Hi, I am learning some embedded programming. I am using Linux as my platform and I want to create a daemon program that will check if a particular device(magstrife, keypad, etc) is active. Like for example, my daemon program is running in the background, then when I make a keypress event, my deamon app will do something.

What implementation should I do to create this app? And how can I check the event of the devices?

Thanks.
