A programming device () for programming a controller () in an electronic driver () comprises a controllable voltage supply () for generating an AC supply voltage suitable for supplying the electronic driver () and a programming controller () for controlling the voltage supply (). The programming device () is designed to modulate the supply frequency in order to both feed the electronic driver () and send programming data to the electronic driver ().

Method and device for programming a microcontroller

A method is described for driving a light source, particularly a HID lamp (), the method comprising the steps of: providing a commutating DC current for supplying the lamp; and varying a commutation period (T) in order to transmit data. In an embodiment, the duration of each commutation period (T) is set to be equal to one of two possible values (T, T) such as to encode a digital bit.
