B1 on-board closed loop surfaced a byte-level console interleave: before the console writer (defaultTask) registers, con_append() routes to dbg_console_write_raw() -> con_tx_bounded(), which is register-level polling with no mutual exclusion. adcTask logged every 1 ms, so its first-frame line collided with defaultTask's [NAND_FTL] init line and the required marker spanned two interleaved lines -> false FAIL. - console_log: add dbg_console_writer_ready() (returns s_con_writer_up) - adc_task: gate first-frame and 10 s stats logs on writer readiness; defer the first-frame report until the writer is up - docs: close B1/P1-1 in the registry; flip stale "remaining @test" notes; correct the console doc's obsolete "drop-only, no interleave" claim (that held for HAL gState, not register-level raw send) Bench (run_boot_test.py): VERDICT PASS, readback OK. adcTask frames/seq +10000 per 10 s = 1000 Hz, idle=0, frst_err=0; stack 496/2048 (75%). @build 0/0.

* 模块名称:ADC Sampling Task
|
||
* 模块功能:TPAFE5160 8 通道同步采样——1ms 采样节拍 + 原子快照消费 + 帧统计
|
||
* 状态说明:**B1 已落地(2026-10-10)**——本任务从空桩转为真实消费者:
|
||
* 每 1ms 触发一次 CONVST,用 tpafe5160_snapshot() 原子取数(AGENTS 铁律),
|
||
* 统计帧数/无新帧次数,并纳入看门狗 required_mask(TASK_WD_ADC)。
|
||
* ⚠ B1 阶段用**任务周期软触发**(osDelayUntil)产生采样节拍,满足 L1-1
|
||
* 判据(BUSY 连续脉冲 + frame_seq 持续递增);**精确 1 kHz / 等周波调频**
|
||
* 的硬件定时器触发为后续(需 CubeMX 加 TIM)。
|
||
* V0.1 上只有 TPAFE 三路(UA/UN/IA)测量有效;本任务只取数,不做保护运算。
|
||
* 接入前必读:取数只用 tpafe5160_snapshot()(临界区原子快照,仅任务上下文;
|
||
* 旧的 get_buf/data_ready/clear_ready 已删除);接消费者前的强制门禁
|
||
* 见根 AGENTS.md「接 ADC / RS-485 消费者前的强制门禁」+ 建任务前后各跑
|
||
* scripts/stack_report.py 做栈预算。
|
||
* 适用平台:STM32F407ZGTx + TPAFE5160
|
||
* 作者:王建锋
|
||
* 创建日期:2026-07-19
|
||
* 修改记录:
|
||
* v1.0 2026-07-19 王建锋 创建初始版本
|
||
* v1.1 2026-10-05 王建锋 P3-11:注明"预留桩(未启用)",避免误认为已实现
|
||
* v2.0 2026-10-10 王建锋 B1:实现真实消费者(1ms 节拍 + 原子快照 + 帧统计 +
|
||
* 看门狗心跳),由 Src/freertos.c 创建为 adcTask
|
||
* v2.1 2026-10-10 王建锋 日志门控:首帧/周期统计仅在 dbg_console_writer_ready()
|
||
* 为真后落日志。写者未注册时控制台走无锁直发,与
|
||
* defaultTask 的存储初始化日志字节级交错(台架实测);
|
||
* 就绪前挂起上报,就绪后补报最近一帧。
