First off - thank you for having a great community! I just wish more used this place for Arduino development.

I do have a question regarding using the TM1803 on the RadioShack Tricolor LED strip and FastSPI_LED2.r3.

After spending a few moments scratching my head when the strip colors was way off. I ran the RGB Calibration program to find they wiring on the RadioShack Tricolor Strip was GGBBRR (Green, Blue, Red). Now that I know this, how do I go about setting this up so calls to FastSPI members .r/.g /.b work in correctly?

you would change THIS line;
FastLED.addLeds<TM1803, DATA_PIN, RGB>(leds, NUM_LEDS);

to
FastLED.addLeds<TM1803, DATA_PIN, GBR>(leds, NUM_LEDS);

I started to play with that but wasn’t sure how it was interpreted. Thanks!

That’s what the rgb in that line is for. My cheapo ws2811’s are grb and I had a similar issue!
