A system for communicating between electronic devices on a communication bus includes a communication bus and one or more communication circuits each having an output driver coupled to the communication bus and each having an input terminal. Each communication circuit produces, in response to a request message, a data communication on the communication bus in a predetermined order with respect to data communications from other communication circuits so that the data communications from each communication circuit form a sequential data stream in response to the request message.

Communication system between electronic devices

A network slave device includes a transceiver for communicating over a communication bus in accordance with a point-to-point network protocol. The network slave device may include an address to identify the network slave device on the network. It may also include a communication circuit configured to process a command received by the transceiver and generate a reply for transmission over the communication bus if an address included in the command matches the address of the slave device. A master device communicating on the network may send commands including the address of the slave device in accordance with the point-to-point network protocol. In an embodiment, the point-to-point protocol is the SENT protocol.

Signaling between master and slave components using a shared communication node of the master component

A network slave device includes a transceiver for communicating over a communication bus in accordance with a point-to-point network protocol. The network slave device may have an address to identify the network slave device on the network. It may also have a communication circuit configured to process a series of commands received by the transceiver and respond to a command if a position of the command in the series of commands corresponds to the address of the network slave device. A master device communicating on the network may send the series of command in accordance with the point-to-point network protocol. In an embodiment, the point-to-point protocol is the SENT protocol.

A magnetic field sensor provides an angle error value to correct errors of the magnetic field sensor. The angle error value is a function of temperature and magnetic field strength and is used to correct a measured magnetic field angle. Associated methods are also described.
