Hi,
Is it possible to setup SoftwareSerial as:
SoftwareSerial mySerial(3,2);
I have a phototransistor reading IrDA data and when read on PD5 I get valid data.
When connected to INT1, I get data, but it is not valid.
Given that Rx is now on INT1, would I have to disable the interrupt and set the port as something else.
Unfortunately, I cannot change this and must use INT1 as the SoftwareSerial Rx.
Any assistance would be greatly appreciated.
What?
I'm having trouble understanding your question. Yes, you can use Pin 2 and Pin 3 for SoftwareSerial. No, you can't use INT1 (Pin 3) or INT0 (Pin 2) for external interrupts when you are using those pins for SoftwareSerial. I'm not sure what you are saying about Pin 5 (PD5).
You could use any pair of pins for Software Serial and put a jumper from Rx to one of the interrupt pins.
On second thoughts I think that is the opposite of what you want.
I don't understand why you must use pins 2 and 3 for SoftwareSerial if you would prefer to use them for something else.
You may be interested in the demo yet another software serial if you want to use it as a basis for hacking. But as it is it MUST use one of the external interrupts. You could probably modify it to work with a pin change interrupt.

Many thanks.....I got it sorted.
