Synced animations

Grid

Hi, is there anyway to sync LED animations? If I start different animations at different times, they all run indepependently of each other whereas I’d like them all to sync up and operate on the same cycle.

thx

Curious about this as well. It would be nice if there were a way to keep LED animations phase-aligned.

Hey guys,

Maybe using the system timer might be useful for this purpose? I wanted to try this out to learn how it works, and I managed to create a custom animation (saw up) with resync. I’m not sure if this will be useful, but here’s what I’ve got so far:

I’ve uploaded it to my profile cloud (if that helps) grid-editor://?config-link=v14X21qlKGmAEYKdnapy

Apologies for any code mistakes—I’m still very new to using the grid editor!
Cheers

I’ve updated it with a global shape variable so we can select the animation waveform (on System Setup)

shp =
0 - Saw Up
1 - Saw Down
2 - Pulse
3 - Sine

Cheers

Any possibility of just posting the relevant code snips here? The grid:// link doesn’t work. Also, if it’s posted in a public profile, I don’t see anything relevant. Lots of random stuff in there.

Much appreciated!

hey, sure!

I can post here, is there any way to share it like a file? it would be cool.

-- On System SETUP
ms = 10
shp = 3
ramp = -1
function reset(x)
    if x > 0 then
        ramp = -1
        timer_start(16, ms)
    elseif (x <= 0) then
        ramp = -1
    end
end

-- On System UTILITY 
ms = math.max((ms + 10) % 40, 10)

-- On System TIMER 
timer_start(16, ms)
ramp = (ramp + 1) % 128
function wave(r, t)
    return t == 1 and 127 - r or t == 2 and (r < 64 and 127 or 0) or
        t == 3 and math.floor((math.sin((r / 127) * 2 * math.pi - math.pi / 2) * 63.5) + 63.5) or
        r
end
for i = 0, 15 do
    led_value(i, 1, element[i]:button_value() > 0 and wave(ramp, math.min(shp, 3)) or 0)
end

-- on every button you want the animation - I have BU16 
reset(val)

Shp global variable range is 0…3, (saw up, saw down, pulse, sine).

The problem I see, there is not much room for coding more things due to the 400 character limit.

Hope this helps,
Cheers!

You can save the profile in the Grid Editor. Just make sure to save it in the 'Community ’ section of the cloud profiles. I believe the link you shared would work if it were under the correct section. Your link is sharing a ‘My configs’ profile which would be private :slight_smile: :

thanks!

Yes, I’ve tried uploading it to the cloud, making it public, etc. But I can’t get it in the community section. Maybe there is a step that am I missing?

Thank you again!

Unsure. I don’t have any profiles to share. Mine are all hyper-specific to my setup so I’m not familiar with the process of posting them publicly.
