Multiple FadeCandy's about ofxopc HOT 6 CLOSED

Hi @ImanolGo,

I haven't tried unfortunately.

This may be wrong but, you could work around multiple units by creating two fcservers changing the port address. Then in the oF app create two ofxOPC objects assign them with different port numbers then pass the color information out that way.

I know that you can assign the units start address. So the first unit starts at 0 to 512, then you can set the second unit to start at 513 to 1024. All you would do is increase the length of Channels x 2.

Its line 24 of ofOPC.cpp from

uint16_t data_length = 8 * 64 * sizeof(OPCPacket_SPCData_t);

to

uint16_t data_length = 16 * 64 * sizeof(OPCPacket_SPCData_t);

I'll have a look round see what i can do.

Best

Hi @DHaylock

I finally left

uint16_t data_length = 8 * 64 * sizeof(OPCPacket_SPCData_t);

But had a signed a different OPC channel for each FadeCandy.

OPC_SPC_packet->header.channel = channel;

Then on the server side I configured it like,

{
"listen": [ "127.0.0.1", 7890 ],
"verbose": true,
"color": { "gamma": 2.5, "whitepoint": [ 1, 1, 1 ] },
"devices": [
{
"type": "fadecandy",
"serial": "XXXXXXXX1",
"map": [ [ 1, 0, 0, 512 ] ]
},
{
"type": "fadecandy",
"serial": "XXXXXXXX2",
"map": [ [ 2, 0, 0, 512 ] ]
}
]
}

And "voila", that worked perfectly for me.

Theoretically that should work for up to 256 different Fadecandys, which a fairly big amount of them.

Thanks,

Imanol

Thats fantastic, I know its a bit cheeky but would be interested to see what you do with it? I'll add to the readme later this week

Sure, no problem.

It will be a light sculpture made with 11 fadecandys and 85 independent neopixel rings. Unfortunately, it's not built yet. I'm just implementing the software and testing the prototype.

If you are curious, here is the full software that I implemented:
