 Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me. |

That's the way the I2C bus works. Just as long as the address for each device is unique. David M. |

More devices on the line increases the capacitance on the line. This may then force you to go to lower speeds and / or lower value pull-up resistors. See information on this here. |
