Abstract: Devices, systems, software, and methods for control of light emitting diodes (LEDs) via an LED driver circuit that receives a dimmed AC input signal from a dimmer and generates an output signal to power and dim an LED element. The LED driver circuit comprises a dimmed input sense circuit, a microcontroller, and a power supply circuit. The power supply circuit generates a power supply from the dimmed AC input signal for powering the LED driver circuit. The dimmed input sense circuit detects an incoming duty cycle Din of the dimmed AC input signal. The microcontroller stores one or more dimming level parameters, receives the detected incoming duty cycle Din from the dimmed input sense circuit, and generates an output duty cycle Dout based on the detected incoming duty cycle Din and the one or more dimming level parameters. The LED driver circuit generates the output signal using the generated output duty cycle Dout for powering the LED element at a generated dimming level.
