Can someone tell me how to invoke secondary communications with the AD50 CODEC on the C5402 DSK (in assembly) ? From the AD50 data sheet, secondary communications can be invoked by writing D0=1 (software secondary request)to DIN, or setting FC=1 (Hardware Secondary communicati

Hi, I am currently trying to implement a band pass filter to filter out specific frequencies from input data from the microphone. I have visited the sample in the codec.c program ( in TMS3205402 kit). The code to get the data from the microphone is

Hi All, I am interested in writing a MPEG SP decoder for the c54x . I am *fresh* to codec development / Code Composer , though i have close to 9 years in C / Linux kernel/ Device driver programming. I have been finding it very difficult to gather info on what i need to do. I would appreciate it if anyone could point me to resources related to: 1.c54x programming 2. MPEG SP Decoder Mater...

I am doing G.728 Annex G. CODEC. Our coder can pass all test serials correctly. But my decoder can pass the test serials in DISK4, which is for step by step test. When I test my decoder using the 'cw1.bin' in DISK1, many problem was presented. cw1.bin is used when post-fi

Hi everyone, I am working on DSK5416 and CCS. I'm doing real-time using DMA and McBSP to communicate with the codec. I'm working with 16 bits words and with DSP/BIOS configuration. I would like to know if the problem that I have is coming from data alignment. After interruption (full buffer: 1024 words of 16 bits) I use the following function: Interrupt function(){ int i=0,maxisync,maxica...

-Jeff "On C54xx devices, SPCR1[0] access requires a sub-address setting; i.e. SPCR1 register, port 0 (McBSP0). Therefore you have to set SPSA0 first (located at address 0x0038). Are you doing that before trying to read RRDY?" I open the McBsp0 using DSP/Bios Configuration. So I'm wondering, Is the SPSA0 set automatically when using DSP/Bios Configuration ?

hi all, thanks for the support given so far to me, At present i am doing a project on DSK5416, project is to implement LPC coder on DSK 5416. DSK5416 consists PCM3002E codec, this is interfaced through CPLD on board. This CPLD is interfaced in I/O space of the 5416 DSP chip. my doubt is accessing this I/O space in high level language. i have attache a screen shot which spectrum fellow h...

Dear all In 5416 DSP processor : I used MSBSP number 0 and 1 to get CODEC sound data by using DMA channel 4 and 5. Both DMAs are used to get data from mcbsp ports. Frame sync and clock signals are input to this DSP processor. But I have reset problem. When I reset the board I find that sometimes input data is correct and has no problem but some other times input data is not correct. and s...

Is it possible to trigger 2 DMA's off the same McBSP event? Eg. McBSP codec receive event triggers a receive DMA which reads data from that McBSP. Same receive event triggers a different DMA that writes to a different McBSP's transmit register. Can this be done? Thanks, Brian -- ----------------

Hi All, I am doing porting work of AMR Speech Codec(NB) on TMS320C5416. When I use extended memory, I found that fread(File Read Function) and fwrite(File Write) are not working. When I am not using extended memory option, I am able to read and write using fread and fwrite respectively. I have tried with probe points, it is working. Can any body tell how to read and write a file using...
