    Why I2C is an 8-bit address??

    Isn't the standard I2C communication protocol 7-bit address with 1-bit read and write flag bits?

    Hi Geralt,

    1.Memory map table showed register and their address, not mean I2C device addrss;
    2.The press value contains 20 bits, and xlsb is its lower four bits [3:0].
    3.This is standard I2C communication.

    Why can't I use it after reading the 'BME680 Datasheet' ? Is it my problem or is the data sheet not clear?
