debug because was my first rp2040 project and i was stupid soldering a Wire in my handmade pico probe device, so after confirming you were using same library it made me recover the hope, digging found the issue in the probe device and after fixing , found maple bus comunication running in core 1 was going to panic when mounting a usb device, because core 0 was bussy longer than expected, only needed to modify to wait for core0 and now is working!! Thanks for Inspiring me and help me confirming I was on the correct path! Now I Can say i own a “Naomi” cabinet LOL

Is it possible to use something like the Logitech Unifying Receiver with USB4Maple? The problem of course being that you can have multiple devices plugged into a single receiver.

**EDIT** yes, you can! You just have to make sure only one device is on at a time, and it doesn't seem to work with mice; keyboards only. Tested and confirmed working with a Logitech K520.

**EDIT 2** does not work with the Logitech Bolt receiver.

Any word on Sinden Lightgun support?

I think I would want to sell these, but the cost of many of the internal parts make it pretty impossible to put up a good price.

PMd on here and in private email. 100% looking to buy if you do sell for a price that suits you.

I put them up on my Etsy shop. I emailed you the link.

Any word on Sinden Lightgun support?

lightgun support is impossible.
to implement lightgun I need to switch to using rp2350, but this is beyond the budget adapter.
as for Sinden Lightgun, this product requires quite a lot of computing power to determine the position of the sight, I don't think that cheap microcontrollers will be able to process its signal

it's fixed in latest firmware

Thank you, this issue was really bothering me and I truly appreciate the fix.

There's a feature I'd like, btw, could you have it where the VMU emulation can work without a controller? I like to use a Dreamcast controller and have the usb4maple on the side to save to. maybe even make it emulate two VMU's but maybe that's too much?

oh, and I made my second batch of these wonderful things:

Has anyone looked into the Nintendo Switch Pro Controller? It has very weird reporting in Windows. It works fine in Steam, but in the Windows Game Controllers menu, it's nothing but errors and phantom inputs.

Now I don't have a Switch Pro Controller, so I can't get you exact UART logs... but I do have a Switch Pro Controller emulator, which I have a GameCube controller plugged into:
https://github.com/DavidPagels/retro-pico-switch

The reports I get from that are odd; and since it's supposed to emulate an actual Switch Pro Controller, it's probably exactly the same.

Code: Select all

HID device address = 1, instance = 0 is mounted
HID Interface Protocol = None VID = 057E PID = 2009
HID has 1 reports
VID = 057e, PID = 2009
Protocol 0

Firstly, you'll notice the second hex group is nothing but asterisks. This number is constantly changing, and not reflective of any button presses, so I've omitted it.

Next, you'll see t he L/ZL and R/ZR buttons. The L and R triggers are `8#` during all levels of activation; then when pulled fully, they trigger ZL and ZR respectively at `4#`.

As for the HOME button, the controller doesn't have one. But the author of the software programmed it so that if you hit ZR+ZR+START, it activates the HOME bit, which is `1#`. The GameCube controller does not have a SELECT/MINUS button, but I would guess it's probably `#1` or `#4`

The sticks are where thing's get complicated. Each stick controls three hex columns and I can't understand the rhyme or reason for them.
