Library Example
This simple example reads values of keys pressed on PS/2 keyboard and sends them via USART.
unsigned short
keydata, special, down;
void
main() {
CMCON = 0x07;
// Disable analog comparators (comment this for PIC18)
INTCON = 0;
// Disable all interrupts
Ps2_Init(&PORTA);
// Init PS/2 Keyboard on PORTA
Delay_ms(100);
// Wait for keyboard to finish
do
{
if
(Ps2_Key_Read(&keydata, &special, &down)) {
if
(down && (keydata == 16)) {
// Backspace
// ...do something with a backspace...
}
else if
(down && (keydata == 13)) {
// Enter
Usart_Write(13);
}
else if
(down && !special && keydata) {
Usart_Write(keydata);
}
}
Delay_ms(10);
// debounce
} while (1);
}
