Hi Eddiie,
Thank you for all of that information. I am working with a device that is most likely expecting 5v levels. It is not working currently with the ESP8266, will try adding level shifter and see, maybe do a capture to see what the bus looks like.
Hello,
I have a question. ESP8266 is using 3.3v on the GPIO pins, right? I am assuming most I2C devices are 5v.
Are you assuming a logic level converter is in use or is there no issue between the 3.3 and 5v. OR am I just wrong and all I2C is 3.3v?
Unfortunately, I forgot the second question. grrr
