Hi andatche
I try to compile your HelloWorld project with Visual Studio Code + Platformio and I have this error messages (see bellow).
My target board is a ESP8266 ESP-12E ( LoLin NodeMCU_esp8266_001), and I have this error messages (see bellow).
You package and the documentation is well done and you did a great job. Peraphs I am missing a point or your code is not compliant with the latest environment (need an update ?).
