#include "lcd_kbd1.c"
#include <string.h>
#fuses XT,NOWDT
#use delay(clock=4000000) //one instruction=1us
#use rs232(baud=9600, xmit=PIN_C6, rcv=PIN_C7)
void main()
{
LCD_Init ( );

static char RX[30], string1[30], string0[30], ptr ;
static int1 jj;
static int8 i;
#int_rda
void serial_isr() {
RX[i++]=getch();
strcpy(string1,RX);
jj=1;
}
void main() {
enable_interrupts(GLOBAL);
enable_interrupts(INT_RDA);
jj=0;
LCD_Init ( );
if(jj==1) {
LCD_PutCmd ( CLEAR_DISP );
LCD_SetPosition ( LINE_16_1);
printf(LCD_PutChar,string1);
jj=0;
}//IF
}//MAIN
