Abstract
A system may include a plurality of slave devices connected to a master device via a bus interface that includes a communication line and a plurality of select lines. The communication line may connect the master device to each of the plurality of slave devices and may permit bi-directional, one-wire communication among the master device and the plurality of slave devices. A select line, of the plurality of select lines, may connect the master device to a slave device, of the plurality of slave devices, and enable signaling, associated with the bi-directional, one-wire communication, between the master device and the slave device.
Claims24
A system, comprising:
- a plurality of slave devices connected to a master device via a bus interface that includes a communication line and a plurality of select lines,
- where the communication line connects the master device to each of the plurality of slave devices and permits bi-directional, one-wire communication among the master device and the plurality of slave devices, and
- where a select line, of the plurality of select lines, connects the master device to a slave device, of the plurality of slave devices, and enables signaling, associated with the bi-directional, one-wire communication, between the master device and the slave device.
A system, comprising:
- a master device to:
- signal, via a select line associated with a slave device, that the master device is to transmit information via a communication line,
- where the master device is connected to the slave device via a bus interface that includes the communication line and the select line,
- where the communication line permits bi-directional, one-wire communication between the master device and the slave device, and
- where the select line enables signaling by the master device to be detected by the slave device;
- and
- transmit, based on signaling via the select line, the information on the communication line;
- and
- the slave device to:
- detect the signaling on the select line;
- and
- receive the information, via the communication line, based on detecting the signaling on the select line.
A system, comprising:
- a set of slave devices;
- a master device;
- a bi-directional, one-wire communication bus connecting the master device and the set of slave devices;
- and
- a set of select lines connecting the master device and the set of slave devices,
- each select line, of the set of select lines, connecting the master device to a respective slave device of the set of slave devices.
