I2C from two masters (ATtiny85, ESP8266) to one slave
You could use this for example if you're creating a sensor in MicroPython that exposes its data to other boards with I2C. Currently the pyboard is the only board that supports I2C slave mode. In particular the ESP8266 MicroPython port does not currently support I2C slave mode.
ESP8266: I2C PORT and Address Scanner: 8 Steps
ESP8266 to ESP8266 i2C Communication. Ask Question 2. 1. I am trying to get my ESP8266's connect and send messages over an i2c bus. I am using a NodeMcu Development Board. ESP8266(I2C Master) to ESP8266(I2C Slave) works from version 2. 5. 0. Check out my comments on the ESP8266 GitHub. share | improve this answer.

ESP8266; WeMos Mini D1 - Default I2C I2C. I2C can be used to connect up to 127 nodes via a bus that only requires two data wires, known as SDA and SCL. SPI is much simpler than I2C. Master and slave are linked by three data wires, usually called MISO, (Master in, Slave out), MOSI (Master out, Slave in) and M-CLK.
