Ok this is the code for MiKroC to read in keyboard to LCD Screen:
unsigned short keydata = 0, special = 0, down = 0,shift=1,i=1;
//char text[];
char letter,let;
sbit PS2_Data at RC0_bit;
sbit PS2_Clock at RC1_bit;
sbit PS2_Data_Direction at TRISC0_bit;
sbit PS2_Clock_Direction at TRISC1_bit;
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D4 at RB0_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D7 at RB3_bit;
sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
// End LCD module connections
unsigned char speFunction(unsigned short input)
{
switch (input)
{
case 1:
letter = "F" ;
break;
case 2:
letter = "@";
break;
case 5:
letter = "a";
break;
}
return letter;
}
void main() {
ANSEL = 0; // Configure AN pins as digital I/O
ANSELH = 0;
C1ON_bit = 0; // Disable comparators
C2ON_bit = 0;
Lcd_Init(); // Initialize LCD
Lcd_Cmd(_LCD_CLEAR); // Clear display
//Lcd_Cmd(_LCD_CURSOR_OFF); // Cursor off
UART1_Init(19200); // Initialize UART module at 19200 bps

Delay_ms(100);
Lcd_Out(1,1,"Ready"); // Write text in first row
// Wait for keyboard to finish

do {
if (Ps2_Key_Read(&keydata, &special, &down)) {}
/*if (down && (keydata != 0)) { // Backspace
let = speFunction(keydata);
