-CSK6002 kscan
-################
+简介
+=====================
+演示如何使用 Zephyr 的按键扫描 (kscan) API 与模拟按键进行交互。运行该代码后，按键扫描事件将被打印到控制台。
 
-Overview
-********
+构建步骤
+=====================
+lisa zep build -b csk6_duomotai_devkit ./samples/driver/keysense/ -p
 
+功能说明
+=====================
+1. 从设备树中定义的 keysense 节点获取 kscan 设备的配置信息
 
+::
 
+    const struct device *kscan_dev = DEVICE_DT_GET(DT_NODELABEL(keysense));
 
+2. 检查 kscan 设备是否就绪
+
+::
+
+	if (!device_is_ready(kscan_dev)) {
+		printk("kscan device  not ready \n");
+		return -1;
+	}
+
+3. 配置 kscan 设备的回调函数
+
+::
+
+	ret = kscan_config(kscan_dev, kb_callback);
+
+4. 回调函数打印按键事件的行列号和按键状态
+
+::
+
+    static void kb_callback(const struct device *dev, uint32_t row, uint32_t col, bool pressed)
+    {
+        ARG_UNUSED(dev);
+
+        printk("Key row = %d col = %d Pressed = %u\n", row, col, pressed);
+    }
+
+运行
+======================
+按下开发板复位按钮，运行程序。给定 PB05 输入电压，在控制台中可以看到按键扫描事件的打印信息。
