Hi,
Im Diego Cembal ( Electronics Engineer from Argentina ).
I need to develop, in Dynamic C language using a RCM3700, a program
that read from a serial port D the scan codes of the PC Keyboard keys
and after that decode them and generate the corresponding ASCII chars.
P.D: I need to solve this using "exclusively" a RCM3700.
Thanks in advance,
Eng. Diego Cembal

Check out the PS2KB library in the files section of this group. There are
some basic scan-code to ASCII tables as part of this library. You may need
to extend these or modify them if your keyboard is different, but they will
be a good start.
Enjoy,
Bill.

Hi Diego,
Take a look at ps2k.zip on the files section of
the page of rabbit-semi group.
There you will find what you
want...

As somebody said it yesterday, this question was already discussed here.
Check posting from William Landoline from January 21st, 2004 - it seems
ready libraries are posted on the Files section. Check for "PS/2" keyword.
Whether this will fit your 3700 or not, I am not sure. AFAIK, 3700 is quite
restricted on signals which get out of the core, so you could run into
troubles.
HTH, George

Sine he has a PS2-RS232 converter, all he needs are the tables and
supporting decoder code. The tables are pretty compact and the code is
downright tiny. Also, if a very restricted subset is required, the tables
will provide the insight required to build something simpler.
I just looked at the 3700 specs and even if he needs raw PS-2 keyboard
connections there are the necessary pins. Two pins are required - one
interrupt pin and general purpose I/O pin.
Enjoy,
Bill.
