Abstract
A system includes lighting devices coupled to output supply pins, a microcontroller circuit, and a driver circuit, which receives data therefrom, and switches coupled in series to the lighting devices. The driver circuit includes output supply pins and selectively propagates a supply voltage to the output supply pins to provide respective pulse-width modulated supply signals at the output supply pins. The driver circuit computes duty-cycle values of the pulse-width modulated supply signals as a function of the data received from the microcontroller circuit. The lighting devices include at least one subset coupled to the same output supply pin. The microcontroller individually controls the switches via respective control signals to individually adjust a brightness of the lighting devices in the at least one subset of lighting devices.
