Схема подключения 3,5-дюймового TFT-ЖК-дисплея с mega r3

Сообщение на форуме

Я хотел бы спросить, у кого-нибудь этот щит полностью работает.

Моя самая большая проблема-это сенсорный экран, который я не смог заставить его работать.

Вот код, который я использую:

// ic: ili9327  
#define LCD_RD   A0
#define LCD_WR   A1     
#define LCD_RS   A2        
#define LCD_CS   A3       
#define LCD_REST A4

void Lcd_Writ_Bus(char VH)
{
 unsigned char i,temp,data; 
 data=VH;
 for(i=8;i<=9;i++)
 {
   temp=(data&0x01);
   if(temp)
     digitalWrite(i,HIGH);
   else
     digitalWrite(i,LOW);
   data=data>>1;
 } 
 for(i=2;i<=7;i++)
 {
   temp=(data&0x01);
   if(temp)
     digitalWrite(i,HIGH);
