 |
|
Hi,
I'm trying o write my software for an ADC212 starting from your examples. When I try to run it, I get a message like this: "An exception occured within the external code called by a Call Library Node ...".
My adc212 is conected to a laptop computer that doesn't have LPT's, therefore I use a Pico USB-PP connector. MAX finds only 3 COMs, I don't know how to identify my usb-pp port. It also cannot identify my adc212. The picoscope software works well, therefore the problem might be in LabView or inside the adc200.vi that I try to run.
Can anyone help me make that example start?
Thank you,
Florin

Hello Florin,
You will need to delcare the port as 101, 102, 103 etc when using the USB parallel port adapter.
Ensure you have installed the correct drivers for the USB adapter.
Best regards,
Michael

Hi,
I'm a begginer too  and I'm using a PICO USB-PP addapter.
Go to the front panel of the example, right click on the ports controller and sellect "find terminal". this will take you to the block diagram, at the routine that manages the ports reading.
Unwire your LPT ports terminal (as you don't need them) and wire a numeric constant instead. (I used 101 and it worked).
Please let me know what you got.
Regards,
Florin
