Espressif SDK HTU20D I2C
Posted: Sat Jun 18, 2016 5:56 pmHi,
I currently struggle with the HTU20D Sensor on the ESP8266. I'm using the software I2C from espressif. When I use the sensor on a standard Arduino UNO I get a ack after adressing the sensor. With the esp8266 I get no ack after adressing. As seen in the Oscilloscope shots in the attachement.
Does anyone know how this can be? The waveforms are exactly the same. Only the timings vary a little bit.
