Have anyone used Labview to call MSP430_Memory function in the MSP430.dll?

Hi,
I am trying to read data from Infromation Memory of a MSP430 MCU. I am using MPS-FET430UIF to communicate with the MCU and having trouble to get data using the function MSP430_Memory. Have anyone done this before? I greatly appreciate any help from this forum.

Good Afternoon,
I just have a couple of quick questions for you:
How are you going about calling the dll in LabVIEW?
Are you using the call library function node?
Could you post your code so we can take a look at it and get a better idea how you are going about it?
I hope you have a great rest of the day!

How to implement a callback function using LabView's Call Library Function Node?

I am trying to call a fuction from a SDK.dll library using the Call Library Function Node. The SDK was provided to
me and I do not have the source code, just the .dll and .h files.
The SdkSetPropertyEventHandler function has a callback fuction as one of its parameters. How do I implement the
callback using the CLF node? I am a good LabView programmer but this is my first time using the Call Library
Function Node. I have read all the info I can find on NI's web site and the discussion board but cannot figure
this one out. I am using LabView 8.6.
The SDK.h deacribes the function as:
// Function:   SdkSetPropertyEventHandler
SdkError SDKAPI SdkSetPropertyEventHandler(
            SdkCameraRef                    inCameraRef,
            SdkPropertyEvent                inEvnet,
            SdkPropertyEventHandler         inPropertyEventHandler,
            SdkVoid*                        inContext );
// Description:
//       Registers a callback function for receiving status
//          change notification events for property states on a camera.
// Parameters:
//       In:    inCameraRef - Designate the camera object.
//              inEvent - Designate one or all events to be supplemented.
//              inPropertyEventHandler - Designate the pointer to the callback
//                      function for receiving property-related camera events.
//              inContext - Designate application information to be passed by
//                      means of the callback function. Any data needed for
//                      your application can be passed.
//      Out:    None
// Returns:    Any of the sdk errors.
A separate header file called SDKTypes.h contains the following data:
typedef SdkUInt32 SdkPropertyEvent;
typedef SdkUInt32 SdkPropertyID;
typedef void       SdkVoid;
typedef struct __SdkObject*    SdkBaseRef;
typedef SdkBaseRef    SdkCameraRef;
SdkPropertyEventHandler
typedef SdkError ( SDKCALLBACK *SdkPropertyEventHandler )(
                    SdkPropertyEvent        inEvent,
                    SdkPropertyID           inPropertyID,
                    SdkUInt32               inParam,
                    SdkVoid *               inContext );
Thanks for your help.

Basically you do not do that. LabVIEW does not know pointers and certainly not function pointers. What you should do instead is writing a C DLL that implements the callback and also exports a function to be called by LabVIEW that translates between the callback and a LabVIEW user event. Look for PostLVUserEvent() here on the NI site to find examples how to do that.

Calling a Function node in a DLL to give force-feedback effect to a joystick (using DirectInput)

Hello,
I have been working for a couple of weeks on writing a DLL in Visual C++ Studio. My intention is to write an exported function in the DLL to initialize a Logitech Force3Dpro joystick, setup a force feedback effect and run it using DirectInput. I would like to control this force feedback effect (in particular, the intensity of the feedback) from Labview by calling the function in the DLL.
I followed the FFConst example in Microsoft SDK DirectInput Samples for making an .exe file to setup and run force feedback effects. I have been able to build the DLL successfully with an exported function that can be accessed from Labview by "Call a function node". I tested the function by running simple functions such as addition and multiplication of integers, andconfirmed the fact that the DLL was built correctly. I have also included the DirectInput code for initializing and running the force feedback effect. I am able to compile and build the DLL with no problems.
The Problem:
The only problem that I have at this point is with setting SetCooperativeLevel for the DirectInput8 joystick device. I have to provide a top-level window handle to SetCooperativeLevel so that I can give the function exclusive access to the joystick. Since I am not making a window and am building a DLL, I am not sure what handle I am supposed to provide it so that the joystick can respond. I am not sure if passing a handle to the Labview window would work because it is accessing the DLL's function? I tried passing LabView window handle to the function and read the X-axisposition off the joystick, but it read some junk (huge long integer) - which lead me to believe that the problem is something to do with initializing the joystick.
For all practical purposes, I am a complete novice at DirectInput
programming and working with Visual C++. Although, I have programmed in
C++previously. I am sorry for the long message, but I wanted to give a bit of background so that my aim is clear.
Any help, advice or direction with this problem be very much appreciated. Thank you for your time!
Cheers!
Abhishek

Hi,
This gave me the nudge in the right direction I needed, after a bit of basic frameset research I've got the desired functionality.
Huge thanks!

