Hello,
Im getting started with touch and have followed loads of tutorials online explaining how to set up LEDs via artnet
Some tutorials say that you should have a shuffle chop set to “Split N samples” which should be 3 times the total number of LEDs, after the “Sequence all samples” chop.
Is this needed, I cant see any change in my LEDs when bypassing the chop
Cheers
The point of all of the CHOPs before the DMXout CHOP is just to get your data into the proper format for the DMX protocol. The DMX protocl is so old that it requires you to send out your data in subsets of 512 values called “universes”. You can use whatever combination of CHOPs (usually shuffle) to get your data into channels that are no longer than 512 samples each, and in each channel, the samples should be each color for a pixel in a row - IE usually like RGBRGBRGB so 3 samples will control one pixel’s red, green, and blue values.
This usually means that you can only fit 170 pixels worth of data into one DMX universe (170 * 3 = 510 which is two less than 512) so if you are sending more than 170 pixels worth of data, you might need to split that one long single channel of interleaved RGB samples into many channels, hence split X samples would come in handy in that case.
