Main UART code

Open the file 'SC_Tutorial.c'. Add the following declaration to near the top of the file:
#include "r_smc_entry.h"
#include "r_okaya_lcd.h"
#include "r_cg_userdefine.h"
#include "Config_S12AD0.h"
#include "r_rsk_switch.h"

static void lcd_display_adc
/* Prototype declaration for uart_display_adc */

Add the following highlighted code in the main function:
