+# GD32303E-EVAL #
+
+## 1. 简介
+
+[GD32303E-EVAL](http://gd32mcu.21ic.com/site)是兆易科技提供的开发板,使用 GD32F303ZET6 作为主控制器。提供包括扩展引脚在内的及 SWD, Reset, Boot, User button key, LED, CAN, I2C, I2S, USART, RTC, LCD, SPI, ADC, DAC, EXMC, CTC, SDIO,USBD, GD-Link 等外设资源。
+
+板载主要资源如下:
+
+| 硬件 | 描述 |
+| -- | -- |
+|CPU| Cortex-M4|
+|主频| 120MHz |
+|SRAM| 64KB |
+|Flash| 512KB |
+
+## 2. 编译说明
+
+GD32303E-EVAL板级包支持MDK5和IAR。
+| IDE/编译器 | 已测试版本 |
+| ---------- | ---------------------------- |
+| MDK5 | MDK5.25 |
+| IAR | IAR8.20 |
+
+## 3. 烧写及执行
+
+供电方式:开发板使用 Mini USB 接口或者 DC-005 连接器提供 5V 电源。
+
+下载程序:下载程序到开发板需要一套 JLink 或者使用 GD-Link 工具。
+
+串口连接:可使用USB转串口线连接开发板串口0的PA9和PA10引脚。
+
+解决IDE "Missing Device(s)"问题"
+* MDK5: 安装GigaDevice.GD32F30x_AddOn.1.0.1.exe,在 Folder Selection 中的 Destination Folder 那一栏选择 Keil uVision5 软件的安装目录,如 C:\Keil_v5,然后在 Option for Target 的 Device 选择对应的器件,同时在 Option forTarget 的 C/C++中添加路径 C:\Keil_v5\ARM\Pack\ARM\CMSIS\4.2.0\CMSIS\Include。
+
+* IAR:安装 IAR_GD32F30x_ADDON.1.0.0.exe
+
+### 3.1 配置和仿真
+
+工程已经默认使能了RT-Thread UART驱动、GPIO驱动、SPI驱动、I2C驱动。若想进一步配置工程请
+使用ENV工具。
+
+### 3.2 运行结果
+
+打开MDK或者IAR工程,进入仿真后全速运行,将会在终端设备putty上看到RT-Thread的启动logo信息:
+
+```
+ \ | /
+- RT - Thread Operating System
+ / | \ 3.0.3 build Apr 26 2018
+ 2006 - 2018 Copyright by rt-thread team
+msh />
+
+```
+
+## 4. 驱动支持情况及计划
+
+| 驱动 | 支持情况 | 备注 |
+| ------ | ---- | :------: |
+| UART | 支持 | UART0/1/2/3/4 |
+| GPIO | 支持 | |
+| SPI | 支持 | SPI0/1/2 |
+| I2C | 支持 | I2C0/1|
+
+### 4.1 IO在板级支持包中的映射情况
+
+| IO号 | 板级包中的定义 |
+| -- | -- |
+| PA9 | USART0 TX |
+| PA10 | USART0 RX |
+| PA2 | USART1 TX |
+| PA3 | USART1 RX |
+| PA5| SPI0 SCK |
+| PA6 | SPI0 MISO |
+| PA6 | SPI0 MOSI |
+| PB13| SPI1 SCK |
+| PB14 | SPI1 MISO |
+| PB15 | SPI1 MOSI |
+| PB6| I2C0 SCL |
