#62366 I am using Arduino IDE
I have a ESP-12
I have a : HTU21D (temp and humidity over I2C)

I have SDA connected to Pin 0
I Have SCL connected to Pin 2
Common Ground, and VIN connected to 3.3v

Using both the SParkfun code https://github.com/sparkfun/SparkFun_HTU21D_Breakout_Arduino_Library and the Adafruit code https://github.com/adafruit/Adafruit_HTU21DF_Library, both are not finding the board. In both cases, its just a push straight to the board, no code changes.

ANy ideas please?
