Hello World! Web Server

Platform.IO IDE

Both ESP32 and ESP8266 are supported Web Server use me-no-dev/ESPAsyncWebServer Platform.io will check dependecy and download dependency libraries automatically. Tool bar at bottom , click Switch env icon to select Project and env

For ESP32

*env:esp32dev (01_esp32_Hello) folder*

For ESP8266

*env:nodemcuv3 (01_esp32_Hello) folder*

Edit platform.ini.

Select esp32 and nodemcu environment You also can compiler both, platform.io will select right code and Serial to download, it takes longer.

For ESP32

[platformio]
default_envs = esp32dev
; default_envs = nodemcuv3

For ESP8266

[platformio]
; default_envs = esp32dev
default_envs = nodemcuv3

We also define lib_extra_dirs in platform.ini , then platform.io will search this path. It is located in 00_esp32_littlefs/lib folder

lib_extra_dirs = ../00_esp32_littlefs/lib

In main.cpp, include these files which will be used.

  #include <Arduino.h> 
  #include "debuglog.h" // log print
  #include "ledpwm.h"   // esp32 pin 2 can use pwm mode, ESP8266 cannot.
  #include "WebServer.h" // i.e. ESPAsyncWebServer include...

config WIFI MODE in winit.cpp if STA modified SSID PASS in WiFiInit, the Server dispatchs some HTTP_GET and respones.

// 1. *** modified your SSID, PASSWORD pair 
  if (!WiFiInit(WIFI_STA_AUTO_MODE,"****", "********")) {
      Serial.println("Error:Wifi fail");
      return ;
  } 
// 2, start up Web Server
  WebServerHello();
