Abstract
Provided is a light emitting diode (LED) driver. The LED driver includes a microcontroller for setting a level of an output current of the driver. The driver is configured to receive a prefix as an input, the prefix instructing the microcontroller to enter a programming mode. The microcontroller is responsive to a level signal representative of the level of the output current during the programming mode.

A light emitting diode (LED) driver, comprising:
- a microcontroller for setting a level of an output current of the driver;
- wherein the microcontroller is configured to receive, within a programming cycle, an instruction signal including (i) a non-analog prefix signal segment instructing the microcontroller to enter an output current programming mode and (ii) an analog programming signal segment in sequence after the prefix signal segment;
- and
- wherein the analog programming signal segment is configured to set a level of the output current responsive to a magnitude of a voltage of the analog programming signal segment.
A method of programming a light emitting diode (LED) driver including a microcontroller configured to set a level of an output current of the driver, the method comprising:
- receiving within a programming cycle, in the microcontroller, an instruction signal including (i) a non-analog prefix signal segment instructing the microcontroller to enter an output current programming mode and (ii) an analog programming signal segment in sequence after the prefix signal segment;
- wherein the analog programming signal segment is configured to set a level of the output current responsive to a magnitude of the voltage of the analog programming signal segment.
A tangible computer readable media storing instructions wherein said instructions when executed are configured to execute processes within a computer system, with a method comprising:
- receiving within a programming cycle, in the microcontroller, an instruction signal including (i) a non-analog prefix signal segment instructing the microcontroller to enter an output current programming mode and (ii) an analog programming signal segment in sequence after the prefix signal segment;
- wherein the analog programming signal segment is configured to set a level of the output current responsive to a magnitude of the analog programming signal segment.
