IBUTTON 1-WIRE DRIVER DOWNLOAD

The basic sequence is a reset pulse followed by an 8-bit command, and then data is sent or received in groups of 8-bits. Communication occurs when a master or slave asserts the bus low, i. Each device on the bus has a unique bit serial number. Since the address includes the device type and a CRC, recovering the address roster also produces a reliable inventory of the devices on the bus. Apple MagSafe and MagSafe 2 connector-equipped power supplies, displays, and Mac laptops use the 1-Wire protocol to send and receive data to and from the connected Mac laptop, via the middle pin of the connector.
