Before sending commands directly to the
keyboard, you should be in raw mode. In
addition, you should prefix each byte with an
escape command. If you want to send 3 bytes to
the keyboard, you must prefix each byte with
escape.
Hints
If you are using a Stamp or other
microcontroller, you may want to switch
character sets when using raw mode. Use the
$F0 command to change sets. Set #1 uses a
single-byte scan code for each key. Bit 7
indicates if the code is for make (0) or break
(1). This simplifies coding for the Stamp and
other similar processors.
PS/2 keyboards require 4 wires: two for power
and ground and two for clock and data. For
prototyping, you may find it convinient to
acquire a PS/2 connector designed to connect
PS/2 keyboards to PC motherboards (you can
find these at any place that sells PC components
for a few dollars). These PS/2 connectors
terminate in a .1” single inline pin socket. You
can either cut the wires to connect to the PAK,
or use some .1” single inline pins to make the
connection.
