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?
[quote]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[/quote]There is no voltage output from the K8055 digital and PWM outputs. 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.
