Madmapper/Arduino Mega

All, I made a video of my situation. I have the LED's wired through an Arduino and I followed the tutorial for the FastLED serial connection. As you can see in the video, madmapper is talking to the arduino, but the LED's aren't coming on. The LED test works fine, but I just get nothing when trying to drive them from madmapper.

Here is a video to the setup:

Thanks for any help you can give me!!

Just an update... I gave up on the mega. I did use a Teensy and wasn't able to get any LED's to light up. I ended up commenting out these lines from the FastLED-serial-only-single-line.ino and it fixed it:

Code: Select all

//while (!Serial) { // wait for serial port to connect. Needed for Leonardo only //}

Thanks for your feedback. I'll update the ZIP file with this line removed.
Cheers !
