Arduino 32U4 problem #25

Closed DSPQPSK closed 3 years ago

DSPQPSK commented 4 years ago

Hello, sorry for disturbing you. Is it possible that there is a problem when using 32U4 processors?

I compile the Soft Serial example with the target Arduino Nano, everything is perfect. If I now switch to 32U4 based Arduino boards like Leonardo or Micro, then I get the following error:

C:\Program Files\Arduino\hardware\arduino\avr\cores\arduino/USBAPI.h:154:16: note: previous declaration as 'Serial_ Serial'

extern Serial_ Serial;

^~

exit status 1

A similar behavior could be observed if I use the HW Serial example.

Thanks for your support.

The extern HardwareSerial Serial was removed in the new version, so should be fixed now.
