* debug_task.c - USB 虚拟串口(CDC)姿态输出(欧拉角 + 姿态链路诊断)
|
|
* 每 DEBUG_OUT_PERIOD_MS 输出一行。单位: 角度 ° / 加速度 m/s² / 角速度 rad/s
|
|
*
|
|
* ---- 欧拉角(QuaternionEKF 解算结果,见 modules/ins) ----
|
|
* yaw 多圈连续偏航角 (att_deg_yaw = INS.YawTotalAngle,云台 Yaw 环反馈)
|
|
* pitch 绕 y 轴角 (att_deg_pitch = QEKF_INS.Roll )
|
|
* roll 绕 x 轴角 (att_deg_roll = QEKF_INS.Pitch,云台 Pitch 环反馈)
|
|
* QEKF 内部 Pitch/Roll 命名与航空惯例互换,映射与原因见 attitude.c 文件头。
|
|
* 注意 yaw 无绝对基准(纯陀螺积分),上电静止时恒为该次上电的相对 0 点。
|
|
*
|
|
* ---- 健康位 / 诊断位(排查"角度不动或自漂"时必须一起看) ----
|
|
* cvg 1-INS.ConvergeFlag:EKF 卡方检验通过、姿态可信(与原诊断输出同义,
|
|
* 不要改成别的量,否则会丢掉"是否真的收敛"这一唯一判据)
|
|
* rdy 1-att_ready:ins_update() 至少执行过一次,只说明"在跑",不代表可信
|
|
* imu 1-bmi088_online:IMU 初始化成功;0=ID 检测失败,姿态必然全 0
|
|
* an |bmi088_accel|:静止时≈9.8;≈0 说明 IMU 根本没给出数据
|
|
* gn |bmi088_gyro|:原始陀螺模长(**未减零偏**),静止时≈0
|
|
* gx/gy/gz 原始陀螺三分量(rad/s) —— 与 gn 一起可判断数据是否冻结
|
|
* zo ins_gyro_z_offset:上电静止标定得到的 z 零偏(rad/s)。**关键**:
|
|
* 实际进入滤波器的 gyro_z = gz - zo。若 zo 与 gz 量级相近甚至更大,
|
|
* 而 yaw 又匀速自漂,即标定窗口内车体在动把零偏标歪了
|
|
* ck ins_z_cal_ok:1-标定时全程静止,zo 可信;0-三轮都在动,zo 存疑
|
|
* ca/cg 加速度/陀螺采样计数:停止增长即数据路已死(数值冻结时它们不涨)
|
|
* se bmi088_spi_errors:SPI/DMA 出错次数;st=bmi088_spi_state()
|
|
* (1=READY,非 1 说明 SPI 被卡住,数据路会因此停摆)
|
|
*
|
|
* 开关: DEBUG_ATT_HEALTH=0 只输出三个欧拉角;DEBUG_ATT_DIAG=0 去掉诊断位。
