# BMI270 三击检测示例 ## 概述 本示例演示了如何使用 BMI270 传感器进行三击检测。 ## 功能特点 - **三击检测**：使用 BMI270 检测三击手势 - **低功耗**：BMI270 INT 引脚触发 GPIO 中断进行硬件级三击检测，连接 RTC GPIO 可实现深度睡眠三击唤醒 - **实时处理**：低延迟的三击识别响应 ## 硬件要求 - ESP32 开发板（ESP32-S3、ESP32-C5 等） - BMI270 传感器 ## 输出示例 当检测到三击时，您应该看到如下输出： ``` I (1378) bmi270_api: BMI270 sensor created successfully I (1388) MAIN: Tap feature enabled, result: 0 I (1488) MAIN: Tap the sensor to get tap interrupt... I (6198) MAIN: Interrupt detected! I (6198) MAIN: Tap interrupt detected! I (6198) MAIN: Triple Tap Detected! I (6198) MAIN: Waiting 3 seconds before next detection... I (9198) MAIN: Ready for next tap detection... I (11008) MAIN: Interrupt detected! I (11008) MAIN: Tap interrupt detected! I (11008) MAIN: Other tap detected (not triple) I (11008) MAIN: Waiting 3 seconds before next detection... I (14018) MAIN: Ready for next tap detection... ```
