I have to build a hardware keylogger for a school project but i have searched the internet and came up with nothing.The project is simple,i just want to record all the keystrokes and store them in a text file(or any other kind of file) on a memory card so i can retrieve them later.If anyone can help with links,tips,documentation...
You only need to understand PS2 keyboard interface which is well documented in the internet. Projects dealing with PS2 interface also can be found at EDAboard.
