If we then put a new slave on the bus before this slave for example, this means that the position number of the first slave will change and we need to reconfigure our code.? This presents problems.</div><div id="yui_3_16_0_ym19_1_1460722120709_8954" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1460722120709_8954" dir="ltr">My question is, can we not access the slave via their physical addresses instead of this incremental position addressing, therefore not needing to update the position address every time there is a change?</div><div id="yui_3_16_0_ym19_1_1460722120709_8954" dir="ltr"><br></div><div id="yui_3_16_0_ym19_1_1460722120709_8954" dir="ltr">Thanks</div></div></body></html>
