VHDL Communication With A PS/ 2 Keyboard

— by

Thanks to reader Hamster, who submitted this peachy Wiki page!  Hamster has written some VHDL code for communicating with a PS/ 2 keyboard that can be found on the wiki!  Useful stuff:

“It has lots of features:

  • It does full start bit, stopbit and parity check
  • … deglitches the signals, by requiring a state change of longer than 1us before it is acted upon
  • Checks that the clock speed is within limits
  • Can be adapted  to stuff keyboard scan codes into a FIFO for later processing.”

You can check out Hamster’s code here.

If this is up your alley, give it a try, and post your results in the comments thread.  Suggestions or improvements?  Thanks again Hamster!
