SoftwareSerial.h incompatible with PinChangeInt.h in 1.0 #7

Closed GoogleCodeExporter closed 9 years ago

GoogleCodeExporter commented 9 years ago
Including both SoftwareSerial and PinChangeInt libraries such as the following 
will result in compile errors while commenting out one or the other will not:

#include SoftwareSerial.h
#include PinChangeInt.h
#include Adaencoder.h

void setup()  
{

}

void loop() 
{
}

SoftwareSerial uses Pin Change Interrupts, and as a result it is indeed in 
direct conflict with this library.

The only way to make them compatible would be to do something like this:

* Figure out which port(s) you want to use for Software Serial.
* Figure out which port(s) you want to use for Pin Change Interrupts.

Set up the #defines in Pin Change Interrupts so as to shut off the Software 
Serial ports:  #define NO_PORTx_PINCHANGES

Copy the SoftwareSerial library to your personal libraries folder; call it 
mySoftwareSerial or something like this.  Do a global namechange from 
SoftwareSerial to mySoftwareSerial.

Delete the appropriate ISR in mySoftwareSerial.  For example, if you knew you 
weren't going to use PORTD for SoftwareSerial, you would delete:

#if defined(PCINT2_vect)
ISR(PCINT2_vect)
{
  SoftwareSerial::handle_interrupt();
}
#endif 

and so on.

So this is a limitation, not a bug.

I have tried to implement this by adding ...

1)#define NO_PORTD_PINCHANGES (in my sketch)
2)and deleting:
#if defined(PCINT2_vect)
ISR(PCINT2_vect)
{
  SoftwareSerial::handle_interrupt();
}

#endif 

I did not decide to rename the SoftwareSerial library contents as i do not know 
how to do a global namechange. I need two serial ports and 5 external 
interrupts, can you please advise me on what to do?

Yes, you have to change the name of the .h file, the .cpp file, put them in 
your directory alongside your sketch, and #include it under the new name. Then 
it should work.
