I need for my raspberry a USB connected device like a button that can be color illuminated and can be pressed. I want to use it to trigger at my raspberry certain actions in sw.
I fond this https://www.ultimarc.com/usbbutton/control-interface/usbbutton/ but the SDK is not supporting linux unfortunately. "When pressed, “types” a user-configured sequence of up to 48 keyboard characters into the PC on a single press." This "typing" is in my case not usable, as its a embedded device that needs login first.
I thought I can create a simple polling sw that polls the button state if pressed and sets the LED regarding the pressing, e.g once pressed red, second pressed green, third red, ... Unfortunately the sdk is only for windows..
Does anybody has a suggestion what product I can use instead ?? Or maybe i can use the sdk also for linux somehow?
