FPS Limit

[jnordberg]

I'm using LEDscape to drive just a handful of ws281x LEDs and I'm seeing a CPU usage of about 40%. Is it possible to limit the fps? I don't really need 3k updates per second :)

j, what does your json config look like?

{
    "outputMode": "ws281x",
    "outputMapping": "rgb-123-v2",
    "demoMode": "fade",
    "ledsPerStrip": 4,
    "usedStripCount": 1,
    "colorChannelOrder": "RGB",
    "opcTcpPort": 7890,
    "opcUdpPort": 7890,

        "green": 1.0000,
        "blue": 1.0000
    }
}

Oh wow, you are only running a few strips. You may want to turn off dithering and interpolation by setting these to "false"

[jnordberg]

Yeah I realise that my usage isn't what this lib was written for :) Setting interpolation and dithering had no effect, but I found that increasing the number of LEDs per strip did, managed to get it around 10% with 64.

You're absolutely right that this sort of small setup isn't what LEDscape is currently optimized for, but I think it's a good direction to move in. I would welcome and pull requests for this sort of functionality.
