Abstract
Slave devices, master devices, systems and methods are disclosed for bidirectional edge-based pulse width modulation protocol based communication. In an implementation, receiving a master trigger signal starts a timer having an associated time period in a slave device, and after the timer has elapsed the slave device transmits a response.
Claims18
A slave device, comprising:
- a communication circuit configured to communicate based on a bidirectional edge-based pulse width modulation protocol;
- and
- a timer configured to start when the communication circuit receives a predefined trigger signal and to elapse upon expiration an associated time period after a starting of the timer,
- wherein the communication circuit is configured to transmit a response to the predefined trigger signal when the timer elapses,
- wherein the associated time period has a length to accommodate at least one further response transmitted by at least one further slave device.
2 more elements
A master device, comprising:
- a communication circuit configured to communicate based on a bidirectional edge-based pulse width modulation protocol,
- wherein the master device is configured to send a predefined trigger signal to a plurality of slave devices, and to receive responses from at least two of the plurality of slave devices in response to the predefined trigger signal one after the other,
- wherein the communication circuit is configured to transmit a predefined completion signal after each received response.
A communication system, comprising:
- a master device comprising a communication circuit configured to transmit a master trigger signal on a bus;
- and
- a plurality of slave devices coupled to the bus, each slave device comprising:
- a communication circuit coupled to the bus;
- and
- a timer configured to start when the communication circuit of the respective slave device receives the master trigger signal, and to elapse upon expiration of a respective associated time period after the timer has been started,
- wherein the communication circuit is configured to transmit a response to the master trigger signal when the timer elapses, and
- wherein respective associated time periods of different slave devices differ from each other.
5 more elements
A communication method, comprising:
- receiving a master trigger signal according to a bidirectional edge-based pulse width modulation protocol;
- starting a timer in response to receiving the master trigger signal, wherein the timer elapses upon expiration of an associated time period after starting;
- and
- transmitting a response to the master trigger signal when the timer elapses,
- wherein the associated time period has a length to accommodate at least one further response transmitted by a further slave device.
2 more elements
A communication method, comprising:
- sending a master trigger signal according to a bidirectional edge-based pulse width modulation protocol over a bus;
- in a plurality of slave devices, starting a respective timer in each slave device responsive to receiving the master trigger signal;
- and
- in each of the plurality of slave devices, transmitting a response when the respective timer of the slave device has elapsed, wherein respective timers of the plurality of slave devices elapse after different associated time periods.
