I2C library for ESP8266

Postby djdehaan » Sun Oct 22, 2017 8:35 am

I bought the Freematics OBD-II I2C Adapter for Arduino. I want to connect a Wemos D1 mini, ESP8266. The provided library is developed for core Arduino boards. I had to change the Wire.begin command (as that needs D1,D2 as arguments) - the Wemos finds the Freematics I2C addresses. But obd.begin and obd.init will cause the ESP to hang.

Does anyone have a working setup with a ESP8266 as main processor?
Does anyone have a working library that I can use, or a description of the I2C commands for the Freematics?
