Control RGB LED WS2812 with NI PCI-6133 and LabVIEW

[MichaGue_01]

Hello, is it possible to control a RGB LED WS2812 with LabVIEW and the DIOs of a NI PCI-6133?Are there any examples available: I have only found an example for RIO control: https://forums.ni.com/t5/Example-Code/RIO-control-of-WS2812-programmable-LEDs/ta-p/3528282?profile.l...

Thanks a lot and best regards,

Michael

Looks like this website give you most of what you need to know. THe rest will be building the circuit and then putting together the voltage output and bluetooth communications to do what you need to do. Look at the code they provide and you should get an idea of where you need to go.

Hello everyone, for all interested people my solution to control a RGB LED WS2812 directly with a DAQmx hardware and LabVIEW.

Used hardware:
- Win 10 PC
- LabVIEW 2016
- NI PCI-6133
- SCB-68
- Microe 4X4 RGB click

Basically the solution should work with all DAQmx cards that can generate a counter with a frequency of 5 MHz.

Attached you will find the vi and a short video.

Have fun and best regards,
Michael
