Dual spi device with one master and one slave on the PC end

The powers that be want to emulate a hight speed RS-232 connection to an instrument we are building. We don't want to poll the instrument to see if it has data. They want the instrument to have both master and slave SPI busses so that it can push data to us.
I need to find the PC hardware to do this that is compatable with LabView so I can test it. It doesn't have to be a single device. It could be two as long as one can be master and the other slave. We have the NI USB-8452 but it can't be slave.

Hi Viper
You are right, the 8451 can only be configured as an SPI Master. For creating a slave you would have to choose an FPGA based solution. Depending on the hardware from NI that you currently have, you can choose from different FPGA cards or devices. I found some links that might help you with your search:
Community: SPI Slave Device in FPGA
White Paper: Implementing SPI Communication Protocol in LabVIEW FPGA
Forums: Slave SPI product recomendation
Forum: SPI in FPGA Multifunctional card discussion
White Paper: SPI and LV basics (check section 7)
Hope the information provided is helpful.

Hi,
You do not need to mount a screen. Just add a new region with several text fields inside. You should fetch a row by a process and populate the set when you load the page or click on a button. Insert, update, and delete should be done by processes. You have to have Next and Previous buttons to brows trough all rows of the detail table.
The most important thing here is what the connections between tables in your database are.
If they are the "One to many, One to one" you can use the approach described above.
If they are "One to many, One to many" will be better to use buttons or links to lunch details' tables in separate forms.
If the second and third tables are connected only to the master table you can use two buttons at the right of every master row. Clicking on the buttons will bring separate form for each detail table.
If the third table is just a luckup table to the second one you can use "Select List" field into tabular form of the second table in one Master-Detail form.

Can I backup two devices (with different documents) to one iCloud account? For example: iPad and iPhone, not everything is synced between the two, but I would like to backup each (seperately in the cloud), is this possible?

Hello Apple Community,
Can I backup two devices (with different documents) to one iCloud account?
For example: iPad Air and iPhone 5, not everything is synced between the two, but I would like to backup each (seperately in the cloud). Is this possible?
This way when I change from an old ipad to a new, I can restore with the ipad backup, and when I change from an old iphone to a new, I can restore from the
iphone backup.
Thank you in advance!

Terminology check here. Do you really mean a "CD"? There's a difference in Cloud behavior between content from a physical CD you ripped (which only has Cloud content if you have iTunes Match) and an "album" you bought from the iTunes Store.
Read references for Home Sharing.
iTunes: How to share music and video - http://support.apple.com/kb/HT2688 - about Music Sharing and Home Sharing
Home Sharing Support page - http://www.apple.com/support/homesharing/
iOS: Setting up Home Sharing on your device - http://support.apple.com/kb/ht4557 - "With Home Sharing in iOS 4.3 or later, you can stream your entire iTunes library over your home Wi-Fi network from your Mac or PC right to your iPhone, iPad, or iPod touch."
The above can get pretty complicated. You are probably best off by syncing both devices to a single library and/or updating the libraries on both computers to have the same content.

ADF BC - One Master and Two Detail pages How To?

I have an existing ADF BC .jspx master-detail page that works fine. It shows one product as the master (read-only; no navigation controls) and assocatied customer feedback as the detail (multiple records; read-only.) Now I also want to compute some averages from the same table used to create the detail view object. I have created a second view object because this requires a separate query that calculates aggregate values. I want to take advantage of using view links so that this 2nd view object is automatically linked to the master record via the primary key.
My question is how can I link this into the existing master-detail data control so that I can drag/drop it to include id on the existing .jspx page and the primary key linkages will be handled automatically?
Tables
Product
Feedback
View Objects
ProductView
FeedbackView
FeedbackAVGView
Current ViewLink
ProductFeedbackViewLink = ProductView + FeedbackView
Current DataControl
ProductFeedbackViewLink-Instance
Data Control is displayed on .jspx page; want to also include 3rd View Object, FeedbackAVGView, in the Master-Detail relationship and display on the .jspx page

Thanks for the reply. The existing customer feedback view object displays the customer's text feedback (testimonials) - these will be displayed in a read-only table with multiple records.
The new view object aggregates the ratings score from the customer feedback (same FEEDBACK database table) and will use a form to display the results (not multiple rows.) The PK is included in the aggregate view object query.
Note there is already an existing viewlink between the PK (Master) and FK (Feedback) - in the data control, this viewlink is an instance of the Master View Object and the Customer Feedback View object. Now that I have created a third view object, should I create another View Link between the Master View Object and the Customer Feedback AVERAGES View Object? If I do this, how do I include it in the existing .jspx page? If I add this new View Link to the Application Module I will have two different Data Controls:
Data Control #1: Master (Product) View Object + Customer Feedback View Object #1 (implemented as a master-detail read-only form/table on a .jspx page)
Data Control #2: Master (Product) View Object + Customer Feedback AVG View Object #2
I'm confused as to how to integrate the second customer feedback view object into the existing Data Control / Master-Detail read-only form/table on my .jspx page?
thanks

Each device only syncs waht you select.
Select only what you want for each phone.

