LED Rainbow

RGB LED PWM Driver - v3 Firmware Details

LED Rainbow Assembled Front ViewThe LED Rainbow contains a pre-built set of routines in it. The initial public release of the firmware was version 2.0 which contained over 30 various fades, flashes and color combinations. On March 20, 2009, version 3 of the firmware was released and now contains over 50 different sequences.

New in version 3 in addition to the extra sequences, is the placement of “markers”. Markers allow you to quickly determine where in the list of sequences you are located. Positioned every ten sequences, there is a special sequence which blinks out the current location. For example, if you were at sequence 30, the LEDs would blink three times; and the same for position 10, 20, 40 and 50, with one blink for every ten positions. The exception to this is the sequence located at position 60, this is actually the last usable sequence and is not a position marker. The sequence located at position 61 (the last sequence on the chip) is use to identify the version of firmware which will blink just the green channel three times (for version 3 of the firmware).

Each effect is selected by pressing of the Mode (S1) button. The LED Rainbow will remember the last sequence you were using after 10 seconds of viewing it, which when powered on at a later date will automatically start with your last viewed sequence.

Looking for reference to the version 2 firmware? The support page for the version 2 firmware is available for reference.

We have attempted to describe the various effects below, but the descriptions cannot describe just how good the LED Rainbow displays the combinations. We encourage you to use the chart as a reference. The version 3 firmware is available for immediate download from the Programming page.
