I am trying to interface an I2C sensor on ESP8266.
I would like to use the GPIO0 and GPIO2 pins for the I2C_SCL and I2C_SDA signals.
Unfortunately, it seems that the GPIO0 pin creates some problems, both if used as I2C_SCL or
if used as I2C_SDA.
I am developing on the official Espressif ESP8266-DevKitC board.
I noticed that on this board the GPIO0 pin is connected to the reset button, as shown in the attached figure.
Could this particular create problems for I2C communication?
Could anyone help me?
