Abstract
A method, apparatus and program for dynamically allocating addresses to computer devices connected to Inter Integrated Circuit (I C) buses are provided. Upon resetting a I C bus, the invention uses a bus driver to turn on the first bus switch on the bus. The invention then accesses the first device downstream of the switch and allocates a new value to the device's address. The invention proceeds to turn on the next switch downstream. A new address is then allocated to the device downstream from the second switch. This process continues until all of the devices connected to the bus have unique addresses.
