* @file app_spray.c
|
||
* @brief 喷淋作业引擎：一轮 = 单次时长 × 次数 + 间隔（规格书第 10 章）
|
||
* @author cyWu <1917507415@qq.com>
|
||
* @date 2026.09.09
|
||
* @version V1.3.0
|
||
* @history
|
||
* - V1.3.0, 2026.09.09, cyWu, P2 轮来源 owner（手动/计划/联动）+ 计划参数
|
||
* 通道 + 轮结束事件（仲裁收口用）
|
||
* - V1.2.0, 2026.09.09, cyWu, P1 请求队列化：任务上下文只置请求，全部状态
|
||
* 变更收进 20ms tick 消费（DP 写路径与 ISR 竞争消除）
|
||
* - V1.1.0, 2026.09.09, cyWu, P1 增加 restart（DP7 写入中止旧轮重开）
|
||
* - V1.0.0, 2026.09.09, cyWu, P0 首次发布（默认 10s×3 次+3s，只跑一轮）
|
||
*
|
||
* @note 本模块是**唯一切泵者**（规格书 7.2）：键/DP/联动/计划都只请求
|
||
* "开一轮 / 停"。20ms 节拍倒数，禁止阻塞 delay。间隔等待也算作业态
|
||
* （DP1=1、绿灯继续闪），但泵已关、不记运行秒（app_runrec 只计
|
||
* app_pump_get()==1 的秒）。
|
||
*
|
||
* @note ⚠ 上下文模型：s_spray 状态机只允许在 20ms tick 上下文访问。
|
||
* 任务上下文（按键回调同上下文 / BLE 线程写 DP）只准调 req_* 接口
|
||
* 置单字节请求，幂等判断与执行全部延迟到 app_spray_poll 消费，
|
||
* 杜绝 ISR 抢占写到一半的状态。轮结束事件由 poll 置位、
|
||
* app_arbiter 在 500ms 任务上下文消费（单次计划自毁 / 出队 / 补判联动）。
