+
+## 使用说明
+
+使用说明分为如下两个章节：
+
+- 快速上手
+  
+  本章节是为刚接触 RT-Thread 的新手准备的使用说明，遵循简单的步骤即可将 RT-Thread 操作系统运行在该开发板上，看到实验效果 。
+
+- 进阶使用
+  
+  本章节是为需要在 RT-Thread 操作系统上使用更多开发板资源的开发者准备的。通过使用 ENV 工具对 BSP 进行配置，可以开启更多板载资源，实现更多高级功能。
+
+### 快速上手
+
+本 BSP 为开发者提供 MDK5工程，支持 GCC 开发环境，也可使用RT-Thread Studio开发。下面以 MDK5 开发环境为例，介绍如何将系统运行起来。
+
+#### 硬件连接
+
+使用GD-Link调试器连接开发板到 PC，使用USB2TTL连接USART0，并给开发板供电（可使用Mini USB接口或DC-005连接器提供5V电源）。
+
+#### 编译下载
+
+双击 project.uvprojx 文件，打开 MDK5 工程，编译并下载程序到开发板。
+
+> 工程默认配置使用 GD-Link 仿真器下载程序，在通过 GD-Link 连接开发板的基础上，点击下载按钮即可下载程序到开发板
+
+#### 运行结果
+
+下载程序成功之后，系统会自动运行，LED 闪烁。
+
+连接开发板对应串口到 PC , 在终端工具里打开相应的串口（115200-8-1-N），复位设备后，可以看到 RT-Thread 的输出信息:
+
+```bash
+ \ | /
+- RT -     Thread Operating System
+ / | \     5.0.0 build Mar  3 2023 00:43:44
+ 2006 - 2022 Copyright by RT-Thread team
+msh />
+```
+
+### 进阶使用
+
+此 BSP 默认只开启了 GPIO 和 串口0的功能，如果需使用高级功能，需要利用 ENV 工具对BSP 进行配置，步骤如下：
+
+1. 在 bsp 下打开 env 工具。
+
+2. 输入`menuconfig`命令配置工程，配置好之后保存退出。
+
+3. 输入`pkgs --update`命令更新软件包。
+
+4. 输入`scons --target=mdk4/mdk5/iar` 命令重新生成工程。
+
+## 注意事项
+
+- 若需使用板载 SPI Flash，请在 `menuconfig` 中启用以下配置：
+
+```
+RT-Thread Components  --->
+  Device Drivers  --->
+    [*] Enable SPI BUS support (RT_USING_SPI)
+        [*] Enable SFUD for SPI Flash (RT_USING_SFUD)
+
+Hardware Drivers Config  --->
+  On-chip Peripheral Drivers  --->
+    [*] Enable SPI BUS (BSP_USING_SPI)
+        [*] Enable SPI5 BUS (BSP_USING_SPI5)
+```
+
+- 若需使用SDRAM功能，请在 `menuconfig` 中启用EXMC配置
+- 若需使用DCI摄像头功能，请在 `menuconfig` 中启用相应的DCI配置
+- 若需使用LCD显示功能，请在 `menuconfig` 中启用LCD相关配置

+#### 1. 简介
+
+用于 GD32F470 立创开发板配套 RGB LCD 屏幕的驱动，支持触摸。
+
+> **原作者：LCKFB**  
+> 本驱动最初由 LCKFB 开发，由 godmial 移植到本BSP。
+
+#### 2. 在 ENV 中的开启  
+ps：建议全部开启  
+```
+Hardware Drivers Config  --->
+      Board extended module Drivers --->
+                            Enable LCD --->
+                                - [*]Enable TLI
+                                - [*]Enable SDRAM
+                                - [*]Enable TOUCH
+                                - [*]Enable GPU
+                                - [*]Enable DRAW PANEL EXAMPLE
+```
+
+#### 3. 注意事项
+
+1. 如果屏幕出现刷新抖动，触摸屏出现连点的情况，可以尝试在 `libraries\GD32F4xx_Firmware_Library\CMSIS\GD\GD32F4xx\Source\system_gd32f4xx.c` 将时钟值修改为  
+   `#define __SYSTEM_CLOCK_240M_PLL_25M_HXTAL       (uint32_t)(240000000)`  
+   然后重新编译即可
+
+2. 由于代码格式审查原因，本驱动未包含中文显示函数。但可直接移植官方源码中的中文显示函数进行使用。
+
+3. 为避免 `scons` 命令编译不通过，代码使用了如下代码段以适配不同编译器：
+   ```
+   #if defined(__CC_ARM) || defined(__ARMCC_VERSION)
+   // Keil MDK
+   uint16_t ltdc_lcd_framebuf0[800][480] __attribute__((at(LCD_FRAME_BUF_ADDR)));
+   #elif defined(__GNUC__)
+   // GCC (RT-Thread)
+   uint16_t ltdc_lcd_framebuf0[10][10]; // 此行为避免 scons 编译错误而添加
+   #endif
+     
+
