+## 开发板介绍
+
+MAX32660-EVSYS是美信官方的开发板，搭载MAX32660芯片，基于ARM Cortex-M4F内核，最高主频96MHz，具有丰富的外设资源，内核带有FPU。
+
+开发板外观如下图所示
+
+![](doc/images/board.jpg)
+
+MAX32660-EVSYS开发板常用 **板载资源** 如下：
+
+- MCU：MAX32660
+- 板载设
+  - LED：1个，GPIO P0_13 ，高电平点亮，低电平灭 。
+  - 按键：1个，GPIO P0_12,   按下低电平，松开高电平。
+- 调试接口：板载CMSIS-DAP调试器。
+
+## 外设支持
+
+本 BSP 目前对外设的支持情况如下：
+
+| **片上外设** | **支持情况** |       **备注**        |
+| :----------- | :----------: | :-------------------: |
+| GPIO         |              |                       |

+
+### 进阶使用
+
+此 BSP 默认只开启了串口 的功能，更多高级功能需要利用 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。
+
+4. 输入`scons --target=mdk4/mdk5/iar` 命令重新生成工程。
+
