Abstract: Devices, systems and methods are disclosed for assigning unique addresses to slave devices in a system comprising a host controller and multiple slave devices connected in a daisy chain configuration. The host controller initiates the address programming protocol, resulting in address assignment commands propagating along the daisy chain to each of the slave devices. Upon receiving an address assignment, each slave device issues an updated address assignment for the neighboring downstream slave device in the daisy chain. In this manner, slave devices are uniquely addressed using a single command, such that slave devices do not require factory-programmed device addresses. Also disclosed are communication protocols that allow the host controller to communicate with each of the daisy-chained slave devices or with certain subsets of the slave devices. Via the protocol, the host controller can communicate with any slave device in the daisy chain, while utilizing only the daisy chain connections that link the individual slave devices.

Abstract: A system including an integrated circuit chip also includes a microcontroller in the chip and an algorithm for execution by the microcontroller. The algorithm includes addition, subtraction, and multiplication operators (e.g. 25,15,20) and shift-left and shift-right operators (e.g., 48,21) configured for solving particular equations (Eqns. 1-4). Input numbers are within particular ranges to allow the shift operators to shift binary bits so each number so it fits within a register of a particular width. An IR sensor (4) may convert IR radiation (3) to produce a voltage (Vobj) representing the temperature (Tobj) of an IR emitting object (2). The algorithm (100) operates in conjunction with the microcontroller (7) to convert the voltage (Vobj) into a value representing the temperature (Tobj) of the remote object (2) without keeping track of decimal points and resolution of the numbers.
