RDK VALUE SB

Other Parts Discussed in Thread: PCM3070

I am referring to RDK VALUE SB in my soundbar design. I have some doubts in software part. 

         We are loading the script generated from pure path into EEPROM on the board. At start up all the data from EEPROM is loaded into PCM3070. But srs wow and equilizer are activated only when the buttons are pressed. srs wow is there in the script loaded and it was already loaded into codec, but becoming active only when button is pressed. WHY?

what is happening at power up? is all the data from EEPROM is loaded in pcm or only a part of it is added. then is the remaining registers are writing at run time when button is pressed.

Please explain me clearly what MSP is doing at run time to Registers of CODEC?

Also i want to implement some extra features like head phone out, 3D effect e.t.c .How can I incorporate them in the existing system.

Please do the needful.

Thanking You

    Hi Srinivas,

    Section 8.1 in the user's guide describes the process flow of the RDK Value SB. The MSP430 host is reading the PCM3070 firmware from the EEPROM and setting the appropriate registers.

    Have you tried directly loading your process flow from PPS into the PCM3070 CODEC? Do you have any issues then?

    I assume you have followed section 10.2 step by step for programming. For part #5 step D, the MSP430 button code can be modified for your situation and the registers for the different functions can be found in PPS.

    Currently on the RDK Value Soundbar, there is already a headphone jack out, so that should be very easy to implement. Other miniDSP effects can be incorporated by following section 10 in the user's guide.

    Also, were you able to find a remote that worked (regarding your last issue)?

    Regards,

    ~John

    Hi John,

    as you said I followed the same guidelines only. But my doubt is that SRS WOW HD is already there in PPS and written to EEPROM, i.e after power up by default it should get activated. it is not doing so. when I press the button it is writing to Registers. 

    Also with the code given with RDK VALUE SB my headphone is not working.

    Coming to RC-5, the code given with RDK VALUE SB is not working with my remote because of some synchronization issues. I have separately written a code for RC-5 on Launch pad and it is working on it. Now i am trying to include that code here. Still it is not working. It is not detecting IR interrupt here. but on launchpad it is detecting and working. I am using timer and port1 interrupts. Please provide any help here.

    Thanking you.

    Hi Srinivas,

    As I mentioned previously, you will have to modify the code in MSP430 in what the buttons do and the commands sent to the PCM3070 relative to that. If you try to program the PCM3070 directly with SRS WOW, are there any issues?

    The code given for the RDK Value SB has those outputs as a sub-woofer out. This can be modified for HP output.

    When you say the MSP430 is not detecting interrupt, do you mean that the device sees the interrupt on the line and isn't responding? or that the interrupt from the IR receiver is not occuring? Have you tried using another remote with the original code?

    Regards,
