Using USB-6008 to light up LED array(hardware)

Flibbertygibbet — Sun, 28 Jun 2009 03:45:21 GMT

I've created the coding to light up an array of LEDs at random, can someone teach me how to light up my hardware using the NI-USB6008 exactly as it lights up in the VI? thanks.

p.s: I've attached my VI and LED array schematic

Have you taken a look at the documentation? Page 21, to be specific. The USB-6008 digital lines are open-collector. This means you have to wire them up to sink current, meaning you will need an external power supply.

may I know how to do that? I'm fairly new to electronics and LABView.. thanks.

Maybe it's wise to protect your outputs with some drivers :some I found , but they might not be the best suited... (they should be cheap (<.5$) and on Stock >1k at digikey just to give you an idea...

But since you want to start with electronics

read Horowitz/Hill: The art of electronics (library?)

Now build your custom discrete transistor drivers...

You can also get LEDs that only draw 2mA. They are not so bright, but then you do not have to use a driver only a resistor

Which country do live in. I you live in Europe I might give you a vendor

I know Agilent has such a series of LED
