I'm a bit of a novice when it comes to using drivers and function calls etc but I have modest requirements and I hope someone out there can help me.
I am trying to use the digital output on the device ADC-11 USB. Basically, all a want to be able to do is switch the digital ouptut on and off using a VB macro from excel.
I understand that the function needed is declared as:
Declare Function UsbAdc11SetDo Lib "usbadc11.dll'' (ByVal handle As Integer, ByVal do_value As Integer, ByVal doNo As Integer) As Integer
(or something along those lines)
But then I need to call it and set it to O or 1.
How do I do this.
I'm sure this is quite basic, but any help would be greatly appreciated (and, if not too cheeky, an example).
