-# TM4C129X-Development Board
-http://www.ti.com/tool/dk-tm4c129x
-
-## 1. 简介
-
-TM4C129X-DK是TI官方的开发板，此为其中一款开发板，带屏幕，配置更高。
-TI官方提供了详细的SDK支持，含USB，LWIP，甚至图形库。
-
-核心板板载主要资源如下：
-
-| 硬件 | 描述 |
-| -- | -- |
-|芯片型号| TM4C129XNCZAD |
-|CPU| ARM Cortex-M4F |
-|主频| 120MHz |
-|片内Flash| 1024B |
-|片内SRAM| 256KB |
-
-
-## 2. 编译说明
-
-TM4C129X-DK板级包目前仅支持MDK5编译器，以下是具体版本信息：
-
-| IDE/编译器 | 已测试版本                   |
-| ---------- | ---------------------------- |
-| MDK5       | MDK521a                      |
-
-
-## 3. 烧写及执行
-
-TM4C129X-DK本身提供了一个烧录接口，是Stellaris ICDI，keil本身不提供该驱动，需自行下载。
-http://www.ti.com.cn/tool/cn/stellaris_icdi_drivers
-
-供电方式：使用ICDI接口即可供电
-
-### 3.1 运行结果
-
-如果编译 & 烧写无误，当复位设备后，会在串口上看到RT-Thread的启动logo信息：
-
-```bash
- \ | /
-- RT -     Thread Operating System
- / | \     3.0.3 build Feb 28 2018
- 2006 - 2018 Copyright by rt-thread team
-finsh />
-
-```
-
-## 4. 驱动支持情况及计划
-
-| 驱动 | 支持情况  |  备注  |
-| ------ | ----  | :------:  |
-
-### 4.1 IO在板级支持包中的映射情况
-
-| IO号 | 板级包中的定义 |
