This is my first attempt to use PlatformIO to develop code for ESP32 with the Arduino framework.
Compared to the Arduino IDE, the big benefits are the total control of the build, the possibility to declare dependencies (and pin a specific version).
Requires:
- ESP32 (in my case a esp32doit-devkit-v1)
- A DHT11 sensor (with board)
- A 16x2 LCD Display with I2C driver PCF8574
- Subscribe to the free tier of OpenWeathermap API
To pass the Wifi SSID and password and the Openweather API key, you can edit the platformio.ini file ([common] section) as those values are set as build flags.
