NXT-G block for HiTechnic Servo Controller

I'm trying to track down an NXT-G block for the HiTechnic Servo Controller. My son just purchased the controller at LEGO Ed but hasn't found a block for it. After a lot of searching, we did find a block for the HiTechnic DC Motor Controller ( http://joule.ni.com/nidu/cds/view/p/id/1129/lang/en ) and was hopeful that a similar block for the servo controller would be available somewhere. He has spent quite a few years working with RoboLab and NXT-G with LEGO robots and felt that the combination of the NXT, servo controller, and NXT-G 2.0 control and data logging would be perfect for his project.
Cheers!

Ok, I made a Sub VI with it, and put together a simple program. When I try to download it to my NXT, it gives me the error "Cannot open a VI because it is password protected."
Any idea on how to fix this?

Interfacing TETRIX/NXT HiTechnic Motor controller to myRIO

I am an Adjunct instructor at a Junior College.
We are implementing the Intelitek "Advanced Engineering with myRIO" curriculum.
This is a brand new program and we have received the software, course materials
and the myRIO controller but it will be close to mid term before we get the
rest of the hardware based on the TETRIX Prime robotic platform and interface
board.
I have borrowed an older TETRIX kit from a local High School that was used with
the LEGO NXT and it hast the HiTechnic Motor controller with the NXT connector
interface.
What I am wanting to do to get the student started (we just had the 2nd week
meeting of a 14 week course) is take the motor controller with the NXT cable
and interface it to the I2C interface on the myRIO.
I had found online a German site that has a board that will directly connect
the NXT sensors to a myRIO.
I was wondering if you have any VIs that might help met get this working
quickly, even the code details from the NXT version of Labview for the Tetrix
controllers would probably help.
Thanks in advance
Scott Willis

Hi Swillis,
Unfortunately we do not have an specific library to communicate with the Tetrix controllers. The following link, contains information related to the NI LabVIEW Module for LEGO® MINDSTORMS®, but it is not supported and will not necessarily work fine for the myRIO programming.

NXT Custom Block Development with LabVIEW 8.2.1?

I'm trying to develop a custom NXT block using
LabVIEW 8.2.1. Is this possible? I am having trouble importing the finished block into
the Mindstorm environment. My block is always greyed out in the import
list. My block seems to compile just fine. In fact, if I create a new
example block from a template and try to import that without
modifications, I get the same behavoir.
Any ideas on how I can debug this?
P.S. Hopefully this actually goes to the LabVIEW Friends of LEGO group ; )

Eagles Coach is right on the money here. Because the MINDSTORMS environment is built on LabVIEW 7.1, that's the only version you can use to create custom blocks for the environment. LabVIEW 8.0 and 8.2 are useful if you plan to do all your programming in LabVIEW itself, but won't help you create blocks for MINDSTORMS.
You could use the "Save for Previous" feature of LabVIEW to backport your code to 7.1, but that would require you to have both LV 8.0 and LV 7.1.

Scanning mirror using Thorlabs TDC001 apt-dc servo controller

Hello. I need help with configuring a Labview code controlling a Thorlabs TDC001 apt-dc servo controller. I just need direction on which commands to use to input the parameters of the distance and repetition rate of the stage that the controller is linked to. Attached are two separate codes that myself and a colleague created for the stage. If someome can look at this and offer some helpful tips, that would be appreciated. I am now learning how to use Labview correctly.

Hi opticsdude,
I would recommend taking a look at motion examples in the NI Example Finder (you can find this by going to Help>Find Examples in LV).
You can also take a look at the NI Motion Help here. There is also a good article on motion control in general here with lots of related links that you might find useful.

Can LabView 2013 be used to develop blocks for Lego LabView Education EV3?

I would like to interface some custom sensors to the Lego EV3 brick. Can LabView 2013 be used to build Blocks for Lego LabView EV3 software?

Please note Mac OSX users using LabView 2013 Student Edition -- you CAN use the new EV3 modules but you must install f1 patch first.
I installed NI LabVIEW 2013 LEGO MINDSTORMS NXT Module f1 Patch.
Then
NI LabVIEW 2013 Module for LEGO MINDSTORMS f2 Patch
Now I can program for LEGO EV3, download to EV3 and it works all from the LV 2013 Student Edition (UK).

Petalinux driver problem for AXI Interrupt Controller on Zynq

We are trying to use the AXI interrupt controller because we have more than 16 uarts. We are running Petalinux 2013.10 and the device tree is attached.
When a UART is connected directly without using the AXI interrupt controller it seems to work as expected; the interrupt fires and all data gets through at any baud rate. However, if the interrupt is going through the AXI interrupt controller the interrupt fires but we consistently get an overrun if we send more than 16 bytes at 115200 baud. Note that this is when there is only data on that one port. This would seem to imply that the interrupt is taking so long that the UART buffer overflows.
The kernel output (attached) says that all the uarts going through interrupt controllers (uarts 1-32) are on IRQ 0, which seems wrong. I would expect a different IRQ number for each of the two AXI interrupt controllers.
From this forum post, it looks like the driver is meant for microblaze but they got it working on Zynq:
http://forums.xilinx.com/t5/Embedded-Linux/Petalinux-driver-for-AXI-Interrupt-Controller-core/m-p/525305#M10742
Unfortunately they didn't specify what they did to get it working.
Has anyone successfully used the AXI Interrupt Controller on a Zynq or other non-microblaze architecture?
Thanks,
Jaymes

I really appreciate your help. I'm getting closer to a solution.
I ORed all 33 of our interrupts together using a utility logic block. I added interrupt settings to each uart device tree entry:
interrupt-parent = <&ps7_scugic_0>;
interrupts = <0 57 4>;
This results in all uarts at IRQ 89, which I think is correct. I also tried interrupts = <1 73 4> with the same result.
It seems that all uarts are responding to interrupts, but only the last (33rd) uart is generating interrupts. If I try to send/receive data on any uart other than 33 it won't be sent/received until there is activity on uart 33. Any ideas?

