Hi Carlos,
Following you will find the full set of PS2 scancodes. All you need is to reproduce and transmit
the corresponding code accordingly with itīs function. Take in mind that it is mandatory to generate
and transmit a code when a key is pressed and another code when the key was released.
| Code: |
US 104-key keyboard, scancodes for PS2
"Make" code is generated when key is pressed.
"Break" code is generated when key is released.
Hex value of make code for each key is shown.
All keys:
one-byte make code = nn
one-byte repeat code = nn
two-byte break code = F0nn

Humberto,
Vos tenes alguna rutina en C para poder conectar un PIC al puerto PS2 PC y enviar caracteres como si fuera el teclado?. Es mas este PIC debe estar entre el teclado y la PC, imaginate un lector de codigo de barras o banda magnetica que se conecta asi y le mandan los caracteres a la PC que obtienen de su lectura.
Espero que puedas ayudarme, muchas gracias. |

Roughly translated:
Do you have some routines in C to be able to connect a PIC to a PC's PS2 port and send characters as though it was a keyboard? This PIC should go between the keyboard and the PC. Imagine a bar code or magnetic stripe reader that will send the characters to the PC from the data that it obtains from its reading.
I expect that you can help me, many thanks.

Mark,
You are very kindly for translate this thread. As you can guess, Spanish is my natural language
but I make the effort to try to communicate in English because I don't want to betray the spirit of
this board which is to share our knowledge and experiences in a common language.
Anyway I just send a private message to cfernandez regarding the thread.
Thanks again and people like you are the responsible that made of this board one of the
most genuine discussion of embedded C systems.
Humberto  |

| I understand the reason that some post in their native language. However, they will get the most responses if they post it in the language that most of the posters understand. Thanks for the praise. |
