This sensor has a simple I2C interface that is similar to many other I2C devices and will help demonstrate basic I2C master usage. This guide will also focus on the ESP8266 MicroPython port, but you should be able to use similar code on other MicroPython boards.

Arduino - MasterWriter

I2C from two masters (ATtiny85, ESP8266) to one slave (ATmega328) (Arduino) configured as slave, receives messages from an ATtiny (ATtiny85, ATTinyCore by SpenceKonde) configured as master, or from an ESP8266 (ESP-01, Arduino core) configured as master. Apparently someone made a ESP8266 I2C slave library: :

I2C Slave Mode - ESP8266 Developer Zone

ESP8266-01 using Arduino IDE. Upon powering up, the ESP8266 will initialize the SSD1306 (I2C) OLED, will scan all surrounding networks looking for the specified network, and upon finding the home network, will attempt to connect and log-in to the WiFi router. On my workstation, this appears as: \Documents\Arduino\hardware\ESP8266

Wire library currently supports master mode up to approximately 450KHz. Before using I2C, See attached example for reference. DNS server (DNSServer library) While many RC servo motors will accept the 3. 3V IO data pin from a ESP8266, most will not be able to run off 3. 3v and will require another power source that matches their

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; 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.
