Abstract
A master/slave system architecture including a single wire bus and master device and bus interface coupled to the bus. The system further includes slave devices having respective bus interfaces coupled to the bus. The system further includes a communication protocol implemented over the single wire bus and employed by the master and the slave devices. The protocol includes bus transactions for communicating between the master and the slave devices. The communication protocol further includes Master Slave Operational Interface (MSOI) that includes repertoire of functions properties stored in the master device, whereby, the master can communicate with any slave device that supports functions properties that belong to the repertoire of functions properties, using the bus transactions, substantially without need of retrofit.
