USB port TMS

Fri Mar 7 18:59:52 UTC 2014

Hi David,

Thanks for your response.  I was able to get a little further and am now 
fairly confident that my declare function should look like:

Declare Function WritePortUSB Lib "cbw32.dll" Alias "cbDOut" (ByVal 
BoardNum&, ByVal PortNum&, ByVal DataValue%) As Long
(since per MCC documentation, the cbw32.dll file contains the "cbDOut" 
function for sending digital signals to the device)

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:

WritePortUSB 0, 1, 16

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.

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. 

Thanks!!

Annchen
