F28335 DSP/BIOS

Other Parts Discussed in Thread: TMS320F28335

Hai,

            I am using TMS320F28335 with CCSv5.

            I can explain about my Project. 

    ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 

     1. I have to read ADC values and need to apply Filter.

     2. Some other calculations , like finding power and phase shifting  of voltage and  current. 

     3. Getting an output signal from this calculations, this signal and one reference signal is passed through PID and creating one error signal,

     4. Again this error signal and  reference signal is passed through, other PID this error signal need to be take out through DAC using SPI.

    ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- 

            Normally I done this program. but i didn't get the exact sine wave, i guess this is  because of delay in calculations and 2 pids.

            I have to get the exact sine wave in real time with out any delay. For this should i have to do DSP/BIOS?

            I am new to TI-RTOS.

            I checked  example code from "SPA958I". I got how to read ADC values using HWI and SWI.

            But after that how to write other tasks and threads ?

            How the logic works?

            

          Thanks in Advance

  • Hi Akhil,

    You can have a look at the DSP/BIOS User's Guide:

    If possible, I would recommend using SYS/BIOS instead of DSP/BIOS.  DSP/BIOS is an older product and no new development is being done for it.  SYS/BIOS is the newer version.  The APIs are different, so if you're starting from scratch, you should use SYS/BIOS.  You would need to upgrade to CCS v6, though.

    Here is the SYS/BIOS User's Guide:

    Best regards,
