+# IoT通讯协议 之 GPIO
+
+本节规定了GPIO的交互内容
+
+## 1、查询
+
+```json5
+{
+  "module": "gpio",
+  "command": "list",
+}
+```
+
+
+查询反馈
+
+```json5
+{
+  "result": "ok/fail",  //结果
+  "reason": "密码错误",  //错误原因
+  "data": [
+    {
+      "path": "/dev/gpio0",
+      "name": "开关1",
+      "type": "io", //io, adc 
+      "value": 1,
+      "writable": true,
+    },
+  ]
+}
+```
+
+
+## 2、设置GPIO
+
+```json5
+{
+  "module": "gpio",
+  "command": "write",
+  "data": {
+    "path": "/dev/gpio0",
+    "value": 1
+  }
+}
+```
+
+
+##  3、读GPIO
+```json5
+{
+  "module": "gpio",
+  "command": "read",
+  "data": {
+    "path": "/dev/gpio0",
+  }
+}
+```
+
+响应
+```json5
+{
+  "path": "/dev/gpio0",
+  "value": 1,
+}
+```
+
+## 4、GPIO数据上报
+
+```json5
+{
+  "module": "gpio",
+  "command": "status",
+  "data": [
+    {
+      "path": "/dev/gpio0",
+      "value": 1
+    },
+  ]
+}
