Abstract
For a bi-directional bus topology, a node connection includes two select line connections for a select line of a serial network. The select line is broken at the node connection. A bus direction module configures a first select line connection for an input line and a second select line connection for an output line in response to detecting a selection event. At least a portion of the bus direction module includes one or more of hardware and executable code, the executable code stored on a memory.
Claims20
An apparatus comprising:
- a node connection comprising two select line connections for a select line of a serial network, wherein the serial network is a Local Interconnect Network (LIN) and the select line is discontinuous at the node connection;
- a bus direction module that listens at the two select line connections for a selection signal, wherein the selection signal is a LIN selection signal, and in response to detecting a selection event of receiving the selection signal at a first select line connection, the bus direction module configures the first select line connection for a LIN input select line and a second select line connection for a LIN output select line, and outputs the selection signal on the second select line connection to a second node connection;
- wherein at least a portion of the bus direction module comprises one or more of hardware and executable code, the executable code stored on a memory.
A method comprising:
- detecting a selection event at a node connection comprising two select line connections for a select line of a serial network, wherein the serial network is a Local Interconnect Network (LIN) and the select line is discontinuous at the node connection;
- listening at the two select line connections for a selection signal, wherein the selection signal is a LIN selection signal;
- in response to detecting a selection event of receiving the selection signal at a first select line connection, configuring the first select line connection for a LIN input select line and a second select line connection for a LIN output select line;
- and
- outputting the selection signal on the second select line connection to a second node connection.
A system comprising:
- an originator device that originates a selection signal;
- a node device comprising two select line connections for a select line of a serial network, wherein the serial network is a Local Interconnect Network (LIN) and the select line is discontinuous at the node connection, and the node device listens at the two select line connections for a selection signal, wherein the selection signal is a LIN selection signal, and in response to detecting a selection event of receiving the selection signal at a first select line connection, configures the first select line connection for a LIN input select line and a second select line connection for a LIN output line, and outputs the selection signal on the second select line connection to a second node connection;
- wherein at least a portion of the originator device and the node device comprises one or more of hardware and executable code, the executable code stored on a memory.
