RGB Led - is it possible to pulse between two varying "non-primary" intensities?

It SAW's fine, the colors aren't what I expect.

I have been following it, and I'll look into that as a potential problem when I get home. I'll post results later tonight.

If your SAW'ing then your probably not seeing the problem.  R,G and B work independently?  It's just the color mixing that doesn't seem right?  Are these Randy's RGB LED's or someone elses?

2600:
Maybe I don't understand and I could be wrong, but I don't think you understand what the SAW is doing.


Taking just one output, the SAW starts from the lowest intensity and ramps up to the highest intensity and then ramps back down to the lowest intensity.  This is why you can't use the intensity controls, because by the definition of the SAW waveform it is changing the intensity.

So what you want to do is use LumAura toprogram a set of sequences and save it.  Looking  at your one post you want:

1. The first frame to be RED (48) + GREEN (27).
2. The second frame to be RED (48).

I forget what the command is for repeat, but someone else can fill that in.  Also, not sure if you wanted to change the duration of each frame.  Should take you 5-10 seconds.



Post should probably be moved to Main, since it has nothing to do with PowerMAME.

mr.Curmudgeon:
Yeah. Feel free to move this (mods?) if necessary. I'm going to toy around with the LED's more this weekend and see if I can't create the color phasing I'm looking for.

I'll post back with a better example, (maybe a movie or something) if I'm still running into the problem.
