Abstract
An embodiment method of command of an electronic device comprises controlling a screen to alternate periodically between a first phase in which the screen emits light and a second phase in which no light is emitted by the screen, and precharging a charge pump of an ambient light sensor during the first phases, the ambient light sensor comprising at least a single photon avalanche diode powered by the charge pump.
