Hey,

I am facing the same problem, I would like to do some trigonometric calculations with the M3 core and I would like to use a fixed-point library. Did you find a solution to your problem?

Best regards,

Sorry, I am missing the context of this question. The IQmath library is for the C28x core.

I am aware that the IQmath library is for the C28 core. I would like to perform some fast sine and cosine calculations on the M3 core and I was wondering if there is any library that operates with fixed point. I've seen in other posts that they recommend using the CMSIS fixed point library for the ARM M3 but I haven't been able to use it with this microcontroller. I would like to know if you have ever tried something similar.

Best regards,

Tomàs

Tomàs,

I have asked a colleague with expertise in this area to comment. I have not tried the CMSIS on M3, other than to expect that it should work. I don't know enough to speculate what might be wrong.

Thanks,

Sira

Tomàs,

My colleague confirms that we have not developed any math operations for the M3.

Thanks,

Sira

OK, thanks for your help with this issue. I've been working with the CMSIS library but I can't manage to make it work with the M3. I'll keep trying.

Best regards,

Tomàs
