DS2482: I2C to 1-wire DS2482-100: I2C to 1-wire bridge device Interfaces with standard or fast I2C masters to perform bidirectional conversion between I2C master and downstream 1-Wire slave devices Relative to 1-Wire slave devices, it acts as 1-Wire master 12
SPI Signals Four main signals: Master Out Slave In (MOSI) Master In Slave Out (MISO) Serial Clock (SCK) Chip Select (CS) Since there is a separate CS for each device on board, SPI does not scale up well in comparison with I2C MOSI: Generated by master, received by slave Also labeled as Serial Input (SI) or Serial Data In (SDI) MISO: Generated by slave, under control by the master Also labeled as Serial Output (SO) or Serial Data Out (SDO) Chip Select (Slave Select) generated using spare I/O of master 13
