PlatformIOで、一度作ったプロジェクトを他のM5Stackモジュールで動かそうとしたときに、platformio.iniに記載するお決まりの記載をメモとして残しておきます。
また、Defineマクロも一緒に設定されるので、活用しましょう。

ESP32用のコードをESP8266で動かすときの注意点

〇ESP32

#include <WiFi.h>
#include <HTTPClient.h>

HTTPClient http;
http.begin(p_url);

〇ESP8266

#include <ESP8266WiFi.h>
#include <ESP8266HTTPClient.h>

HTTPClient http;
WiFiClient client;
http.begin(client, p_url);
