<div dir="ltr">Hi David,<div><br></div><div>Thanks for your response. I was able to get a little further and am now fairly confident that my declare function should look like:</div><div><br></div><div>Declare Function WritePortUSB Lib "cbw32.dll" Alias "cbDOut" (ByVal BoardNum&, ByVal PortNum&, ByVal DataValue%) As Long</div><div>(since per MCC documentation, the cbw32.dll file contains the "cbDOut" function for sending digital signals to the device)</div><div><br></div><div>and my inline commands (eg to send signal 16 to the device through port 1, with board set to 0 since when I open MCC's instacal program I see that the device is labeled as Board #0) as follows:</div><div><br></div><div>WritePortUSB 0, 1, 16<br></div><div><br></div><div>The script will compile and run with the declare function, but once i include the WritePortUSB line of code I get a "missing parameter" error from eprime.</div><div><br></div><div>Any idea what I might be missing here? I'm not sure particularly what number I should be using for PortNum, but I tried several values with the same result. </div><div><br></div><div>Thanks!!</div><div><br>Annchen</div><div><br></div><div><br>On Thursday, March 6, 2014 12:09:02 PM UTC-5, McFarlane, David wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Annchen,
<br>
<br>For the syntax & usage of the Declare statement, look at the Declare
<br>topic in the E-Basic Help facility. You might find even better
<br>documentation for Declare in references for Microsoft Visual Basic or
<br>Visual Basic for Applications.
<br>
<br>For the rest, you really do have to get that from MCC, they are
<br>supposed to know and document which of their .dll files and functions
<br>to use. As I recall when I used their UL (almost 4 years ago now),
<br>it came with extensive documentation and examples. Remember that
<br>E-Prime is just a derivative of MS VBA, so you should look at the
<br>documentation & examples for Visual Basic. In fact, next time you
<br>talk to MCC staff, do *not* mention E-Prime, just tell them you want
<br>to use their board with Visual Basic, and that should help orient them better.
<br>
<br>Best,

<br>>Come to think of it, there is a way to send & receive data through USB

<br>>
<br>>Recognizing that the MCC UL essentially just adds a DLL to provide the

<br>>
<br>>Mind you, I am not advising you do any of this. Just being an academic
