Possible to use Wire and SoftwareSerial together?

Hi,

When I use Wire and SoftwareSerial together things stop working (Duemilanove). I need to use the regular HW UART for comms with my PC, and therefore use SoftwareSerial to drive a Pololu servo serial microcontroller, and the Wire interface to get readings from a compass. Is it possible to use the Wire and SoftwareSerial together?

The setup code looks like this:

#include <SoftwareSerial.h>
#include <Wire.h>

#define rxPin 8
#define txPin 7

// HMC6352 compass
int addr = 0x42 >> 1;
int heading = 0;
// Servo
unsigned int pos = 3000;
SoftwareSerial swserial = SoftwareSerial(rxPin, txPin);

void setup()
{
    Serial.begin(9600);
    Wire.begin();

    pinMode(48, OUTPUT);
    digitalWrite(48, HIGH);
    heading = 0;

    // Servo
    pinMode(rxPin, INPUT);
    // Keep Pololu board from getting spurious signal
    digitalWrite(txPin, HIGH);
    pinMode(txPin, OUTPUT);
    swserial.begin(9600);
    Serial.flush();
}

If I comment this line out, then the Wire interface works.

//SoftwareSerial swserial = SoftwareSerial(rxPin, txPin);

Else the Wire interface doesn't work.

Any suggestions would be appreciated
Thanks

SoftwareSerial is obsolete, and has been for years. You should try NewSoftSerial, instead.

Thanks very much for the help, that solved my problem
