Hi i am new to verilog and am trying to design a PS/2 keyboard
interface for a Spartan 3 FPGA on an Altium evaluation board, i have
the keyboard to host communication implemented (ie. the keyboard can
now send data to the FPGA and the key pressed is displayed on a 7 seg
display). However i am having a lot of difficulty sending data back to
the keyboard to light the caps, scroll and num lock led's via the
bidirectional data bus. I have looked at code for this on opencores.org
but just could not understand it! If anyone could explain to me how
this is done in simple verilog code or explain to me how writing to the
keyboard on opencores.org works it would be much appreciated!
here is the url for the project on opencores
