There is no error in your file It compiles as it was and there is only a warning
Code C - [expand]
1
2
3
4

Warning at file ../main.c line 16 column : (1090) variable "_digit1" is not used, I think your Ram variables got over flow in Lite mode compilation put [B]const[/B] keyword
 
const int Lcd[]
const int convert[]

they will work fine......

- - - Updated - - -

And I atttached the compiled hex file in hitech pro mode...

hi brother
i got same error when used const
const int convert[16]='0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F';
const int lcd[16]=0x00,0x08,0x10,0x18,0x20,0x28,0x30,0x38,0x40,0x48,0x50,0x58,0x60,0x68,0x70,0x78;

whats the reason ??
 

you can activate free 45 day trial of "HI-TECH C Compiler for PIC10/12/16 MCUs" by downloading and installing it..

**broken link removed**
 

please explain these piece of code which is used to send numeric datas through usart
Code: 
#define SEND_SER(data) TXREG=data;while(!TRMT);
//


void SEND_time(unsigned int val)
{
	unsigned int a[10] = {0},cnt=1;
	unsigned int temp = val;
	if(!val)
	{
		cnt++;
	}
	while(val)
	{
		a[cnt++] = val%10;
		val = val/10;
	}
	if(temp>10)
	{
		cnt--;	
	}	
	while(cnt)
	{
		SEND_SER(a[cnt--]+'0');
	}	
}
 

hello,

To reduce amount of used ram
instead of integer you can use unsigned char table , because size of data is one byte.

unsigned char convert[16]='0','1','2','3','4','5','6','7','8','9','A','B','C','D','E','F';
unsigned char lcd[16]=0x00,0x08,0x10,0x18,0x20,0x28,0x30,0x38,0x40,0x48,0x50,0x58,0x60,0x68,0x70,0x78;


and you get error because you want to put a int inside a byte
TXREG=(lat[0]);
TXREG is a register (1 byte)
lat[0] is 4 bytes

or use cast
TXREG=(unsigned char) lat[0];
but i think it is not what do you want ..
