Hello, everyone:

I have a question about rts2800_fpu32.lib and need your help.

To compile the project for floating point, the following steps were done:

1 In Runtime Model Options, under "Specify floating point support (--float_support) pull-down menu: Select "fpu32".

2 In "Include linker file or command file as input (--library, -l)"box, click green plus sign and add rts2800_fpu32.lib(run-time support library).

However, after buliding my project. I got a warning message"function sin declared implicitly". And, the calculation result of Sine function is also wrong.

DSP: f28335 CCS version: 6.0.1

How can I figure it out? PLEASE.

Chengfu,

The warning message is saying that there is no function prototype for sin(). Did you include math.h in your source file?

Regards,

David

I also suspect you failed to include math.h. Is that the case?

Thanks and regards,
