折腾了几日，总算能够将图片显现在LCD上了，我运用的东华的WXCAT35-TG3#001 TFT LCD。首要运用PHOTOSHOP软件将图片改成宽320，高240，留意不要反了。然后用Image2Lcd_32软件提取出数组。我选的是24位真彩。所以一个像素3个字节，显现的时分，通过位运算将3个字节合到一同，显现在一个像素上。
Image2Lcd_32的装备办法：
#include “2440addr.h”
#include “picture.h”
//笔直同步信号的脉宽、后肩和前肩
#define VSPW 15
#define VBPD 3
#define VFPD 5
//水平同步信号的脉宽、后肩和前肩
#define HSPW 8
#define HBPD 58
#define HFPD 15
#define CLKVAL 10
#define HOZVAL 319
#define LINEVAL 239
#define PWREN 1
#define MMODE 0
#define PNRMODE 3
#define BPPMODE 13
#define INVVCLK 0
#define INVVD 0
#define INVVDEN 0
#define U32 unsigned int
