我正在尝试使用 MI0283QT-17CP1 2.8' TFT LCD 和 ILI9341V 驱动程序，使用串行 8080 8 位数据协议。这是我的初始化代码：

LCD_Send_Command(ILI9341_DISPLAY_ON);
LCD_Send_Command(ILI9341_GRAM);

我正在尝试开始以红色（5-6-5 RGB 格式）绘制所有屏幕，但似乎无法绘制任何东西...我已经检查了所有硬件行，例如重置、CS、数据/命令和所有数据线。是否有人使用此设置并可以告诉我我做错了什么？谢谢， 阿夫纳

好的，所以我找到了答案，不是在初始化代码中，而是在屏幕的着色中。忘记添加将数据写入屏幕 sram 的 Gram 命令。所以现在我的着色功能是这样的：

    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);

        }
}

我希望这对其他人有帮助。
