ABL electronic PIC12 Benutzerhandbuch

mikroC provides a library for communicating with common PS/2 keyboard.The
library does not utilize interrupts for data retrieval, and requires oscillator clock to
be 6MHz and above.

making it simple...

Ps2_Init(unsigned short *port);

Initializes 

port

for work with PS/2 keyboard, with default pin settings. Port pin 0 is

Data line, and port pin 1 is Clock line.

You need to call either 

Ps2_Init

or 

Ps2_Config

before using other routines of PS/2

library.

Both Data and Clock lines need to be in pull-up mode.

Ps2_Config(char *port, char clock, char data);

Initializes 

port

for work with PS/2 keyboard, with custom pin settings. Parameters

data

and 

clock

specify pins of 

port

for Data line and Clock line, respectively. 

Data

and 

clock

need to be in range 0..7 and cannot point to the same pin.

You need to call either 

Ps2_Init

or 

Ps2_Config

before using other routines of PS/2

library.

Both Data and Clock lines need to be in pull-up mode.

Ps2_Config(&PORTB, 2, 3);
