我试图使用MI0283QT-17CP1.2.8‘液晶显示与ILI9341V驱动使用串行8080 8位数据协议。这是我的初始化代码：

好的，所以我找到了答案，它不是在初始化代码中，而是在屏幕的着色中。忘记添加一个Gram命令，将数据写入屏幕sram。所以现在我的着色函数是这样的：
void LCD_MNG_FillRect(uint16_t Xpos, uint16_t Ypos, uint16_t Width, uint16_t Heigth, LCD_COLORS_NAMES Color)
{
uint32_t Index;
uint16_t DisplayColor;
uint32_t Size = (uint32_t)(Width * Heigth);
LCD_InitDrawImage(Xpos, Ypos, Width, Heigth);
DisplayColor = LCD_MNG_CreateColor565((uint8_t)LCD_ColorsList[(int)Color].Red, (uint8_t)LCD_ColorsList[(int)Color].Green, (uint8_t)LCD_ColorsList[(int)Color].Blue);
LCD_Send_Command(ILI9341_GRAM); // this was missing...
for (Index = 0; Index < Size; Index++)
{
LCD_DisplayNextPoint(DisplayColor);
}
}我希望这会对其他人有所帮助。
