I have a Dragino Yun Shield connected with an Arduino Mega.
I would like to utilize Serial1, Serial2, and Serial3.
Whenever I try to begin a serial port [eg. - Serial2.begin(9600);], I get " no matching function for call to 'HardwareSerial::begin()' ".
If not, are there other options for receiving serial communications? I tried softwareserial, and AltSoftSerial with no luck.
Any help is greatly appreciated.
Edit - Apparently I forgot the baud rate in my begin statement. Carry on, as you were, nothing to see here, I'm going to bed!
