Abstract
In a serial, bidirectional data transmission method for communication between a programming device and a service device which is to be programmed, such as a hearing device, data are transmitted from the programming device and clock pulses are transmitted to the service device for individual adjustment of the application-specific data of the service device. Using a single signaling line, clock pulses that are variably formed for data transmission, are applied at the signaling line, and the digital information is recovered at the service device side by means of clock pulse variation and is subsequently processed with the transmitted clock pulse. Clock pulsewidth variation is performed as the clock pulse variation.
