PS/2 Library

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.
Library Routines
Ps2_Init
Ps2_Config
Ps2_Key_Read
Ps2_Init
Prototype
void Ps2_Init(unsigned short *port);
Description Initializes
Data line, and port pin 1 is Clock line.
You need to call either
library.
Requires Both Data and Clock lines need to be in pull-up mode.
Ps2_Config
Prototype
void Ps2_Config(char *port, char clock, char data);
Description Initializes
data
and
You need to call either
library.
Requires Both Data and Clock lines need to be in pull-up mode.
Example
Ps2_Config(&PORTB, 2, 3);
