Abstract
Embodiments are provided that include a light emitting diode (LED) controller connectable to a matrix of LEDs. A start code is received via at least one input pin, and a selected curve profile is retrieved from a programmable local memory in response to receipt of the start code, wherein the programmable local memory stores a set of curve profiles, each of which is associated with a different start code. A set of coefficients of a polynomial calculator are initialized to a set of values defined in the selected curve profile, wherein the set of values represent a light output curve. A sequence of light intensity values are calculated according to the polynomial calculator, and at least one pulse width modulation (PWM) signal is generated based on the sequence of light intensity values, wherein the at least one PWM signal controls light output of at least one LED.
