Abstract
A communication method for a communication network of a vehicle includes a master data processing unit and a slave data processing unit connected to the master data processing unit via a synchronous serial communication interface. The slave data processing unit is connected to the master data processing unit via a slave select line for indicating that data is being sent from the master data processing unit to the slave data processing unit. The data sent from the master data processing unit to the slave data processing unit and/or from the slave data processing unit to the master data processing unit is framed by a start bit as a first bit and a stop bit as a last bit of the sent data.
Claims15
A communication method for a communication network of a vehicle, wherein the network comprises:
- a master data processing unit, and
- a slave data processing unit, wherein the master data processing unit and the slave data processing unit are both SPI devices communicatively coupled via a synchronous serial communication interface and via a slave select line for indicating that data is being sent from the master data processing unit to the slave data processing unit, wherein the synchronous serial communication interface connects the master data processing unit and the slave data processing unit via a master-out-slave-in line, a master-in-slave-out line, and a serial clock line,
- the method comprising:
- sending data from the master data processing unit to the slave data processing unit via the master-out-slave-in line and/or from the slave data processing unit to the master data processing unit via the master-in-slave-out line, wherein the sent data is framed by a start bit as a first bit and a stop bit as a last bit.
A communication network for a vehicle, comprising:
- a master data processing unit;
- and
- a slave data processing unit,
- wherein the master data processing unit and the slave data processing unit are both SPI devices communicatively coupled via a synchronous serial communication interface and via a slave select line for indicating that data is being sent from the master data processing unit to the slave data processing unit,
- wherein the synchronous serial communication interface connects the master data processing unit and the slave data processing unit via a master-out-slave-in line, a master-in-slave-out line, and a serial clock line, and
- wherein the master data processing unit is configured to frame the data sent from the master data processing unit to the slave data processing unit with a start bit as a first bit and a stop bit as a last bit of the sent data, and/or the slave data processing unit is configured to frame the data sent from the slave data processing unit to the master data processing unit with a start bit as a first bit and a stop bit as a last bit of the sent data.
