Lpc2000

Hello,
      The PC/AT keyboard has 4 connection pins, two being Vcc and Gnd, the other two being the data and the clk pins. Connect both the pins to the pins of LPC and configure them in input mode. At every clock transition read the status of the data pin and shift the bit in a register until stop is detected. You get the 8 bit scan code of the character pressed.
   
  Cheers,
   Vineet.
