Write VHDL code to accept input from a keyboard connected to a PS/2 port on the FPGA and output the data values of the last two transmissions to the four seven segment displays (display values in hexadecimal format). Use two seven segment displays to show the current data value and use another two seven segment displays to show the last data value. Note the order/orientation of the bits during transfer as this may come in handy during troubleshooting/debugging. In your design, pressing a key on the keyboard should be able to display its corresponding hexadecimal code on the seven segment displays.
