ili9481能不能像9320那样设置光标，还有自增方向；我看手册发现好像只能设置显示的矩形区域，用0x002A和0x002B命令。
但是现在写点的函数仅在设置光标时就需要写10个数据，以下是STM32的FSCM驱动设置光标的例子，其实就是设置光标到右下角之间的区域为操作区域。
*(__IO uint16_t *) (Bank1_LCD_ili9481_R) = (0x002A);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (Xpos>>8);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (0x00FF&Xpos);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (0x0001);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (0x003F);
*(__IO uint16_t *) (Bank1_LCD_ili9481_R) = (0x002B);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (Ypos>>8);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (0x00FF&Ypos);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (0x0001);
*(__IO uint16_t *) (Bank1_LCD_ili9481_D) = (0x00df);

这太慢了，9320的，只需要写四次：
*(__IO uint16_t *) (Bank1_LCD_ili9325_R) = R32;
*(__IO uint16_t *) (Bank1_LCD_ili9325_D) = Xpos;
*(__IO uint16_t *) (Bank1_LCD_ili9325_R) = R33;
*(__IO uint16_t *) (Bank1_LCD_ili9325_D) = Ypos;

在有没有办法加快写点函数？