Do I have to use LabVIEW Real Time with a reflective memory node?

For reference with an external data system that will be temporarily installed at a customer's site, they have asked that I tie into their data network to record data from their control system. They apparently use a reflective memory network for data sharing. I have no prior experience with reflective memory, but all references to it involve real time systems. I do not need absolute determinism to acquire this data, I can be late by several milliseconds with no problem. Do I still need to use LabVIEW Real Time to interface with the PXI reflective memory node?

Hi AEI,
I have worked with that card briefly before. It has a Visa based driver and RT isn't required. However, I haven't worked with the card on a non-rt system and am not sure if there any issues to be aware of.
A lot of work has gone into integrating support for the card into Veristand, it may save you enough development time to use at an RT-Veristand system to be worth the extra cost.

Calling a Function in the Parent Window from the Child Window

QUESTION: How do I call a function resident in the parent
window from a child window?
BACKGROUND
I have a JavaScript function resident in the parent window
that reformats information obtained from the Date object and writes
the result to the parent window using the document.write( ) method.
I would like to call this function from the child window and have
it write to the child window instead. Is this possible? If not,
must I rewrite the entire function and nest it in the below code?
If so, what is the proper form of nesting?
CODE: The code that creates and fills the child window is
provided below. The highlighted area indicates where I would like
to enter the information from the function resident in the parent
window. I have tried every imaginable permutation of code that I
can imagine and nearly destroyed my parent document in the process.
I am very happy that I had a back-up copy!
function openCitationWindow() {
ciDow = window.open("", "", "width=450, height=175, top=300,
left=300");
ciDow.document.write("A proper way to cite a passage of text
on this page:<br /><br />Stegemann, R. A. 2000.
<cite>Imagine: Bridging a Historical Gap</cite>. " +
document.title + ". [<a href='" + location.href + "'
target='_blank'>online book</a>] <" + location.href
+ "> (");
MISSING CODE;
ciDow.document.write(").<br /><br /><input
type='button' value='Close Window' onclick='window.close()'>");
ciDow.focus();

Never mind - I was doing something very stupid and wasn't
calling the function as a method of a movie clip. I was simply
calling checkTarget(event) rather than
event.currentTarget.checkTarget(event); which seems to work.

Can call a function in the select statement?

Is there any ways to call a function in the select statement?
what I like to do is this:
select deptno, totalEmployees(deptno), TotalSalary(deptno)
from emp;
I know it can be done by count(*) and join tables, but my case
is much more complex and the where clauses are different from
one function to another, and have many tables to join and many
combinations
Thanks

Functions can be used in a select statement subject to certain
restrictions, see
http://otn.oracle.com/docs/products/oracle8i/doc_library/817_doc/
server.817/a85397/statem9b.htm#2062024
It's under "CREATE FUNCTION> Keywords and Parameters> function>
Restrictions on User-Defined Functions"
Here is an except...
When a function is called from within a query or DML statement,
the function cannot:
a) Have OUT or IN OUT parameters
b) Commit or roll back the current transaction, create or roll
back to a savepoint, or alter the session or the system. DDL
statements implicitly commit the current transaction, so a user-
defined function cannot execute any DDL statements.
c) Write to the database, if the function is being called from a
SELECT statement. However, a function called from a subquery in
a DML statement can write to the database.
d) Write to the same table that is being modified by the
statement from which the function is called, if the function is
called from a DML statement.
Except for the restriction on OUT and IN OUT parameters, Oracle
enforces these restrictions not only for the function called
directly from the SQL statement, but also for any functions that
function calls, and on any functions called from the SQL
statements executed by that function or any function it calls.

Call a function in the shell SWF from a imported SWF

We have flash set up as a shell to take lesson data from XML
and display it frame by frame.
We import SWF files when the XML tells it to to be displayed
on the frame.
How can I get the imported SWF file to call a function in the
shell....
basically have a button or movie clip in the imported swf
call the "gotoNextFrame()" function in the shell.

