USB HID example compilation issues with IAR

Hi,

I have downloaded UM0424 and opened the SWARM workspace in IAR workbench v6. The project compiles with lots of error, all of which are like this:

declaration is incompatible with ... then it lists a data type in core_cm3.h that is incompatible with the definition in intrinsics.h (the IAR ARM inline function file).

Has anyone else seen this problem?

Thanks, Charlie

Replying to my own post in case anyone else needs the answer...

The older versions of CMSIS are not compatible with the later IAR versions. The CMSIS stuff has to be updated to work with IAR v6.

Did you get this to work completely?  I have the same problem.  I have the latest, 6.30.3.3241 EWARM and common components version 6.3.12.2118.

I was able to get the STM3210B-EVAL software (UM0435) working using the techniques to change CMSIS, but not the custom hid project in the USB-FS-Device development kit (UM0424).

1. Check the box against ''Use CMSIS''  at the following

Project-->Option --> General Options --> Library Configuration --> CMSIS

2. Remove 

$PROJ_DIR$\..\..\..\Libraries\CMSIS\Core\CM3   from

Project-->Option --> C/C++ Compiler --> Preprocessor

3. Select the correct target controller.

1- Support of ST-LINK/V2:

You need  to run  ST-ink_V2_USBdriver.exe from [IAR_install directory]\Embedded Workbench 6.\arm\drivers\ST-Link

2- The compiler adds a lot of new intrinsics which  breaks other CMSIS headers since there will be double definitions.

To overcome this change, it's mandatory to :

  - Check ''Use CMSIS'' option from: Project options > General Options > Library Configuration

  -  Remove all CMSIS headers files from your project.

For ST packages you should remove:

$PROJ_DIR$\..\..\..\Libraries\CMSIS\CM3\CoreSupport  from  [Project>Options>C/C++ Compiler>Preprocessor]

Hi Aaron Clarke,

To get the compilation running I used the version of CMSIS that was provided with IAR. To achieve this I did exactly how pila.rosarium.001 has stated.

I was trying to use the example on an IAR dev board rather than an ST one. This mean I had to go through the example code and remove all the dev board specific stuff - which was a lot. I found the example was well written for all the various ST dev boards, but hard work to port to different hardware.

I am using the STM3210B-EVAL, I was able to get it to work finally.

Thanks for your help.

Thanks for responding to my question.  I was able to get it to work after I read your original posts.  I was more work than I thought at first.

I also have to port it to a different board so I will have to remove the eval specific code like you did.  I expected that would take some time, but I never anticipated the IAR problems.

Best regards,

Aaron

, it should also work for the other USB FS device demo projects, I tested out the joystick mouse too.
