i2c scanner example

would be great to have

That's a great suggestion. I'll see about getting something out later this week.
If you need something right now, I think (but haven't tested), you should be able to do:

#include "SoftI2CMaster"
SoftI2CMaster i2c = SoftI2CMaster( 4,5, true );

for( int i=1; i<125; i++ ) {
  int rc = i2c.beginTransmission( i );
  i2c.endTransmission(i);
  if( rc == 0 ) {
    Serial.print("device at address:"); Serial.println(i);
  }
}

On SoftwareWire, the lib that you found on Arduino Library Manager (started by a fork of this lib) is it possible use the standard i2c scanner sketch. The sketch is integrated in the example also.

@Testato Aware of that - but thanks :)
@todbot Thanks for the quick help.

This (small correction) does indeed work:

#include "SoftI2CMaster"
SoftI2CMaster i2c = SoftI2CMaster( 4,5, true );

for( int i=1; i<125; i++ ) {
  int rc = i2c.beginTransmission( i );
  i2c.endTransmission();
  if( rc == 0 ) {
    Serial.print("device at address:"); Serial.println(i);
  }
}

oops, yeah that's what I meant. :)
