+# io_device_control
+
+`io_device_control` 组件用于统一管理项目中的简单 IO 外设控制。
+
+当前定义：
+
+- `GPIO1`：水泵控制（高电平有效）
+- `GPIO0`：光照控制（高电平有效）
+
+## 对外接口
+
+头文件：`include/io_device_control.h`
+
+- `esp_err_t io_device_control_init(void);`
+  - 初始化 GPIO 输出方向，并将水泵与光照默认置为关闭（低电平）。
+- `esp_err_t io_device_control_set_pump(bool on);`
+  - 控制水泵开关，`true` 为开，`false` 为关。
+- `esp_err_t io_device_control_set_light(bool on);`
+  - 控制光照开关，`true` 为开，`false` 为关。
+
+## 使用方式
+
+在 `app_main` 中先初始化，后续在业务逻辑中按需调用控制接口。
+
+```c
+#include "esp_check.h"
+#include "io_device_control.h"
+
+void app_main(void)
+{
+    ESP_ERROR_CHECK(io_device_control_init());
+
+    // 后续按需调用
+    // ESP_ERROR_CHECK(io_device_control_set_pump(true));
+    // ESP_ERROR_CHECK(io_device_control_set_light(true));
+}
+```
+
+## 注意事项
+
+- 控制接口在未初始化时会返回 `ESP_ERR_INVALID_STATE`。
+- 若硬件驱动电路为反相，请在硬件层或组件内部统一处理，不建议在业务层散落取反逻辑。
