labview for stm32f103 development board?

mat2_chan2 — Fri, 13 Nov 2009 16:09:28 GMT

hi,

good evening, i'm a student who's currently working on a thesis that involves the stm32f103 development board. our board uses a 32-Bit ARM Cortex-M3 Processor with a 128KB flash memory. it also has RS232 and USB ports for direct connection to the computer. i was just wondering if there are any labview products that are compatible with our board?

Hi mat2_chan2,

You have a few options depending on what you mean by "compatible with our board." There are 2 options I see:

1) You can use LabVIEW to communicate with your evaluation board (through RS232 or USB). If you've already got your code working as you wish on the evaluation board, this would be the option for you.

2) You can use LabVIEW and the LabVIEW for ARM module to download actual LabVIEW code to the board itself. I tried to identify whether or not your chipset would be supported, but you didn't specify enough information. You can look here: RL-ARM Real-Time Library. (Chips for which the RL-ARM Real-Time Library exists can support LabVIEW code.) More information can be found at www.ni.com/arm. This method would require background work in order to port LabVIEW to your chip - integrating all of the chip's functionality into the LabVIEW environment. (If you're really tight on time, you need to take this into account.) See this link: Programming Additional ARM Microcontrollers with LabVIEW (without the LabVIEW Microprocessor SDK)

I hope this helps,

good evening,

thank you very much mr. Kevin_S, that really cleared some things for us. we have already ordered the board but still hasn't arrived yet, so we're not very sure about the chip. based from our research, we think it uses the stm32e103RB microcontroller.

we'll be posting again soon and we appreciate your help. thanks.

Where can i get the necessary paths, #defines, and libraries for the TargetConfig.ini file and the template files that are both needed for the target folder for STM32F103RB? By the way, I dont have LabVIEW Microprocessor SDK

Hi Aeolia,

Are you planning on using LabVIEW Microprocessor SDK, or are you using another National Instruments product? Are you going through the port guide? If so, what version? Can you post a link please?

I'm not planning to use LabVIEW Microprocessor SDK. I will only use Labview 8.6 and Labview Embedded Module for ARM Microcontrollers v1.1. I'm currently followng this guide: http://zone.ni.com/devzone/cda/tut/p/id/7152 to create a target folder for STM32F103RB. I'm stuck on the part wherein I will add any necessary paths, #defines, and libraries for any additional drivers for the TargetConfig.ini file and I also don't know where to get the µVision template files of STM32F103RB. Can you please help me? Thanks.

DiscoBall — Wed, 10 Mar 2010 23:41:20 GMT

Thanks for your reply, this clarifies a lot. When you download libraries that define IO pin mappings and register locations you should add the paths to those files into the TargetConfig.ini. That way, when building the compiler and LabVIEW knows where to find the correct header files, etc. It appears that you can get some libraries from ST website for the STM32F103RB. LabVIEW for ARM contains many of the files and defines that you may need, but you may have extra for will need to change so that you have the right mappings.

The template file should be in the folder that you copied. For example, you copied the LPC2378 folder and renamed to STM32F103RB. You would then need to go into that folder and open the Template folder and modify per step 10 of the link you had sent me.

Hello

I'm also trying to port labVIEW on a STM32F103RB. I followed our tutorial on the LCP3180 to create the template folder.

I succeed to debug the errors to build the project.

I succeed to download my code to the flash memory. I do a while loop with an indicator on the index loop and a wait function of 100ms in the loop.

But I have an error on the "Processor Status" : Stopped at 0x08002C9E

This address change if I modify the labVIEW Code.

I join a capture screen of my error.

What is the action which is done during this stage ? Do you have an idea of the cause of this error.

Thanks, best regards.

Howdy,

Is

Let's try a couple of debugging steps:

0. What version of LabVIEW are you using? (Help»About LabVIEW)
1. Can you run non-LabVIEW generated code, like a basic C program that blinks an LED?
2. What optimizations, if any, do you have turned on?
3. Do you have a wait inside your while loop?
4. Can you open Keil and show the call stack window.

5. Did you follow the porting process of the RT Agent?

Hi ARM keiller

Can you please upload here the whole STM32F103RB target folder that you are using so that I can compare mine with yours? You can just make the whole folder a rar file so that uploading will be much easier. Thanks

Thanks for your answer

I saw that my program stopped on a breakpoint due to "semihosting_swi" so I modified my "retarget.c" file. And my program ran !!!

