For my project, I need a bunch of buttons. I knew I can do this by using multiplexer in matrix layout. But since I have PS/2 keyboard laying around, I want to use it.
I use PS2Keyboard library from the playground. From the 'Simple_test' example, I knew that the available read method will return a char type.
My Question is : how to get the original keyboard scan code ( something like 'MAKE' coloumn at http://www.computer-engineering.org/ps2keyboard/scancodes2.html) ?
I think I need to write another method as member, but I'm not good in C
