Test and Measurement Forum

I have developed a macro for collecting data and entering the data into columns and rows. This is based heavily upon the sample code.

The first run of the device works flawlessly, I can open the device set up all the parameters and then collect my data and close the device.

If I attempt to run the command a second time, the macro crashes at the set_trigger function, the function never returns a value, excel just crashes.

I can run set trigger multiple times in the first runthrough, I just can't run the macro a second time through.

Any Ideas?

Hi have you called the close unit function before it exits the macros?

Kind regards

Yes, I have called the close function.

The device is reopened with out any trouble, and I can set up the channels on the second runthrough, just not the trigger.

It could possibly be that the unit has not closed as the device was still doing some work, try calling the stop function, before the close unit to see if this helps. What product are you using by the way?

Kind regards

I have a 2205. And i did use the stop function.

I have included an example code which always crashes on mine. Debugging it shows that it will crash on the second set_trigger.

Code: Select all

Sub CauseCrash()


ps2000_handle = ps2000_open_unit()
   
 
  Call ps2000_set_ets(ps2000_handle, 0, 0, 0)
  Call ps2000_set_channel(ps2000_handle, 0, 1, 1, 5)
  Call ps2000_set_channel(ps2000_handle, 1, 0, 0, 4)
   
'This trigger set up works perfectly
 
  Call ps2000_set_trigger2(ps2000_handle, 0, trigger, 0, 0, timeout_ms)
 
  Call ps2000_stop(ps2000_handle)
  Call ps2000_close_unit(ps2000_handle)
   
'If I manually restart excel here, I can run the the code twice. 
'2nd run though
ps2000_handle = ps2000_open_unit()

 
  Call ps2000_set_ets(ps2000_handle, 0, 0, 0)
  Call ps2000_set_channel(ps2000_handle, 0, 1, 1, 5)
  Call ps2000_set_channel(ps2000_handle, 1, 0, 0, 4)
   
'This causes a crash, although it worked fine the first time it was opened
 
  Call ps2000_set_trigger2(ps2000_handle, 0, trigger, 0, 0, timeout_ms)
 
  Call ps2000_stop(ps2000_handle)
  Call ps2000_close_unit(ps2000_handle)
End Sub


This happens using both set_trigger and set_trigger2.

Hi Adam,

One of our software engineers has tried this without incident What driver version are you using?

Kind regards

This could be an issue. I was using 2.0.5.5 from the r1.0 sdk. and now I see that it has been outdated for a while.


I will try the new sdk release and get back to you.

Updating the driver and dll file appears to have fixed my issue.

Thanks for you help.
