How to use the Motor Control Libraries?

[Alberto_g]

I'm trying to use CW 10.5 and CM0MCLUG.

When calling whatever function, ex.  GFLIB_Sin_F32,

PE_DEBUGHALT() is reached.

The following code is executed, it does not look like a proper sin function.

00000000:   movs r0,r0

00000002:   movs r0,#0

00000004:   lsrs r5,r0,#1

00000006:   movs r0,r0

00000008:   lsrs r1,r0,#32

0000000a:   movs r0,r0

0000000c:   lsrs r1,r0,#32

0000000e:   movs r0,r0

00000010:   lsrs r1,r0,#32

00000012:   movs r0,r0

00000014:   lsrs r1,r0,#32

00000016:   movs r0,r0

00000018:   lsrs r1,r0,#32

0000001a:   movs r0,r0

0000001c:   movs r0,r0

0000001e:   movs r0,r0

...

What's going on?

Does an example of motor control code for CW exist?

If I understood correctly the motor control application notes are all for IAR.

Better stick with 56F for these kind of things?

Hi, Alberto

Would you please help to tell me which type motor do you want to control? PMSM or BLDC? We might have a better solution for your reference.

Sorry, I forgot to mention we are interested in sensored PMSM. Position feedback will be by resolver.

Hi, Alberto

You can find some reference design from this link http://www.freescale.com/webapp/sps/site/application.jsp?code=APLPMSYNCMO&fasp=1&tab=Design_Tools_Ta...

They are use our popular product Kinetis series.

Hope my reply can help you. Any question, please contact to me easily.

Best Regards

All of these reference designs are for IAR. Am I right?

The Motor Control Libraries should work with CW and GCC, but behaves as above for me.

Am I doing something wrong?
