I'm trying to do a RS-485 communication between two Arduino's, implementing Max 450. However, the Arduino Zero is 48 Mhz and when I use it, I keep getting this error. Can some please help?
C:\Program Files (x86)\Arduino\libraries\NewSoftSerial\NewSoftSerial.cpp:43:24: fatal error: WConstants.h: No such file or directory
