    I2C Communicating At Different Speeds?

    Hello, Is it possible to connect and communicate two I2C devices with each other on the same bus if the two devices work on different speeds?

    E.g. Device one is at 100 KBPS and Device 2 is at 400KBPS

    Re: I2C Communicating At Different Speeds?

    400KBPS devices will work on a 100KBPS bus (obviously at slower that optimum speed) but the slower device may not work at the higher speed. They are electrically almost identical so you can mix them on one 12C bus.
