hid-remapper GPIO pins on Adafruit Feather 2040

Would it be possible to assign keystrokes to the GPIO pins? It would be nice to be able to assign keystrokes to the GPIOs for accessibility switches.

Yes, it's possible, you can set GPIO pins as inputs on mappings.

That was a dumb question on my part. I guess I just never really ventured that far down into the inputs. Sorry about that. :-)

Sorry to necro, how many gpio pins on the ada feather usbhost are exposed in the web interface? I'm constructing an arcade controller type device and want to have 12-16 buttons in my design, and use hid-remapper to allow me to write different controller profiles onto the feather.

@goathens I think there are 19 GPIO pins available for use on the Feather.

I am also using HID-Remapper to turn GPIO from an arcade cabinet to USB control. I have to cover 2 joystick => 8 GPIO 8 buttons => 8 GPIO I decided to go with a Pico as I did not identify the need for USB input. I feel that there are more GPIO exposed on the Pico than on the Feather (while both use the RP2040). But I don't know how many are supported in the code, at least I found (the 16 pin I need without problem).

Now I need to define a mapping.

I require the USB host, as I have another usb-based input device for the feather/hid-remapper to remap in combination with buttons on the GPIO pins.
