Hi,

I have some problems with the project that I have in CCS. Could you help me to fix that?

Best wishes,

It seems like you are using Iq library in your project and you are missing its header files.

Check #include<IQmathLib.h> in header files

and go to project properties and include option & add IQmathLib directorry in search path.

for more details

Thank you so much!

I have another question. I would appreciate it if you answer that too. How can I solve this error ?

Hi Milad,

Can you confirm what software example within controlSUITE you are leveraging. Please note that the C2000Ware is our latest SDK that has our most up-to-date device and library support. Do also note that the IQmath is not actively leveraged in recent examples with the move to FPU32. Is there a specific reason to still leverage this library?

Regards,

Ozino

I fixed the previous error. I am using IQmathCPP.h and have these errors.

Is FPU32 a library like IQmath? How can I get that and use it?

0 Ozino Odharo over 2 years ago in reply to Milad Bahrami Fard

TI__Mastermind 21305 points

Yes, FPU32 is a library. You can find the support in C2000Ware under the the libraries-> math -> FPUfastRTS. There are examples and documentation available in that document.

Here is a sticky post comparing FPU vs IQmath. Note FPU is generally easier to code

If sticking with IQmath, please see the examples and documentation provided in C2000Ware to understand how to properly include this library support in your project. The errors shown appear to be related inclusion errors.

Thank you so much for your response. Sorry for asking again. I included the libraries IQmathLib.h and IQmathCPP.h as examples C2000Ware but also have the errors for IQmathCPP. I checked mine with the 2838_IQsampleCpp example in C2000Ware. Every thing is the same but I have these errors.

Can you check the project properties and ensure that the Compiler "Include Options" and Linker "File Search Paths" are similar for the IQmath lib.

0 Milad Bahrami Fard over 2 years ago in reply to Ozino Odharo

Prodigy 10 points

Thank you for your response. I did everything similar for the IQmath lib. Here are the Compiler "Include Options" and Linker "File Search Paths. I don't know why these errors pop up.

Milad,

So there are a couple of issues occurring here:

You have references to controlSUITE and C2000Ware. These packages both provided device support for C2000 where C2000Ware is the latest and controlSUITE is outdated. Please remove/update references to controlSUITE and update to C2000Ware
Since this is a F2838x project, I recommend you copy, import and reference the 2838x IQ math example (2838x_IQsampleC) located at: C:\ti\c2000\C2000Ware_DigitalPower_SDK_4_04_00_00\c2000ware\libraries\math\IQmath\c28\examples\C\2838x Please leverage this example in your development
1. you can either migrate your application code to the example and continue from there
2. OR reference the project settings and update IQmath references accordingly
Looks like your main_isr file does not include the #include "IQmathLib.h"

Once you complete these changes, you should have a project that compiles and is ready to test. Please demonstrate that you've addressed these steps.

Regards,

Ozino
