    • A device and a method are described for bidirectional single-wire data transmission of information between a control unit and at least one peripheral unit, having the following steps: generating a first current flow from the control unit to the peripheral unit during first time slots via a single-wire line to transmit voltage-coded or current-coded information from the control unit to the peripheral unit; and/or generating a second current flow from the peripheral unit to the control unit during second time slots via the single-wire line to upload voltage-coded or current-coded information from the peripheral unit to the control unit; the first and second time slots being implemented so they do not mutually overlap; and/or generating, in the first and/or second time slots, additional information to be transmitted and/or uploaded, which is transmitted as digital or analog signals by modulating the current or the voltage of the single-wire line and is analyzed in the control unit or the peripheral unit.
    • 描述了用于在控制单元和至少一个外围单元之间进行信息的双向单线数据传输的装置和方法,具有以下步骤:在第一时隙期间经由所述控制单元生成从控制单元到外围单元的第一电流 用于将来自控制单元的电压编码或电流编码信息传输到外围单元的单线线路; 和/或在第二时隙期间经由单线线路产生从外围单元到控制单元的第二电流,以将来自外围单元的电压编码或当前编码的信息上传到控制单元; 第一和第二时隙被实现,使得它们不相互重叠; 和/或在第一和/或第二时隙中产生将被发送和/或上传的附加信息,其通过调制单线线路的电流或电压而被作为数字或模拟信号发送,并在 控制单元或外围设备。
