这个库默认是 uno 板子的，如果换成mega2560 可以直接插上去。
在mega2560板子下测试
#include "SPI.h"
#include "TFT_22_ILI9225.h"




#define TFT_RST A4
#define TFT_RS  A3
#define TFT_CS  A5  // SS
#define TFT_SDI A2  // MOSI
#define TFT_CLK A1  // SCK
#define TFT_LED A0   // 0 if wired to +5V directly

// Use hardware SPI (faster - on Uno: 13-SCK, 12-MISO, 11-MOSI)
//TFT_22_ILI9225 tft = TFT_22_ILI9225(TFT_RST, TFT_RS, TFT_CS, TFT_LED);
// Use software SPI (slower)
TFT_22_ILI9225 tft = TFT_22_ILI9225(TFT_RST, TFT_RS, TFT_CS, TFT_SDI, TFT_CLK, TFT_LED);
