The LED PWM API for myRIO by Darin Kinion extends the FPGA personality of myRIO to allow individual brightness control of onboard LEDs. Simple pulse-width modulation switches the LEDs on and off more quickly than the human eye can discern. Using this API with code on myRIO real-time targets produces perceptible flashing/throbbing of the LED, but the FPGA speed allows you to see the average light level. Functions include getting/setting brightness or the state for one or all of the onboard LEDs, and convenience functions to combine these settings into a single subVI.

With the reintroduction of an analog component to the digital realm, brightness control increases the amount of conveyed information. Instead of indicating 16 different distinct states, adding a brightness component adds richness to the display. A stark blinking LED can be replaced by a more pleasing ramp, and busy indicators can be more interesting. Example lighting effects, including waves and ramps, are provided.
