Have some one managed to control and IC WS2801 with labview?

It's a LED Pixel control IC that contains VSS, GND and DI as their inpur and VSS, GND and DO as their outputs.

Take a look at the Giant Tetris link in my signature - I used a myRIO to control a string of 200 WS2801-based LEDs. You can also do it fairly easily with an FTDI lead (5V TTL USB to RS232 converter with the pins broken out) as that's what I used for my initial work on it.

You didn't mention what hardware you were using.

Hola Sam

I started this using an Arduino, however it is not what I am really looking at.

That component (and also the WS2811) have those specific I/O pins, so my wonder is if just using LabView we can control them.

Given your input of the USB-to RS232 converter, I will give a try and see.

BTW, I looked at your Giant Tetris project and looks really impressive, I will also give a try to it in the upcoming weeks.

Something like the 5V version of the converters here is what I used: http://www.ftdichip.com/Products/Cables/USBTTLSerial.htm

There is a LabVIEW provided by FTDI for using it in D2XX mode which is what you need for outputting SPI data (clock + data) for the WS2801.

WS2801 just same as APA102 LED Which have clock and data , you need to find the SPI code which have clock and data , ws2811 only have data.
