code arduino timer

first time i use mikroC make program for Timer

void main()
{
unsigned char clock[9];

int i,i1,y;

TRISB = 0x00;
TRISC = 0x00;
PORTC = 0x00;
TRISA = 0xFF;
ADCON1 = 0x07; //inputs are set to digital

Lcd_Init(&PORTB);
Lcd_Cmd(LCD_CURSOR_OFF);
Lcd_Cmd(LCD_CLEAR);

T0CON=0x05;
TMR0H=0xC2;
TMR0L=0xF7;
INTCON.TMR0IF=0; //clear tmr0 overflow bit
T0CON.TMR0ON=1; //Start timer0

while(1)
{

Lcd_Chr(1,7,clock[7]+48);
Lcd_Chr(1,8,clock[6]+48);
Lcd_Chr(1,9,clock[5]+48);
Lcd_Chr(1,10,clock[4]+48);
Lcd_Chr(1,11,':');
Lcd_Chr(1,12,clock[3]+48);
Lcd_Chr(1,13,clock[2]+48);
Lcd_Chr(1,14,':');
Lcd_Chr(1,15,clock[1]+48);
Lcd_Chr(1,16,clock[0]+48);

while(!INTCON.TMR0IF);
T0CON.TMR0ON=0;

clock[0]++;

.....

if(clock[0]>9)

{

clock[1]++;
clock[0] = 0;

}

if(clock[1] >5)
{
clock[2]++;
clock[1]=0;
}

if(clock[2]>9)
{
clock[2]=0;
clock[3]++;
}
if(clock[3]>5)
{
clock[3]=0;
clock[4]++;
}
if(clock[4]>9)
{
clock[4]=0;
clock[5]++;
}
if(clock[5]>9)
{
clock[5]=0;
clock[6]++;
}
if(clock[6]>9)
{
clock[6]=0;
clock[7]++;
}

if(clock[6]==3&&clock[7]>3) // return to start
{
clock[6]=0;
clock[7]=0;
}

for count

but I don't know how to code to arduino
such as : Lcd_Chr(1,9,clock[5]+48); How to write command to arduino

Could you tell me please Thank you.

The Arduino IDE contains examples how to use the LCD library, "File/Examples/LiquidCrystal".

If you want to write the code yourself, you could use the digitalWrite() function to toggle the select/enable/data lines.
