edwinb 0:3774ff2f9a59 1 /* This is my first project with the mbed. I have just collected libraries together
edwinb 0:3774ff2f9a59 2 and came up with the mash up below. The keyboard input is received by both the
edwinb 0:3774ff2f9a59 3 terminal and the LCD connected to the mbed.
edwinb 0:3774ff2f9a59 4 the PS/2 wiring is as follows
