STM32 FSMC 驱动ILI9486L TFT无法刷屏

只看该作者 · 2013-5-11 13:05

我在红牛开发板的ILI9320 TFT驱动的基础上改的这个ILI9486L 3.5寸480*320的TFT 使用的是FSMC驱动，现在可以读出ID，向一些状态寄存器里写数据，在另外的读状态寄存器可以正确读出我写入的数据，但是为什么不能刷屏，初始化完后，屏幕没有变化，一直是白色
请大神指导啊，非常感谢

应该是设置坐标的函数有问题

void LCD_Clear(uint16_t Color)
{
  uint32_t index = 0;

  LCD_SetCursor(0,0); //320*480
  LCD_WR_REG(0x2C); /*¿ªÊ¼Ð´GRAM */
  for(index = 0; index < (320*480); index++)
  {
LCD_WR_DATA(Color);
  }
}

坐标函数的问题我是这么理解的不知道诸位的意思

你好，我最近也在驱动ILI9486L ，可是初始化一直不成功。能否把你的ILI9486的代码上传给我参考一下？谢谢

这个我试过可以显示
