| 摘要 |
The invention relates to a simple serial data transfer method for the exchange of data between two electronic bus stations (33,32). The bus connection consists of two lines wherein the first line is dedicated to data/control signals and a second line (19) is dedicated to a power supply voltage. A data transfer from the transmitting station (33) to the receiving station (32) is started by pulling the first line to an activated potential for a first period of time (Tactive). After elapse of the first period of time (Tactive) the transmitting station leaves said first line (22) inactive for a second period of time (Tstable). The transmitting station commences data transmission via said first and second line after elapse of said second period of time (Tstable). <IMAGE> |
