Re: USB TC-08 in python

Hello,

Here is some Python code to use Pico TC-08 USB with DLL in Python using usb_tc08_get_single.
tc08usb.py

TC08USB class should be improve to support other methods.

Kind regards

Hello, on a previous post you was talking of VISA drivers. On the other side (the hardware) I also wonder if you couldn't plan to have a SCPI parser on your devices. http://www.ivifoundation.org/specifications/default.aspx see SCPI 1999: SCPI-99.pdf http://en.wikipedia.org/wiki/Standard_Commands_for...

I'm sorry... I've now the hardware in my hand... but I still get an empty string....
I've change unit_info string size to "string_length" but it still fails !
I also change string_size from 0 to 256... the DLL call fails
If you have an example which is running fine I would be very interessted

Thanks for your reply... About passing struct to DLL in LabVIEW I found this... that could help you http://zone.ni.com/devzone/cda/epd/p/id/4489 http://zone.ni.com/reference/en-XX/help/371361E-01/lvexcodeconcepts/calling_external_apis I don't have enough time to dive into... so usb_get_formatted_inf...

Here is the 8.2 minimal sample for the get_unit_info problem. Kind regards Sebastien PS: if you are looking for nice LabVIEW drivers you should have a look at for example Agilent 34970A... on Devzone IDNET http://www.ni.com/devzone/idnet/f/ http://sine.ni.com/apps/utf8/niid_web_display.model_page?p_...

I'm sorry but I'm trying to get info using one of the following function - usb_get_unit_info I made a LabVIEW cluster (sort of struct) that could contain a USBTC08_INFO struct. I call the dll but my cluster still have "0" values - usb_get_formatted_info I thought that using this function could easie...

If you make an other VI sample you should hide the STOP/Abord general LabVIEW button using this http://zone.ni.com/reference/en-XX/help/371361A-01/lvdialog/cust_window_appearance_db/ So user can only use your STOP button that close connection with the hardware. The customer sample you provide me bef...

Thanks a lot... This vi is much cleaner than the other one ;-) But I say again that reusable vi are much better than samples... you say me to use open function twice... but is there a way to identify the unit because I have to measure 10 temperatures The 5 first one are measured using the first unit...

Hello, I'm sorry but you don't reply to one of my questions. How can I do (using only Labview) if a user click on the LabVIEW stop button instead of the main loop stop button ? I also have an other question... How can I do if I have 2 TC-08 ? Can I give USB TC-08 id to the open function ? Kind regards

I found some strange informations in your datasheet. tc_type Specifies what type of thermocouple is connected to this channel. Set to one of the following characters: 'B', 'E', 'J', 'K', 'N', 'R', 'S', 'T.' Use a space in quotes to disable the channel. Voltage readings can be obtained by passing 'X'...

If I stop using the Labview stop button (instead of the front panel stop button) I know that I won't be able to reconnect to TC-08... This is (in my mind) a problem. The only way to solve it is to use Pico software (which is not a good idea in my case... even deconnecting/reconnecting the device doe...

Sorry I forget to say you something else... on your usbtc08.vi sometimes (several times) I get the following error message "TC-08 Not Opened" Even if I unplug, connect the TC-08 it always fails... The only way to get the labview sample running again is to open PicoLog recorder (which doesn't found t...

Yes it will be very usefull to have such VIs because my full VI in which I have to insert 10 temperatures acquisitions (so 2 TC-08) is quite big (I can provide you if you are interessted) I also use a Labjack U12 board. They provide such VIs (you can download them to be inspired on their website) I'...