We found a "bit" easier way if anyone is interested.. we have
the have an eventlistner added to the loader to assign a event to
the swf file thats imported:
flashLoader.contentLoaderInfo.addEventListener(Event.COMPLETE,
addEventHandlers);
then when its completed, it adds event listeners and calls
our "goNextFrame" function (then clears it when its removed from
the stage):
function addEventHandlers(event:Event):void
var swfMC:MovieClip = event.target.content as MovieClip;
swfMC.addEventListener("NextFrame", goNextFrame);
swfMC.addEventListener("PreviousFrame", goPrevFrame);
swfMC.addEventListener(Event.REMOVED_FROM_STAGE,
clearEventListeners);
Then in the swf file thats to be imported, its real simple:
next_btn.addEventListener(MouseEvent.CLICK, MoveToNextFrame);
prev_btn.addEventListener(MouseEvent.CLICK,
MoveToPreviousFrame);
function MoveToNextFrame(e:MouseEvent):void
dispatchEvent(new Event("NextFrame"));
function MoveToPreviousFrame(e:MouseEvent):void
dispatchEvent(new Event("PreviousFrame"));

Call Java functions in a C DLL

Hi,
I am develop a dynamic link library in C on AIX that will internally call java functions using JNI. This libaray will be finally used by other C Executable.
There is only one function in C code i.e. Connect. This function internally use JNI and call java functions. Now while compiling I am facing problems. I think that there is some problem with my makefile.
The make file is given hereunder:
JAVA_HOME = /usr/java14
JAVA_INC = $(JAVA_HOME)/include
CC = cc
LD = cc
# Flags to create a dynamic library.
DYNLINKFLAGS = -G -ostdlib -bnoentry -bM:SRE -brtl -bE:Interface.exp
# files removal
RM = rm -f
#------------------------------------- Libs -----------------------------------#
JAVALIBS      = -L$(JAVA_HOME)/jre/bin/classic/
LIBS            = -ljvm -lpthread -lxnet -lnsl -lm -ldl
#-------------------------------- Dependency rules---------------------------#
# shared library files
LIB_FILES = Interface.a
#-------------------------------------OBJs-------------------------------------#
# shared libraries object files
LIB_OBJS    = Interface.o
all: $(LIB_FILES)
# create our librarys
Interface.a: Interface.o
     $(LD) $(DYNLINKFLAGS) $(JAVALIBS) $(LIBS) $(LIB_OBJS) -o $@
# compile C source files into object files.
%.o: %.c
     $(CC) $(DYNLINKFLAGS) -L$(JAVA_INC) -c $<
# clean everything
clean:
     $(RM) $(LIB_OBJS) $(LIB_FILES)
# clean the library's object files only
cleanlibobjs:
     $(RM) $(LIB_OBJS)Now the problem is that the size of the Interface.a file is very small only 552 bytes. whereas the size of Interface.o file is 34428. Which clearly indicates that the problem is with the Interface.a file i.e during linking.
Can any body help me to figure out the problem.
Regards,
Ahmad Jalil Qarshi

I guess, you are better off to ask this question in a C forum. This is a Java forum, you know.

Calling a function in the main movie from a loaded swf

I realize this is probably a very basic question, but I have
loaded a SWF file into another movie. I now want to call a function
in the main SWF. Is there a way to do that? Alternatively, I have a
custom class where I could put the function, but I haven't been
able to figure out how to call it from the loaded SWF either. Do I
somehow need to associate the class with the main movie,
or...?

Never mind - I was doing something very stupid and wasn't
calling the function as a method of a movie clip. I was simply
calling checkTarget(event) rather than
event.currentTarget.checkTarget(event); which seems to work.

I am attempting to have cells use data from a selective month from the year before so that I can show actual from the prio. years each month.

I am attempting to have cells use data from a selective month from the year before so that I can show actual from the prio. year each month. I need to create a spreedsheet using the the Acutlas from the year-to-date and from last year-to-date, but need to report each month.

Hi Tony,
Answering your question would be easier given a screen shot of the source table and one of what you want the summary table to look like.
Is the data you want for each month in a single cell o the source table, or does the summary table need to collect February's data (for example) from several cells and do some math with those numbers before presenting them on the summary table?
