Recently switched to
Trying to do a quick project with (Wemos) Lolin s2 Mini
Having problems with libraries wanting to use USBSerial and not finding it. In fact, just including arduino.h throws these errors.
platformio:
Code:
sdkconfig includes
Output...
And to prove the point... this code:
throws similar errors...
Somebody mess up arduino.h for this chip??
