Re: Error Compiling Morserino

Willi, OE1WKL


Not really sure what’s going on here. Try to comment out line 133 in the source - as th4 definition is the same in your version of the library, this should not be a problem.

Removing the libraries just removes the warning.  I t does not make any change in the conflict.

This report would have more information with
"Show verbose output during compilation"
option enabled in File -> Preferences.

The package from Heltec has include a definition of Vext.  I have tried it with expressif package and the result is the same. 

I have chosen the WiFi LoRa 32(V2) as the board.  This includes file pins_arduino.h which has the declaration for Vext which conflicts with your declaration.