Further the kernel driver needs to have IRQF_SHARED defined and some other fixes as discussed int this issue:

This is supported with an "IRQ sharing" kernel option in the 16550 uart driver.

Incoming orders in COPA not working if Sales Order blocked for Credit Check

Hi all,
We need to build a report showing all incoming sales order by entry date and/or change date (change of values or quantities later on). COPA allows to do this, but the problem is that COPA line item table is only updated if the sales order is released from credit check (VKM3). I am looking for a solution to be able to record sales orders in COPA even if they are still blocked for credit check. By doing that we will be able to report all sales orders entered from COPA and provide basis for commissions calculation to the business.
I have investigated possible COPA enhancements like COPA0005 but it doesn't seem to be used at the time of sales order save.
Thanks.

Hello ,
Thanks for the reply
As you said , the credit check in the service order is information message "Credit check (maximum percentage for ope
exceeded)" .
If you enter and come out this message then one more message will come , i.e., "The business transaction can not be carried out" detail message - System status CNOK is active (ORD XXXXXXX).
with the above message , system will not allow to do the Service order release.
In this particular case , we have done the VKM1 for the sales order to unblock the order from credit check . But again system is checking the credit check at service order (created w.r.t sales order) . we are not able to control this .
we also suggested the solution to the customer , saying removal of credit check for service orders . But customer requires credit check to happen at both the documents.

Credit Block for released sales order

Dear All,
I have got one issue. There is a sales order which was created earlier say 15 days back. It went into the credit block at the time of saving it. It was released through VKM3 too.
Now when i change any field in the sales order today, it is going into the credit block. We are not changing any value of any of the item. Just maintaining the Billing block in it or remobving the Billing block.
The number of days maintained in the OVA8 are 182. So as per the standard functionality it should not go into the credit block for any change in the sales order like changing the billling date or changing the billing block.
Can you please let me know what might be the reason for this sales order to go into the credit block..??? Any help is very much appreciated.
Thanks and regards,
Vishi.

Dear Vishi
Please check if you have checked the critical fields option.
Credit check against critical fields (fixed value dates)
The indicator controls the critical field check. If the field is selected, the system checks whether critical fields have been changed.
Use
If a check is carried out, the following fields are relevant:
Payment terms
Additional value days
Fixed value date
Note
Use this type of check for sales documents only.

Credit block for Slaes Order on Days Basis

Hi SAP Gurus,
As my client requirement want Credit block for sales order with days basis.For example Customer has credit 5000 and 30 days.Even credit value not exceed on 31st day, But sales order has to block .
Please requesting to all kindly needful for me.

Hi
Check payment terms in Customer master data, billing tab page. We can define payment terms. And if you want to block the customer use dynamic credit check.
Enter 5,000/- in maximum document value in FD32
For Credit management to be working
1. In def of SD type we need to speciy Automatic credit control in the field " Check Credit Limit"
2. In the defination of corresponding item category we have to check the field "Credit Active".

Release Orders Blocked for Delivery

Hello Experts!!
We have V.23, release orders blocked for billing.. is there a similar transaction where we can release orders blocked for delivery??
Help is greatly appreciated.

Hello Carla,
Yes in the T-code "V.23", you can release the billing block for SALES ORDER in one single click. While releasing the delivery block for the Sales order the following T-code are useful:
1. VDBLOCK
2. V.14
3. VA14L
When you are using these T-codes, you get the list of all the Sales order which are blocked for Delivery. Then you can select the document for which you want to remove the delivery block and do the required updation.

SARTHAK

Schedule line blocked for delivery

Hi Friends,
Can you please tell what does Schedule line blocked for delivery ( LIFSP ) means?can you please explain the business process involved in this?
Regards.
Dinesh

At schedule line level, the following are some important prerequisites must be fulfilled, else the same would be set as blocked:
1. The schedule line must be due for shipping on the specified selection date.
2. The schedule line is due for shipping as the material availability date or the transportation scheduling date is reached.
3. The schedule line is not blocked for delivery.
4. The delivery quantity must be greater than one.
5. The items in the order must be fully processed.
6. The product status of the material must permit delivery.
7. No credit check are pending.

Driver for the ethernet controller on a HP Pavillion P600000 Series desktop after upgrading to Windows 7 Enterprise?

After upgrading from Windows 7 Home Premium to Windows 7 Enterprise (x64) Service Pack 1 (build 7601), I cannot find working drivers for my ethernet controller. The desktop is a HP Pavillion, Model
No. p6710f. I located the drivers on HP's website, but Windows 7 Enterprise
is not listed as compatible. Compatibility list:
Microsoft Windows 7 Home Basic (64-bit), Microsoft Windows 7 Home Premium (64-bit), Microsoft Windows 7 Professional (64-bit), Microsoft Windows 7 Ultimate (64-bit), Microsoft Windows 7 (64-bit)
The original driver (according to HP's site) is a Realtek PCIe Family networking controller, Version:7.26.902.2010 Rev. A.
I tried contacting HP, but apparently I voided their warranty once I upgraded to Windows 7 Enterprise. I do not have a support plan with Microsoft because the operating system was purchase through TechSoup (nonprofit). I greatly appreciate your help;
let me know if you need more information.

Windows 7 Ultimate and Enterprise are essentially the same with regard
to their software. Only the license is different. So if it's
compatible with Ultimate, it's also compatible with Enterprise.
