ARM module + PWM LM3S8962 problem
Hello.
I'm experimenting with LV2009 + Embedded module for ARM (also the 2009 version).
(1) what actually works, a few screws, I did (no examples):
-loop infinite + led flashing + 200ms wait timer
-infinite loop + number of the current iteration on LCD + 200ms wait timer
(2) the demos provided in
(3) PWM EIO problem: I got the first aforementioned VI (1) (LED light MagNet) and added a HIO PWM5, in the same loop. -What is the wired to the PWM EIO node value mean? Duty cycle 0 to 100? Duty cycle 0 to 1? The number of ticks to the top state PWM? Sometimes it worked, sometimes the PWM was logical high all the time. -If I add a property PWM5 EIO node and try to put anything, it breaks. From what I've seen in the uVision debugger, it gets stuck in the default interrupt handler section. I can't understand how he got there. Please help me with an example of how fully configure a PWM EIO, exercising control over the frequency of having to test cycle, everything. Thanks in advance for your time & help. Paul. Hi Paul,. This looks like a problem where you (or rather the code generated LabVIEW) set up the device before you activate the device PWM. The target will fault in this case, but the Simulator will not. Because that the PWM EIO node initializes and allows the PWM peripheral, if the EIO property node is executed before the EIO node, the target reproach. Try using a sequence structure to make sure that the node of PWM EIO runs before the property node.

Open 'startup.s '. Goto line 193: ; set the system clock to run at 50 MHz LDR R0 = 0X01C002C0 B __main Replace R0, with the right values in "sysctl.h" line 236: in my case the value of the 6 Mhz Crystal which is "0x000002C0". Calendar of PWM is restored and serial port works fine now. I downloaded the FPGA module in a PXI controller, running XP. When I tried to unzip it, the unzip operation fails every time. What is the cause? Is there some sort of requirement for this unpack? Hard disk size requirement? Thanks for help. I discovered what the problem was. I downloaded the FPGA module via the link below. When I tried to unzip it, I would use the default path. Apparently, the default path is a space at the end of his 2nd record, counting from the end of the path. It is a small bug in NOR, but it needs to be fixed. It is difficult to catch, because I don't expect something like that happening.

Adobe Lightroom GPU troubleshooting and FAQ Mike LR5 - no base in the develop module Panel [was: problem upgrade Lightroom 5?] I updgraded to L3 to L5 (Win8 64bits) without no problem, except for the 'Basic' Panel in the develop module. I tried the upgrade to have the 'new' slides here - highlights, shadows... But I still have the old (recovery, light...) there. What has gone wrong? What will I do to get updated? If you change a photo that has been already transformed into Lr3, then you are probably using Version 2010 process, which includes the sliders as recovery and fill light. You can update the PV2012 image in the camera Calibration Panel in the develop Module.

It seems to fail clips HD special Matrox, but only when I play their first. It happens when I click on the first source window and then the timeline and then beginning of jogging or rub in the timeline panel. It is switching between source and first program that triggers the appcrash for sure. While first actually did when you switch from source the program monitor in the app itself? I noticed on my HDMI video monitor when switching as mentioned, the monitor loses the input signal and is to scan the image.

Any help much appreciated. I'm sorry, I didn't notice the Quadro card in your initial post. The version that I gave you was for Geforce cards and the Quadro have a tree of different version. The Quadro version equivalent to the driver I meant 275.89. However, they have a Quadro version that is not yet out on their downloads page standard which has the equivalent properties on the latest Geforce. Download and install after you have uninstalled all the software/driver Quadro you currently have. http://www.nvidia.com/object/Quadro-Tesla-Win7-WinVista-64bit-285.58-WHQL-driver.html Make sure that you choose the custom installation and remove the Nvidia update installation list if it is there. Try and see if that helps. If this isn't the driver to try the 275.89. Eric ADK I have four Wordpress blogs I visit. WordPress has a black bar at the top of the screen that you can click on and it will bring you to the top of the page. I am running FF 38.0.5 and on one of these blogs, this feature no longer works. I ran in safe mode and the device worked properly. When I uninstalled add each on one by one to understand what can be, the problem persists. How is that possible? Hello What I want to do: I need to output a PWM signal with variable frequency cycle and duty using the DAQ assistant for a card with digital output. The max frequency should I * need is about 500 Hz. What is stop me: I can't understand how my cursor frequency relates to a real Hz frequency. What's next: Well, I wish that a simplified approach to exit a pwm signal to a digital output on a camera card or be able to determine the timeing/frequency/delays more. I guessed just to get a wave that looked nice on the graph, but I have no idea on what is the actual frequency. (How can I measure it, so I can guess and check to understand a range I need?) No change to my code attached, or new ideas would be great! I'm still fairly new to labview for details is less appreciated. I hope that it makes what I'm doing. Thank you! GerdW, This seems to be much more accurate. I used the ms timer as my input, so I reduced my input par.001 frequency to compensate for the difference of thousands on my clock. This seems much more accurate. Thank you.