I have 2 macbooks each with an account for me and one for my wife. I use one Macbook logged in with my account and my wife uses the other Macbook only loged in on her account. We both make regular time-machine back-ups each on a separate external disk

I have 2 Macbooks each with an account for me and one for my wife. I use one Macbook logged in with my account and my wife uses the other Macbook only logged in on her account. We both make regular time-machine back-ups each on a separate external disk. Is it possible to update her account on my macbook using her external disk without overwriting my stuff on the same Macbook and vice versa?

Time Machine does not do individual accounts. It records the complete drive. So if you were to use her TM backup on your Mac it would make your Mac just like hers. Both yours and her account on your MAC.
Just copy the missing files over from her Mac to yours. If there are differennt programs on each then they would need to be installed on both.

I am fed up with Spring and Apple passing me off to one another and neither will fix the problem. I am unable to receive a connection on my phone.

I am fed up with Spring and Apple passing me off to one another and neither will fix the problem. I am unable to receive a connection on my phone.
The internet goes out and I have to reset network setting each and every time. This is only a temporary solution which by the time I release the line with Spring or leave the apple store the issue is back. Sprint indicates that it is a know issue with the Iphone 5 and apple says it is a network issue as Sprint's network is not up to par with the Iphone and can not meet the expectations on the Iphone 5.
I have attached a few picture, as you can see it clearly says I have 5 bars and 3g available but I have no connections what so ever.
This issue affects all data and so I can not send or receive picture messages, use apps, or access the internet. The data goes in and out intermittently and it seems the phone chooses what I can and can't do.
For example I can watch Youtube or Vevo videos but I can not access Facebook or Instagram.
Is anyone else having this issue?
I will soon loose my patience....
I have reset my phone three time and have reset network and other setting mutltiple times.

Any ideas cos its frustrating that I can't access something I paid for!

Sign out of the account you do not wish to use, sign into the one that you do wish to use.

I think you are using the same Composition Class on both project. On the properties tab, you can change this number (e.g.: EDGE-1637270).

Can't add a goods-issue with more than one item and one is serial managed.

Hi,
We are trying to issue more than one item to a production order using the DI API. If none of the items is serial managed, they all are accepted and the goods-issue Add is successful. If one the items is batch-managed, the goods-issue Add is also successful. I am able to add the goods-receipt if I it contains only one item and it is serial-number managed. However, if Im issuing more than one item and one or more of the items is serial number managed, then the DI API will not add the goods-issue. The error message that appears refers to an item that is not among the items being issued. The message is:
-10: (IGE1.WhsCode)(line: 3), Item A00006        with system serial 1 is not in stock.
Again item A00006 is not even in the group of items being issued.
The code I am using for the serial number part is:
With oGoodsIssue.Lines.SerialNumbers
          .SystemSerialNumber = rs.Fields.Item("SysSerial").Value
          .ManufacturerSerialNumber = rs.Fields.Item("MfrSN").Value
          .InternalSerialNumber = rs.Fields.Item("IntrSerial").Value
          .SetCurrentLine(n)
          .Add()
          rs.MoveNext()
          n += 1
End With
The rs is a recordset that the code is looping through as the serial numbers are being added.
The error message does not occur during this code. It occurs when it tries to add the full goods-receipt. Does anyone have any idea how I can fix this?
Thanks,
Mike

Hi Mike,
Try to do the ".Add" only if you need it. Doing a ".add" without assignation may cause the error you have.
I guess your n variable start at 1 or 0, so you could put code like this :
With oGoodsIssue.Lines.SerialNumbers
if n = 0 then (or 1, also I don't the correct syntax of your programming language)
.Add()
end if
.SystemSerialNumber = rs.Fields.Item("SysSerial").Value
.ManufacturerSerialNumber = rs.Fields.Item("MfrSN").Value
.InternalSerialNumber = rs.Fields.Item("IntrSerial").Value
.SetCurrentLine(n)
rs.MoveNext()
n += 1
End With

You cannot.

I have applesauce with my apple products! I think I must have a different id and password with each one - Mac, iPad, iPhone - how can I change each one to just one ID and one password?

Oh my what a mess! I would really like to have one id and one password for all the products - MacBook Pro, iPad, iPod and iPhone. I am forever getting invalid id or invalid passwod message when I try to do something. The security questions are questions I never would have answered and I think the emails are going to my huspand's gmail account!
Can anyone help me sort this mess out?
This has been posted in the mac community as well!

If you want to merge Apple ID's - you can't do that. For reasons unknown, Apple just doesn't allow it. Passwords are are different story. You should be able to reset your password for any other the ID's that you have.
Do you have multiple Apple ID's? And if this situation is that much of a mess, you might be better off contacting Apple in order to get it straightened out.
Here is a user tip that might be of some help.
