I have two k8055n and they function realy good alone, but i will use both of them to getter can you write me what the DDL(Visual Basic) is ? (I have adress it and when I change de number of the card adress in the program and resatrt it it works but not only still the programm works)
I need 5V on the digital outputs is that possible?? Where I need to put the 5V in?
Kind regards Nils Anderer
Auf Deutsch:
Ich möchte zwei K8055n betreiben, mein Problem ist das ich keine DDL finde mit der die zwei gleichzeitig angesteuert werden können.
Ich bräuchte 5v an den digitalen Ausgängen ist das machbar wo muss ich das Board mit 5v speisen?

Then use SetCurrentDevice to select the card you like to control and read.

[quote]2. I need 5V on the digital outputs is that possible?? Where I need to put the 5V in?[/quote]The digital outputs are open collector.
Add pull up resistor between the K8055N digital output and +5V of external supply (or +5V of the board).
You’ll find the +5V from the upper pin of SK2 and SK3 on the K8055N board.
Be careful - do not overload or short circuit this internal +5V supply !

[quote]I don’t now i have tried the SerachDevice() but i have not found the solution.
Where must i the SearchDevice() declare? And what is the first part(Private Sub Form1_Load)?[/quote]If you have cards coded to addresses 0 and 1, you can use this code to set the digital outputs on (Button1_Click) and then off (Button2_Click) for both of the cards:

[quote]And with the digital outputs i don’t understand it, because i’m not professional person, can you draw a schematic? I need 0V or 5V on the outputs and i can’t go over the ground because of the Motor Driver (Pololu A4988).[/quote]Here is how you can get 0V to 5V output:
