HID Remapper as Flatbox firmware

This video shows how you can use HID Remapper as firmware for game controllers like the Flatbox.
HID Remapper is a universal adapter for USB input devices.
For more information, take a look at the project's GitHub repository:

Using one as a macro pad is an interesting idea. I still have at least a couple extra rev 5s since I made a batch of 10 originally. GP2040-CE has a keyboard mode as well, and it sounds like mouse support is coming in the next release, plus you could probably put QMK on one of these since a lot of keyboards use RP2040 now, but still cool to have that option.

He's cooking

Hello. i tried to read a analog stick from a pico. i modified your v8 example (joy to mouse) and changed the adress to 0xfff4001b and 0xfff4001c as reported in monitor . but it does not work at all. i suspect the analog values doesnt match at all. is there a way to get a report on the analog values?

I've seen a fork of the flatbox with a usb port for pass through devices. I suppose that could be more suitable?

[@jfedor]

Yes! And HID Remapper does support passthrough auth for PS5 compatibility so you could totally use it for that. Or just for plugging in another controller for extra inputs.

A few GPIO pins (like gp17 and 18) does not work on pi pico . ive tried them on 2 boards with the same result.

[@jfedor]

16 and 17 are used for UART TX/RX on the default build.

[@bullzebub]

@@jfedor oh. thats unfortunate. is there any version that has 22 free gpio inputs? or do i have to recompile the source? code is really not my thing, sadly.

[@jfedor]

@@bullzebub If you flash the remapper_board_v8.uf2 firmware onto a Pico, you should have exactly 22 pins available. Plus two analog ones!
