* @brief 水泵双脚成对控制：PC2 供 5V + PA6 导通，同开同关
|
||
* @author cyWu <1917507415@qq.com>
|
||
* @date 2026.09.09
|

* @version V1.0.0

* @history
|
||
* - V1.0.0, 2026.09.09, cyWu, P0 首次发布
|
||
*
|
||
* @note 禁止只开一只脚；上电两脚默认低、绝不自动开泵。本模块不保存"开"，
|
||
* 是否开由上层 app_spray 作业引擎决定（规格书 7.2，app_pump_set 只
|
||
* 由 app_spray 调用）。泵无过零/继电器，请求态==实际态。