Now I'm trying to include the library of STM32_functions supplied by keil's libraries with LabVIEW. In order to use this function to

configure my GPIO... But I don't succed !!! Because Inline C nodes are not enough powerful to make this.

And when I open uVision in debug mode I notice that my HCLK run at 8Mhz and not 72Mhz.... Is it normal ? I thought that RTX configure

automatically the clock at 72 Mhz ...???

Thanks for your answer.

Hi aeolia

Why do you need to port LabVIEW on a STM32F103 ? Can you specify your application ?

Give me your email address and I will be able to give you my folder.rar .

I'm trying to configure my GPIO, but I haven't yet succedded. I hope that you will be able to help me later.

Best regards.

Hello and you're welcome,

What do you mean that you did not succeed when trying to include the libraries? Did you get an error? Can you describe the process you are going through in more detail please? Perhaps you can help the community out and post what you have so far so that we all can see?

I am unsure about the clock issue, I will look more into that.

Hello DiscoBall

I succedded to use my lybrary of function because I found how the files.c and .lib can be attached to the project when this latter is building.

I identified my problem : when you create a new ARM project with EK-LM3S8962 or MCB2300 or MCB2400 and that you right-click on your target on "new" , you can select "Elemental I/O".

But if you create a project with a Philips NXP LPC2378, LPC2468 or with the luminary micro device and that you click on the name of your target in the Project Explorer on "new" you CAN'T create new "Elemental I/O" because there is NOT "Elemental I/O".

I modified my VI to configure my GPIO and I created my ressources and pins with the "Elemental I/O Device Wizard to create the eio.xml.

But I can't do anything because of the "Elemental I/O" doesn't exist.

Please have you an answer for my problem. Thank you.

Best Regards

Hi,

What path do you have your eio.xml file in? Does the eio.xml specify the correct path to the VIs in the file? Did you change the name from "Other" in the project to the correct device?

Hi ARM keiller

Our ARM microcontroller will basically control the movement of the motors, gather data from the sensors and sends it to the PC wirelessly via zigbee. We already have the labview codes for all of this. We only just need the STM32F103RB target folder.

Here's my email address: beniong@yahoo.com

Thanks

Hi ARM keiller

I knew how to drive GPIO/ADC/LCD and so on in labview ARM module by inline C CODE.Tell me your Email ,I will give it to you .I also ported STM32 in labview , it seems successed , but if I use inline C code in it ,it can not work.so can you send your STM32F103RB target folder to me ,and I send mine to you .

Here's my email address: beniong@163.com

Thanks

Hi !

Thanks for your answer. I succeeded to configure my GPIO.

I'm trying to modify the C source code which manage the different interrupt. I have an error which causes an Hard Fault interrupt .

How would you do to detect the source of this error ???

When I use µvision I can't go step by step because I'm stopped by this line : while(OCDI_RDMStart != 0x01);

And I don't succeed to activate thiscondition from LabVIEW.

And if I use breakpoint on LabVIEW code I have an unknown exception....

If you have a great idea about this thanks to share it with me.

best regards

Hi Arm keller,

Can you post screenshots of your error and post your code. What did you modify?

ARM keiller — Sat, 03 Apr 2010 08:09:57 GMT

For everybody who want to port LabVIEW on a CORTEX M3 and use an interrupt . Please read this :

RTX Library version for Cortex™-M devices allows to select the running mode of all user tasks. User tasks may run in two modes:

Unprivileged - Protected mode or
Privileged - Unprotected mode.

In privileged mode user may access and configure the system and control registers like NVIC interrupt controller etc. This is however not allowed from unprivileged mode. An access to NVIC registers from unprivileged mode will result in Hard Fault.

#define OS_RUNPRIV 1

OS_RUNPRIV enables running of all tasks in Privileged mode. It must be set to 1 to enable it or 0 to disable it. It is disabled by default.
You can enable the privileged mode for old projects. The existing code will run without any modifications when RTX_Config.c configuration file is replaced with a new one and a project is recompiled for a new Cortex™-M RTX Kernel library. Tasks are not protected in privileged mode and you may configure the system for example the interrupts from any task.
Privileged mode is disabled by default. This allows all tasks to run in protected mode. The tasks are not allowed to change system settings, change interrupts etc.
