Method and device for programming a microcontroller

摘要

A programming device (100) for programming a controller (10) in an electronic driver (200) comprises a controllable voltage supply (30) for generating an AC supply voltage suitable for supplying the electronic driver (200) and a programming controller (20) for controlling the voltage supply (30). The programming device (100) is designed to modulate the supply frequency in order to both feed the electronic driver (200) and send programming data to the electronic driver (200).

1. Method for two-way communication, the method comprising:
transmitting data from an AC voltage source over an AC voltage supply line to a consumer device, the method comprising the step of generating AC voltage at a predetermined base frequency and using frequency modulation for modulating the base frequency; transmitting, simultaneously, data from the consumer device to the AC voltage source by drawing a current from the voltage source and modulating the amplitude of the current drawn from the voltage source, wherein the voltage source comprises a programming controller and a current sensor for sensing the current drawn from the voltage supply, the current sensor having an output coupled to a sense input of the programming controller, wherein the programming controller is designed to decode amplitude modulated information from the sensor output signal; the consumer device being a driver for a light source.
