Part Number: TMS320F28069
Other Parts Discussed in Thread: C2000WARE, MOTORWARE
I use the dual motor routine lab12c, the fixed-point library used in this routine, I would like to ask how to convert it to a floating-point library and enable the F28069 FPU to speed up the calculation speed? I tried to set rts2800_ml.lib to rts2800_fpu32.lib, but the project reported an error, how can I solve it?
You'll also need to replace a few of the libraries, as shown in this picture. The spinTac and romsymbols fpu library versions are available in the same folders as the existing versions. The iqmath fpu version can be obtained from C2000Ware (path pasted below). Note that one is an index library and the other is the actual library pointed to. Once I made these changes, it builds without error.

I built the lab12c project located at C:\ti\motorware\motorware_1_01_00_18\sw\solutions\instaspin_motion\boards\boostxldrv8301_revB\f28x\f2806xM\projects\ccs\proj_lab12c
I enabled FPU32 in processor options, replaced the RTS lib with rts2800_fpu32.
Then excluded the existing ROM, IQMath, and SpinTAC libraries, and replaced them with the FPU32 versions present at:
C:\ti\motorware\motorware_1_01_00_18\sw\modules\fast\lib\32b\f28x\f2806x
C:\ti\motorware\motorware_1_01_00_18\sw\modules\iqmath\lib\f28x\float
C:\ti\motorware\motorware_1_01_00_18\sw\modules\spintac\lib\32b
See the picture, the project built without errors.
