sda and slc ic2 on esp12

I’m sure this has been asked before, but I couldn’t find it on searches.

I am doing an oled1306 on esp-12 from geekcreit. I am running the scanner (which works for me on other occasions.

1306

scl → d4 (gpi02)
sda → d5 (gpio14)

nothing shows for scanner.

I have modified Wire.begin(4,5) and flipped it to (5,4)

Scanner isn’t picking anything up.

What I m missing?

#include <SPI.h>
#include <Wire.h>
void setup()
{
  Wire.begin(4,5);
 
  Serial.begin(9600);
  Serial.println("\nI2C Scanner");
}
void loop()
{
  byte error, address;
  int nDevices;
 
  Serial.println("Scanning...");
 
  nDevices = 0;
  for(address = 1; address < 127; address++ )
  {
    // The i2c_scanner uses the return value of
    // the Write.endTransmisstion to see if
    // a device did acknowledge to the address.
    Wire.beginTransmission(address);
    error = Wire.endTransmission();
 
    if (error == 0)
    {
      Serial.print("I2C device found at address 0x");
      if (address<16)
        Serial.print("0");
      Serial.print(address,HEX);
      Serial.println("  !");
 
      nDevices++;
    }
    else if (error==4)
    {
      Serial.print("Unknow error at address 0x");
      if (address<16)
        Serial.print("0");
      Serial.println(address,HEX);
    }   
  }
  if (nDevices == 0)
    Serial.println("No I2C devices found\n");
  else
    Serial.println("done\n");
 
  delay(5000); // wait 5 seconds for next scan
}

fixed. d2 (gpio14) doesn't mean 2 is the pin. 14 is the correct pin to code for.

I also have a few ESP8266 + OLED projects here.
