<div dir="ltr">Hi everyone,<div><br></div><div>I've been referring to this older post for help getting E-prime to send output signals to a USB device: MCC USB-1208FS. Since Eprime doesn't have any native functionality for communicating with a USB I'd like to try using the DLL the comes with the device's "Universal Library" installation as David suggests below. However, I can't find any instructions for working with Eprime anywhere in the UL documentation (and the rep I chatted with at MCC help had never heard of Eprime), so I'm hoping that someone might be able to clarify two things for me:</div><div><br></div><div>1) Which MCC DLL file to I link to in Eprime? (and what is the syntax of the Declare statement?) The MCC rep said I should use cbw64.dll, but I'm not sure if he's right since he didn't really know what I was talking about</div><div>2) What inline commands then do I use in Eprime to send the signal to the USB? We had previously used WritePort with a different device that's been replaced with this USB</div><div><br></div><div>Thanks!</div><div><br></div><div>Annchen Knodt</div><div><br></div><br>On Monday, May 31, 2010 6:20:18 PM UTC-4, David McFarlane wrote:<blockquote class="gmail_quote" style="margin: 0;margin-left: 0.8ex;border-left: 1px #ccc solid;padding-left: 1ex;">Sara,<p>Come to think of it, there is a way to send & receive data through USB <br>using E-Prime, in fact I am doing that for a project now. First go to <br>Measurement Computing (referred to earlier) and get whatever I/O board <br>suits your fancy, e.g., their USB-1024 ($100). When that arrives, <br>install the Universal Libray software that comes with it. Then add the <br>appropriate Declare statements in the User Script area of your EP <br>program (see instructions that come with the MCC UL). Now you can use <br>MCC UL function calls from EP inline code to send & receive data through <br>the USB port.</p><p>Recognizing that the MCC UL essentially just adds a DLL to provide the <br>USB support, with enough ingenuity you could take this even further by <br>writing your own DLL to use from EP. For that, you might want to take a <br>look at "USB Complete" by Jan Axelson.</p><p>Mind you, I am not advising you do any of this. Just being an academic <br>and pointing out the full range of possibilities.</p><p>-- David McFarlane, Professional Faultfinder</p><p><br>David McFarlane wrote:<br>> Sara,<br>> <br>> Stock reminder: 1) I do not work for PST. 2) PST's trained staff <br>> really does like to take any and all questions at <br>> <a href="http://support.pstnet.com/e%2Dprime/support/login.asp" target="_blank" onmousedown="this.href='http://www.google.com/url?q\75http%3A%2F%2Fsupport.pstnet.com%2Fe%252Dprime%2Fsupport%2Flogin.asp\46sa\75D\46sntz\0751\46usg\75AFQjCNGivKXvQfxYcucJztVk4KS8DCk8jQ';return true;" onclick="this.href='http://www.google.com/url?q\75http%3A%2F%2Fsupport.pstnet.com%2Fe%252Dprime%2Fsupport%2Flogin.asp\46sa\75D\46sntz\0751\46usg\75AFQjCNGivKXvQfxYcucJztVk4KS8DCk8jQ';return true;">http://support.pstnet.com/e%<wbr>2Dprime/support/login.asp</a> , and they strive <br>> to respond to all requests in 24-48 hours -- this is pretty much their <br>> substitute for proper documentation, so make full use of it. 3) If you <br>> do get an answer from PST Web Support, please extend the courtesy of <br>> posting their reply back here for the sake of others.<br>> <br>> That said, here is my take ...<br>> <br>> Unless PST has added something new to the latest release of EP2, E-Prime <br>> simply has no facility for sending or receiving data through a USB port, <br>> so you are just out of luck there.
