UART as parameter to a method

Projects Programming
21

That was the constructor:

		SerialNode(HardwareSerial & UART = Serial) : thisSerial (UART){}

See the braces? That is an empty function.

22

Alright, that makes sense. So is it possible to still break that out?
Somethin like

SerialNode(HardwareSerial & UART = Serial) : thisSerial (UART);

and then

SerialNode::SerialNode(HardwareSerial & UART){

}
23

Sure. Remove the function body and the initialization list from the class definition, eg.

class SerialNode{
	public:
		SerialNode(HardwareSerial & UART = Serial);
...

Now put the initialization into the function:

SerialNode::SerialNode(HardwareSerial & UART) : thisSerial (UART)
  {
    // whatever
  }

Great! Thanks very much for your help.
