Define Pin Wire. If you call the wire.begin(sda_pin, scl_pin). There is sda0 and scl0 at, respectively, pins 20 and 21. The distinguishing feature of i2c over spi is that it uses only two wires to carry out communication. The esp8266 core wire library already has an api function to set the pins used. When using the esp32 with the arduino ide, the default i2c pins are: The i2c protocol involves using two lines to send and receive data: A serial clock pin (scl) that the arduino controller board pulses at a regular. The esp32 has two i2c channels and any pin can be set as sda or scl. Arduino io pins can tolerate up to 5.5v for any io pin. However, it also depends on the voltage level that the i2c slave device can tolerate. #define pin_wire_sda (25u) #define pin_wire_scl (26u) to pins you need. One wire is scl (serial clock line) which synchronizes the transmission. On arduino due, there are two pairs of sda/scl pins that i can use for i2c. If it works, consider to define your own hardware.
