K8055 Digital Output

First, I am sorry for my English.
I have k8055 board and I want to turn on LED from PC without other power supply,
Can I do that with demo program or I need built my program

You’ll find the +5V from the SK2 and SK3 on the K8055 board.
Connect the LED with a series resistor 1K from SK2 or SK3 to the digital output of the card.

I want to make 8 canal lightshow with triacs and I connected it on 8 outputs, when I go in demo and turn on digital output 1,2,3,4 or any other I just get red LED turned ON
Is this hardware issue or i should find other program?
And which program I can use for controlling K8055, I mean in which program I can put c or vb code?

These outputs are open collector NPN transistors. You have to use external voltage and add pull up resistors from the digital outputs to the external voltage.

[quote]And which program I can use for controlling K8055, I mean in which program I can put c or vb code?[/quote]Please download the latest software package for the K8055.
Here is the link to the download page:
velleman.eu/distributor/supp … code=K8055
Download the: “Complete SDK Pack (Rev 4.0)”.

The package includes new K8055D.DLL and sample projects written in various programming languages. - VB and C++ examples are included.
Pleas check also the “README.TXT” and the “K8055 & VM110 Getting Started.pdf”.

Yes you can do it without wires.
Are you use the wi-fi connection,blue tooth. And you can connect with the LED series.Suppose want to make 6 line lights you can connected it on 6 O/P lines. Get the output one by one 1,2,3 turn by LED.
