using several of the ADC (ad7476a) via SPI

Hello:

I BF537-EZkit and AD7476A-GERD and I set to work using the project "SPI and UART.

But in my project, I have to AD7576A several... How to configure the SPI to do this?

I used the "analog s in reading" loop inside the moment (who writes via UART), but he reads the ADC too slowly for the reading of the AC...

What is the correct way to do it? The UART is useless I use it just to see the values read by the ADC...

Thanks in advance,

Antonio Freitas Verissimo

Hello

To control the operation of the multiplexer, you can use a digital output of the Blackfin. You can use the PPI on the Blackfin to do. You will be able to control in LabVIEW with functions at Black fins that have been added to the palette for LabVIEW.
If you are not familiar with LabVIEW, you can learn here:

Besides, the exercises provided with the EZkit should help ( http://zone.ni.com/devzone/cda/tut/p/id/6949 ).

    I use to manage my DSL modem via an ip address. When I enter FF8 I wonder where to save the file. Why and how can I prevent the FF8 to do this?

    And now, whenever I'm in an ip address that I wonder if I want to download the file.

    This happens when the modem server does not send the file in text/html, but with a different MIME type.

    I tried adding index.html in the event that the server can send this file as text/html.

    Hello

    I have a sport IWatch found that domestic activity (usually running on treadmill) there is a huge different iWatch see the short distance (approximately 23%) then the treadmill Distance (I used several treadmills). Calibrate the iwatch outside.

    Hi Avner

    Currently, there is no way to calibrate Apple Watch on a treadmill.

    Calibration teaches your watch how your arm movements relate to your length of stride at different speeds when walking you and/or running. It does this by comparing the accelerometer data with GPS (location services) data from your iPhone. To optimize the performance of the application of the workout, when using the treadmill, allow your arms swinging naturally.

    It can help restore your calibration data and start over:

    On your iPhone, in the application of the watch, go to: My Watch (tab) > privacy > Motion & Fitness > tap reset Calibration data.

    To calibrate again, follow the instructions in the article to support below, including:

    • Records open-air market training and/or run in the open air with the application of the workout on your watch.
    • This for 20 minutes at each speed to during which normally walk you or run.
    • While doing so, take your iPhone with you, with location on Services.
    • Allow your arms swinging naturally during training.

    Estimates of activity also dependent on your personal information. To verify that it was entered correctly and update over time:

    -On your iPhone, in the application of Eve, go to: Watch My > health > edit (top-right).

  • don't forget the select result of a statement to be used several times in the procedure

    Hi all

    I'm sorry for this kind of question, I'm not newbie, but still need your help.

    My need is remember the select result of a statement to be used several times in the procedure.

    My first guess is to use a temporary table, but I think there's better decisions.

    For example, I should make a heavy request

    Select the code from table_function (param1)

    Then, this query is used to insert a list of the id in table1, delete table2 and update in table 3.

    Help me please do not use if possible temporary tables.

    If there is more than one column, you need to create an object type at the database level. Create a collection of this type of object in the procedure.

    Example:

    CREATE OR REPLACE TYPE "OBJ1" as OBJECT(
            column1 varchar2(256 CHAR),
            column2 varchar2(35 CHAR)
            );
    
    CREATE OR REPLACE TYPE "nt_obj1" as table of OBJ1; -- this could be done at procedure level as well
    
    DECLARE
       t_employee_ids   nt_obj1;
    BEGIN
       SELECT OBJ1(column1,column2)
         BULK COLLECT INTO  t_employee_ids
         FROM table1
        WHERE column3 = NNN
    .............

  • How to use several different sections of the same clip in the timeline?

    Hey, I used this tutorial as a reference for editing. I have my own equipment I want change, which includes several takes different. Is it possible to use several different sections of the same clip in the timeline? You know, like the good part of a certain record keeping. I appreciate any assistance. Thank you

    Post edited by: Kevin Monahan

    Reason: changed the title of best research opportunities

    I prefer to put the clip in the Source monitor Panel, then set the points and exit. From there you can simply drag the section of the element in the sequence.

    Or, you can make a subelement, the section will have a distinct element in the bins in the project Panel. You should always keep the original material, but now you can have real subitems to work if you prefer.

  • Using the web services via VBScript

    Hello

    I'm very big thing back to the VMware infrastructure.

    (1) in my application, I want to write a VBScript (preferebly) that can consume web services provided by ESX to clone the exsisting images and do some basic operations on, snapshot etc. as powern. Is this feasible?

    (2) according to my understanding, the services web of ESX and vSphere services are the same. Am I wrong?

    (3) services of vSphere web must vSphere is available in fact?

    Please forgive me if any of the issues makes no sense. Kindly guide me further.

    Hi Chaitanya,

    vSphere API provides a way to interface with VMware infrastructure, and these are exposed as services web servers ESX and virtual Center.

    (1) vSphere Web Services SDK facilitates the development of client applications that target the vSphere API. It allows to build SOAP-based applications to control the ESX Servers / vCenter servers and virtual machines running on them.

    You can write client applications in Java or c#. vSphere web services SDK includes files WSDL, examples of code in Java and c#, various libraries and all the necessary components required to work with the vSphere API.

    You can also use vSphere SDK for Perl which provides a script Perl to easy-to-use interface to the vSphere API. SDK comes with utilities and documentation for the creation of vSphere management applications

    (2) are you reason ESX web services are actually vSphere web services. vSphere is bascially the name given for the latest versions of 4.0. Earlier he was VI SDK 2.5/2.0 and now it's vSphere web services SDK.

    (3) vSphere web services are exposed in the ESX servers, so ultimately you need vSphere infrastructure on your side. What is it ask you?

    I hope this information helps!
