cnlohr @ github.com wanted to have an Ethernet interface for ESP8266 so he build one. more details on hackaday. This is a relatively unreliable and coincidentally functional ESP8266 Ethernet driver. It only uses two pins on the ESP, the I2S pins, but does provide Ethernet. It does all its own manchester encoding/decoding, framing, FCS, etc. It […]
