 ## UART
 
-- 添加一个 UART 端口外设配置
+如何添加一个 UART 端口外设配置？
+
+1. 选择 Stacks 配置页，点击 New Stack 找到 UART。
 
 ![image.png](picture/rascuart.png)
 
+2. 配置 UART 参数，因为需要适配 RT-Thread 驱动中使用的命名，所以需要修改命名，设置 **name** 、**channel**  、**callback** 是一致的标号。

+  2. 打开 ICU 中断通道 IRQ4
+

+  3. 创建 stack 并进入配置。因为需要适配 RT-Thread 驱动中使用的命名，所以需要修改命名，设置 **name** 、**channel**  、**callback** 是一致的标号。选择你希望的触发方式。最后保存配置，生成配置代码。

+

+   
+   void irq_callback_test(void *args)

+       rt_err_t err = rt_pin_attach_irq(pin, PIN_IRQ_MODE_RISING, irq_callback_test, RT_NULL);
+       if(RT_EOK != err)

+## WDT
+
+1. 创建 WDT 
+
+![image-20211019152302939](picture/wdt.png)
+
+2. 配置 WDT，需要注意在 RT-Thread 中只是用了一个 WDT 设备，所以没有对其进行编号，如果是新创建的 WDT 设备需要注意 name 字段，在驱动中默认使用的是 `g_wdt` 。
