大家好，最近的项目用到ILI9488这个芯片的屏幕，用51单片机的IO口模拟SPI信号，发送初始化代码
设置成DPI-18bitRGB模式。并用LT768芯片来显示图片。下面是程序和ILI9488资料分享：
显示图片为18bitR6G6B6信号，由于便于测试，每种颜色的6根脚都接一起了，效果如下图：




单片机驱动ILI9488源程序如下:

#define CS P13

#define CLK P14

#define DCX P15

#define SI P16

#define LCD_nRESET P00

void SPId_Init(void)

{

P1M0 |= (1<<3);

P1M1 &= ~(1<<3);

P1M0 |= (1<<4);

P1M1 &= ~(1<<4);

P1M0 |= (1<<5);

P1M1 &= ~(1<<5);

P1M0 |= (1<<6);

P1M1 &= ~(1<<6);

CS = 1;

CLK = 1;

SI = 1;

DCX = 1;

}

{
