Abstract
A method for performing a data communication between at least two devices, wherein, the at least two devices are connected via an electrical bus line, each of the devices detects the magnitude of a device current flowing from the respective device to the bus line, one device increases the device current of the other devices in order to announce the transfer of data, and data is transferred after announcing the transfer of data by means of modulation of the device current of the other devices.
Claims13
A method for performing a data communication, said method comprising:
- connecting at least two devices via an electrical bus line;
- detecting in each of the devices a magnitude of a device current flowing from the respective device to the bus line;
- announcing an initiation of a transfer of data by one device increasing a current of other devices;
- transferring data after announcing the transfer of data by means of modulation of the device current of the other devices.
The method of at least one of the previous claims, wherein
- during the transfer of data by means of modulation of the device current, the transferring data includes modulating device current using Manchester code.
The method of at least one of the previous claims, wherein
- transferring during the transfer of data, first an address of a target device is transmitted followed by the data destined for the target device.
The method of at least one of the previous claims, wherein
- transferring data comprises modulating device current using only a single electrical bus line.
The method of at least one of the previous claims, wherein
- the electrical bus line (18) is only arranged on a printed circuit board.
The method of at least one of the previous claims, wherein
- only one device at a time increases the device current of the other devices.
A device for performing a data communication, wherein the device is adapted to be connected to an electrical bus line;
- detect the magnitude of a device current flowing from the device into the bus line;
- increase the device current of other devices connected to the bus line to announce the transfer of data;
- transfer data after announcing the transfer of data by modulating the device current of the other devices;
- and
- receive data by detecting a modulation of its device current.
