* 外接唤醒模组的支持，可以有多种自定义唤醒词，进行唤醒小智 ESP32(非C3，非S3) 面包板上已支持 * Update application.cc 外接唤醒模组的支持，好处是可以有多种自定义唤醒词，进行唤醒小智 唤醒模组需要一个GPIO Pin，设置成输出模式+高电平 对该Pin进行唤醒设置，1秒内的低电平脉冲，也就是小智的一个Click 可以参考 ESP32 面包板中的 asr_button_ 按钮的功能函数调用 本人测试采用ASR-ProV1.0版本的唤醒模组，测试内容包括：自定义唤醒词，唤醒词打断，唤醒词回应 此代码兼容其他型号的唤醒模组，并没做限制模组型号，方便大家使用 Modify By MarsBear * Update esp32_bread_board.cc --------- Co-authored-by: Xiaoxia <terrence@tenclass.com>
