Abstract
This paper designs the hardware and software interface of the 1-Wire slave device based on MSP430 MCU. It gives the hardware circuit schematic and the software flow, describes the working principle. The design of hardware is very easy to use and the costs are low because the hardware of the 1-Wire bus slave device includes a MSP430 MCU and some ordinary components only. The software is easy to program and expends its function so for different purposes. By this design, the scope of application of 1-Wire bus is expended. The device has none interface of 1-Wire bus can communicate with MSP430 first and then communicate with master by the simulative 1-Wire bus slave device interface based on MSP430. If system has used 1-Wire device, using this design could reduce the complexity because need not use other information protocol.
