It is possible to contact PCA9548A (8-CHANNEL I2C SWITCH) using USB-8451?

Hello

Now, I'm doing a project related to the smart battery. Now, I read data from a stack using the USB-8451 by smbus. The next step uses the USB-8451 casing to read the data of several batteries through smbus. I chose the PCA9548A (8-CHANNEL I2C SWITCH) to achieve this goal. But when I check the specification of the PCA9548A, there is a fix I2c format to read data from it, I tried several times, but still no can tell me where is the error in my code, or maybe it's impossible to communicate with this chip using USB-8451?

Here is the fix that i2c read format of PCA9548A

Why are you usng the script live? Have you looked at the examples of delivery for the 8451? You just need a couple of nodes property to set the rate and the address, and then use the VI to write I2C.

  • Is it possible to change the default channel strip settings?

    Is it possible to change the default channel strip without having to depend on models?

    For example, I always wish to have:

    • Follow the value Name = 3 lines instead of the default line 1.
    • 'Follow the icons' checkbox deselected
    • Always follow box color
    • Control surface Bars always deselected

    Stuff like that... This apples to any screen that is affected by the Configuration of channel strip window. (View mixer or titles).

    Thank you!

    Is it possible to change the default channel strip without having to depend on models?

    NO.

    But why not use a template? You use a template of this moment anyway, the default value of project. Just change and set the Start Action that you configured

  • Try to use the same pattern for more than two channels (CSR configuration) with usb 6000

    Hello

    I am currently trying to implement a LabView code to get readings of voltage using 5 different places at the same time. I want to only use the first location in the ground and get 4 measurements of voltage between the ground and each of the other 4 channels. I use a USB 6000 which, for now, allows me to use the same pattern for only two channels. Is it possible to use the same pattern for 4 channels?

    Thank you

    Maria

    The images do not explain everything. You must explain what are the sensors. I think you totally wrong on how they should be linked. CSR, all sensors must be a common understanding and the outputs not individual channels as I have already explained. If you are unable to do this, you should probably not use CSR and you have the wrong data acquisition device. If you want a side of a sensor as a reference, you need differential connections.

  • Hi I have a new Apple Watch - sport Strip. Is it possible to buy separately strips that can be used with the watch?

    Hi I got a new Apple Watch as a gift at Christmas - sport band, white, 42 mm. 7000 series. Since this is my first Apple Watch, I wonder if I should check all options at the store before opening the box. Is it possible to buy separately strips that can be used with the watch?  Thank you, in advance, for any advice, guidance, you can offer the wisdom.

    Hi, Kate

    Yes - any band Apple Watch 42 mm fits your Apple Watch.

    Non-Sport bands have different lengths, then check the circumference of your wrist and see Apple Watch Sizing Guide (that compares all the Apple strips) before you buy separate bands:

    http://www.Apple.com/shop/watch/Sizing-Guide

    Try them in an Apple Store, it's also a great option.

    The Sport of Apple Watch also has an anodized aluminum housing, while the non-sport bands have different metals of cards and/or links (this does not affect the compatibility, only appearance).

  • example 2-channel oscilloscope VI using real-world signals

    I'm looking for an 2 oscilloscope channels VI that uses real-world signals, not simulated signals used by "two Chennel Oscilloscope.vi' I found under examples when I searched"Scope"or"oscilloscope ".

    I found on a site OR "One_Channel_Simple_Scope.llb".  I think he uses real-world signals.  I downloaded it but not able to run the VI.  When I tried to do, it didn't compile successfully.  The error messages were several subVIs are not found: DAQmx read.vi, DAQmx timing.vi, etc.  I have LV 8.6 and NI 6221 Multifunction DAQ card, installed in a standard configutration in an environment of Winows Vista.  I define a variable say LV path where to find these screws?

    Thank you.

    Not a sampling frequency is high, but this uses entries of the sound card on L and R for 2 channels:

    Have you installed traditional data acquisition and not the more recent style DAQmx drivers? Maybe it's the source of your mistakes.

  • Suggestion: It's about the COPY PASTE function. It is possible to apply multiple copy and paste feature uses publishers or any application of MS?

    Suggestion: It's about the COPY PASTE function. It is possible to apply multiple copy and paste feature uses publishers or any application of MS? For example, I need to copy the 4 lines of text and want to paste in 4 different applications. First line on the 1st application, 2' nd on the other and so on. With this I can choose 1st line and COPY 1 copy, nd line 2' COPY 2 and so on. And while pasting, I can choose the necessary text to PASTE 1,2,3 or 4.
    This feature takes really where people have to work with text editors in their daily lives and find these scenarios quite often.
    I have no idea if this feature is already encapsulated in the MS Editors, so if it's already there kindly let me know.

    Thank you.

  • It s possible to create a Java plug-in to use BBM in a WebWork?

    Hello everyone.

    As the title suggests, "it s possible to create a Java plug-in to use BBM in a WebWork?

    I mean, the java extension BBM will work in a WebWork?

    Thank you

    According to this page, the BBM API for Java are in beta. It is also expressly stated that MDB widget will soon be available, and it was in October.

    It does not seem to be out yet. However, I think that you could develop your own Extension to expose the Beta SDK for use in javascript. There are around the resources to learn how to create your own extensions. This lab is the best.
