PIC18F I2C Communication with Arduino

[picmilan]

I am using PIC18F2450 which doesn't have hardware I2C pins.Isn't I2CWRITE just a software solution and not using actual hardware?

here is arduino code:

#include <Wire.h>

void setup() {
  Wire.begin(0x26);                // join i2c bus with address
  Wire.onReceive(receiveEvent); 
  Serial.begin(9600);          
  
}

void loop() {
 delay(1000);

}


void receiveEvent(int howMany) {

  while (1 < Wire.available()) { 
    char c = Wire.read(); 
    Serial.print(c);    
  }
  int x = Wire.read();   
  Serial.println(x);
}
