METHOD AND APPARATUS FOR TRANSMITTING OF DATA BETWEEN MASTER AND SLAVE

摘要

PURPOSE: A method and a device for transmitting data between a master and a slave are provided to transmit presence of transmission data in the salve when the slaver has the transmission data for the master, thereby reducing overhead of data. CONSTITUTION: A data transmitting device comprises a master(100), a slave(200), and an SPI(Serial Peripheral Interface) unit. The master controls data communication of a sensor node in a wireless sensor network. The slave transmits data according to a control operation of the master. The SPI unit is connected between the master and the slave. The SPI interface unit transceives data between the master and the slave in a serial transmission type.
