如果我尝试在图书馆中进行，则无法包含，但如果我在图书馆中进行，则效果很好main.cpp

这是树的输出（文件夹结构）

这是main.cpp

#include <Arduino.h>

#include "Microphone.h"

void setup() {
  // put your setup code here, to run once:
}

void loop() {
  // put your main code here, to run repeatedly:
}

这是lib/Microphone.h

#include <i2s.h>

这是lib/Microphone.cpp

#include "Microphone.h"

这是platformio.ini

[env:d1_mini_lite]
platform = espressif8266
board = d1_mini_lite
framework = arduino

这是我在构建时遇到的错误

我能够通过添加#include <Arduino.h>之前#include <i2s.h>解决它Microphone.h并且工作正常