In the past we used Microchip microcontrollers (PIC16 and 18), a simple IDE and a C compiler, but for the new generation of devices we will use microcontrollers from Luminary Micro ARM. Since we are also users of LabVIEW, the choice for the LabVIEW embedded module for ARM seems logical. I read a lot of documentation OR and watched the tutorials, but I'm still uncertain on what we may or may not do with the module. Until we buy eval kits and the module, I need to have some facts. I apologize in advance for the number of questions, it's just that the use of LabVIEW for the development of material is completely new to me Thanks in advance for your help. Paul Hello Paul! I'll try to answer your questions and I hope someone else can add more information if necessary. Answer: no, that would be a level 2 device, we now offer three level 1 devices and information on these can be found on the link you condition. Answer: you need to add yourself as described in the link you provided. Answer: is trickier, LV Module Embedded for ARM in trial mode will have some limitations (size applications, can open the development environment for a number of days and so on), but it should not have limits when it comes to other targets as described in the links that you have already provided. When it comes to the JTAG interface, I would recommend using the Keil ULINK2 USB-JTAG. Answer: I would like to make use of the Keil ULINK2 USB-JTAG Adapter for debugging and allows us to download the code on the target. In fact, it's the only way we can download code on the ARM, but we can use a serial port / TCP in addition to JTAG debugging.
Answer: Yes. Answer: I/O could be implemented using the basic IO layer provide us as described here:

Basic i/o on LM3S8962 stops execution I'm using LabVIEW 2009, boarded the LM3S8962 evaluation board for ARM and ran into problems with inputs and outputs basic predefined for the buttons - without basic IO, everything works fine, but with a button, the execution stops immediately with no error message. A similar code worked perfectly on the original version of Embedded for ARM 1.0 & LabVIEW 8.5. Is no longer, I can test with this version since the period demo has expired. I tested on 2 completely separate hardware games and Embedded for the 2009 ARM installations, with the same issues in both. I have attached 2 samples of simple work & work no screws Stuart Read the button once more - the port is also configured in the EIO node, so first reading detects the port misconfigured. Hope you don't mind for the "enhanced functionality. cRIO, FPGA, portability to different configuration of module e/s Hello people! For my research project, I need support. I have to implement the NO-tutorial: "CompactRIO Control Design and Simulation Tutorial" on different hardware. My cRIO-9004 is no problem and the NI9104 chassis is the same. Occure in problems with the config of the i/O-Modules: Tutorial-config: Slot5 = NI9505, Slot8 = NI9221 MyDevice-config: Slot1 = NIcRIO-9215, Slot2 = NI9263, Slot3 = NI9217, Slot4 = NI9474, Slot5 = NIcRIO-9423 I think that there should be a smart way to port this programm for a different config and change the I/O-link with another module without neckshoot the programm. do not know how, because I am a newbie of LabView. your ff Hi ffelix, The tutorial works with a 9505 (H-Bridge for Servos) movement Module and a Module of the 9221. In your configuration, you HAVE some, a zone of OCCUPATION, an RTD, a DI and a Module, but none Module movement to control a Servo. So if you plan to do a similar Assembly, you must use the AO Module or a Module (PWM) with an external driver circuit to control a motor. And rather than use the software NOR Motion, which I think is used in the tutorial, you will need to program the motor by yourself from scratch part on. Christian Hello I have a Mac Pro 3.1. 16 GB of ram in it, but sometimes only see 14FR. 8 x 2 GB 800 MHz DDR2 FB-DIMM What could be the problem? Sometimes you see all the memory and sometimes not. 2006-2008 (1.1 - 3.1) use FBDIMM that work how and fail over time. When they fail if all goes well, they don't disappear that you encounter. Often, they fail when you access and which can cause a kernel panic. Sometimes the resettlement of the affected module solves the problem, but often this fix is only temporary and the module must be replaced. Impossible to install the modules that are hosted outside of AMO I can't install any add-on that is hosted outside of AMO, in Firefox for Android 40.0.3, nor in Firefox Beta for Android 41. What I think should happen: I have download the file as signed (it records to SD card), then open it with Firefox and Firefox should ask me if I want to install this module. What is really happening: an add-on is downloaded, but when I open it is file as with Firefox - nothing happens. Firefox comes to shows me a blank screen (see the screenshot). My friend has this problem too. Looks like a regression bug (because I could install add-ons hosted out of AMO without any problems in previous versions), but I'm not entirely sure. So my question is: should I file a bug on Bugzilla or is it possible to install the modules hosted outside of AMO to Firefox for Android and it's just me something wrong? My phone has Android v2.3.5. UPDATE: apparently, I can not install the modules of local files, but can do some some sites. My module (I have problem with) is hosted on Github, and I can't install it for whatever reason. Update 2: it seems that modules can be installed from Github if she is not just a file (because Github changed Content-Disposition of at least some types of raw file of 'inline' to 'attachment'), but a binary attachment to a "news release". Apparently, I found a work around for this problem, so that this issue does not require a response more.
