Other Parts Discussed in Thread: CONTROLSUITE, C2000WARE

Tool/software: Code Composer Studio

Hi,

Can anyone describe in brief how to change the program (for the link given below) as i was not understanding where to change in the program. Otherwise anyone could suggest any material so that it could be helpful in solving the problem.

Hi,

Is there a specific example program from C2000ware/ControlSuite you're currently investigating?

Some material that may be helpful to you, but is not F2802x specific, is this Application Report, http://www.ti.com/lit/sprac94.

The DAC mode example utilizes a sine look-up table and explains the methodology of stepping through it to generate a specific sine wave frequency. It might be helpful in explaining some other concepts depending on what you're trying to accomplish as well.

Best,
Kevin

Another option is to use the Signal Generator (SGEN) library within C2000ware:

C:\ti\c2000\C2000Ware_1_00_05_00\libraries\dsp\SGEN\c28

It may be applicable with it being fixed-point.

Best,
Kevin
