Send series of SPI commands from DAQ

I have created my SPI waveforms and then split them up and sent them to 5 different lines on my DAQmx (I have two CS lines).
The slaves here are two PGAs and the MOSI line is setting the gain to one of 11 programmable gains; I have a Ring (drop-down menu) set up for the user to select the gain which is fed in to the MOSI data port on the SPI swap VI. My problem: I need to send initial commands to the slave to configure a pin on the slave (PGA), before I use the Ring to select the gain. How can I send initial commands on the MOSI line to "set" the slave, and then use my Ring to select/change the gain? How can I send a series of commands via SPI before the user selects the command to send to MOSI?
I am using the DAQ 6356 which has no way to recognize SPI protocol so I used SDW to generate my waveforms.

Please refer to this forum thread.

Send ASCII String as Command to Modbus Ethernet Device

Hello Precious Developers,
How do we send the following string command from a PC to a Modbus Ethernet device at starting address 411000 using LVDSC:
"<ID 0><CLR><WIN 0 0 287 31><POS 0 0><LJ><BL N><CS 2><RED><T>H</T>""$0D""$0A"
(Function code 16 - Write multiple Holding registers)
Any pointers / suggestions / example code shall be deeply appreciated.
Solved!
Go to Solution.

hi,
I implemented your solution but when there is an odd number of character, the last character is not included in the u16 array. Is my implemented correct?

Run multiple unix commands from ODI procedure

I want to run a series of unix commands from ODI procedure. I dont want to use Unix shell scripts. (I know that works).I am just trying to place the contents of the shell scripts in ODI procedure with Operating system as technology. But I am unable to execute the proecedure.
For example below is a very small 3 line commands I would execute
filename="/var/test.txt"
ls -l $filename > /var/anotherfile.txt
chmod 777 $filename
I am not sure if there is any specific syntax that I have to follow for executing unix commands. Also I dont want to write a Jython and use os.system command as well.
Appreciate any help on this

First your original question... You can put more than one DOS command on a single line, simply separate each command with an ampersand (&). For example:
mkdir c:\abc & cd abc & dir*
Regarding your concerns about performance, well that would depend on exactly what you mean. Using CLIENT_HOST (or HOST on the server) simply opens a shell (DOS in this case) then passes your command to it. The performance of performing this action really isn't measurable. Basically you are just pressing a button and you should get a near immediate action. As for the performance of executing each command, that has nothing to do with Forms. Once the command is passed to the shell, the rest is a function of the shell and whatever command you passed.
Having said that, if you were to write something sloppy like a loop (in pl/sql) which called CLIENT_HOST lots of times repeatedly, then yes there would be a performance problem because the pushing of the button will cause an exchange to and from the server and each cycle in the loop will do the same.
So the answer to how performance is impacted will depend on what exactly you need to accomplish. If it is a single call to CLIENT_HOST, this should be fine.

My HP Color Laserjet CP1215 only prints when sending a command from a distant computer (shared pr.)

My HP Color Laserjet CP1215 won't print when I send a print command from the computer to which the printer is connected to. The printer is shared. When my colleague sends a print command from another computer, the printer does his job.

I am currently in the same boat. I love how you posted this legitimate issue 3 years ago and there is still no resolution. It really reflects on the company's character and attitude toward their customers.
Hopefully this will get a response.

How to send a command from a vc++.exe to LABVIEW.exe in order to control the button on the LABVIEW.exe

Hello, everyone. Using VC++, I have gotten the handle of a *.exe(built by Labview), but I cannot get the button handle. I want to get the button handle and post the message to control the button. How can I do that? When I use the SPY++, the *.exe(built by Labview) have not any child windows which is very different from the *.exe(built by VC++). In SPY++, what is the LVDChild class? How can I send the message to control the button on *.exe(built by Labview)???
That is to send a command from a vc++.exe to LABVIEW.exe in order to control the button on the LABVIEW.exe. How can I get it ?
Thank you!

Checkout the LabVIEW ActiveX server interface in the User Manual in Chapter 20, Windows Connectivity and the VI Server Reference in Chapter 17, Programmatically Controlling VIs.
There is a sample for Visual Basic under examples/comm/VBtoLV.frm, which should be quite simple to translate to Visual C as long as you can figure out the basics of ActiveX programming in VC (I have never done anything with ActiveX in VC). For those basics I would recommend some text book or MSDN.

