TMS320F28069F: InstaSPIN-FOC Lab project : Lab11a: floating point support with the fpu32 enabled

Other Parts Discussed in Thread: MOTORWARE

Hello,

I have a question on an InstaSPIN-FOC Lab project in motorware.

Particularly it is on Lab11a.

It seems that lab11a does not use the fpu32 available on the 28069 device; instead it uses the softlib for the floating point support.

However I plan to use the fpu32 for the lab11a.

I have noticed that lab10a uses the softlib for the floating point support, whereas lab10c uses the fpu32 for the floating point support.

Therefore, may I create the lab11c CCS project from the lab11a project in a similar way as the lab10c CCS project is created from the lab10a project?

Thank you for your guidance.

With regards,

JS Yoo

    Yes, you can refer to lab10c to use the fpu32, but I don't think it's necessary to do this for motor control, The IQmath based project should have the same performance as using floating-point.