Pls help in sending multiple resposes after analysing the sequential commands from the device

Hi all
pls help me in sending sequential responses for the different commands. For example,i have to send the response1 for command1 then again host wll send the some other command ,say command 2 after receiving response 1,then again i have to respond to the corresponding command.i m using the pci-6221 card not tradition DAQcard.
regards,
nitin

Hello nitin,
It sounds like you are looking for some examples on how to program your
6221 DAQ board. I highly reccomend taking a look at the LabVIEW
shipping examples that install with the DAQ driver. To access
them, open the NI Example Finder by going to the menu bar of a VI and
selecting Help >> Find Examples...
If you have any specific questions, please feel free to ask!

Sending sysex commands from MainStage

Has anyone figured out a way to send sysex sequences from MainStage when changing patches? I need to use sysex to switch one of my keyboards between its "Program" and its "Combi" mode and I don't see anything obvious in MS 2 to do this.
I suppose it will be necessary to use an external utility like MidiPipe or Bidule or Max to listen for special MIDI commands from MainStage and then generate sysex messages but I thought I'd check first to see if anyone has an easier method.

AFAIK - there is no way to send sysex from MainStage 2. Maybe Applescript can do it? MainStage can execute Applescripts.

Sending down Linux commands from database

Hello
Im working with Oracle 10.2.0.4.3 on Linux SuSE FUSE Version 2.3.0-RC0-SL0/SLES-9.
Im currently doing an extract of BLOB files down to a directory on the server.
When I do the extract the Oracle user becomes the owner of the files and my own user doesn't have the access (neither read or write) to the files.
I cannot receive Oracle access due a security issue so Im wondering if its possible to send down a command from the database that does a
$chmod a+rw my_directory/*.* ?
Iv looked into the some forums and I didnt find anything in particulate that would help me, so Im wondering if any of you know if this is possible ?
BR / SA

Hello
Thank you for your advice but the question was to send down Linux commands from the DB, not do anything in the Linux enviroment.
Here is a good place to start that I found on the net.
public class JShellCommand {
public static int execute(String cmd) {
try
String[] shellCmd = { "/bin/sh", "-c", cmd };
Process process = Runtime.getRuntime().exec(shellCmd);
int exitVal = process.waitFor();
return (exitVal);
catch (Exception e)
return 1;
load it into db with loadjava and wrap it with:
CREATE OR REPLACE
FUNCTION Shell_Command(
p_CMD IN VARCHAR2
RETURN NUMBER
AS
LANGUAGE JAVA
NAME 'JShellCommand.execute(java.lang.String) return int';
For OS command you can use:
public class JCommand {
public static int execute(String cmd) {
try
Process process = Runtime.getRuntime().exec(cmd);
int exitVal = process.waitFor();
return (exitVal);
catch (Exception e)
return 1;
and

How to run multiple DOS commands from a single Webutil Client_Host session?

Hello all,
I have a requirement where I need to create an interface with SVN from Forms for basic checkin-checkout of files.
So, I've been trying to use webutil client_host to open a command line session and issue svn commands.
For svn, sometimes I need to give multiple commands like change to a particular directory and then run an svn command.
But client_host takes in only one command at a time and I'm unable to issue a series of DOS commands to perform
a particular task.
Is there a way to do this?
Pls suggest.
Regards,
Sam

Also HOST command in forms will execute the OS coomand from the clinet. Is there any way to execute the OS command on the server from the forms clinet?

[SOLVED] Alpine - Error sending: No default posting command

Hi, I have installed the Alpine mail client yesterday, and it all works nicely, except I can't send mail. Everytime I try I get this message:
Error sending: No default posting command
I have tried googling around, and from what I understand Alpine uses sendmail by default, but I haven't got it installed, nor I can find it in the repos. Is there any way I can change this? And what can I use to send mail?
Thanks.
Last edited by finferflu (2007-12-26 16:02:13)

I haven't dug it enough yet, and I'm not sure that this is possible, even though Alpine is very customisable as far as I can see.
I'll let you know if I find anything
