Hi I am working in a group on the project(audio spectrum analayzer). We are using TMS320C5402 DSK. Our problem is that even without running any program (like audio.c or volume.c) we have always output on the speakers that comes from CD player connected to the microphone.

Hi. Just like to check the status of visual linker. Bought the C5402 DSK in January and there are still bugs with it. Had much more control with the memory mapping using legacy linker then. Is there any improvement since then? Are the new users for the latest DSK using v

I am having trouble switching the C5402 DSK to mircocomputer mode using DSP/BIOS. The way I did it was by changing the MP/#MC bit of PMST register value within the DSP/BIOS cdb file. However, my program does not run correctly afterward. It ran okay before when I used microprocessor m

Hi friends, i'm implementing an IIR filter (direct form I) on c5402. The reverse coefficient a0 = 1.000 and some other coefficients are greater than 1. How do I scale these so that I can convert them to fixed-point? Help will be greatly appreciated. Marlo

Hi, I am trying to integrate some Sigmatel AC97 codecs to a 5402. TI have published an application note on this precise combination (SPRA777) but it seems to be both incomplete (references to undefined labels etc) and with more than a few syntax errors. I wonder if anyone has

Pegasus Byron- Please check the c54x group archives. Some time ago I posted asm source to the group that shows how to intialize the codec device on the DSK C5402 board directly, without calling CCS functions. That should give you some guidance in working with the A

Got my interrupts going. I can now read data from the AD50 every time a receiver interrupt occurs. As Dave Helsley suggested, the problem I had was that the DRR register was being overrun because I was not reading it quick enough. If DRR has not been since the last RBR to DRR copy, a

I'm trying to implement a CTCSS tone detector in a C5402. I've tried to implement a Goertzel Filter based on the DTMF decoder chapter in the Analog Devices DSP Applications book. I'm not sure if this is the right approach or not, and it doesn't seem to be working :< Does an

I have some troubles bootloading from serial port. My problem is quite complex : I have a C5402 DSP linked to an ARM7 core based chip through McBSP0 (SPI). I have to bootload code onto the DSP using the ARM because my DSP have no access to flash memory. The ARM is configured as a mas

Hi, I programmed the flash on the C5402 DSK with Flashburn. When I look at the memory in Flashburn it looks like everything burned ok. When I look at the memory in CCS it has all 0xFFFF's. Any ideas why I can't see it properly in CCS? I set the CNTL2 bit to the flash and I've s

Hi friends, I program the c5402 in C language. I see in the codec example that the sampling rates i can configure the codec are only 2kHZ-16kHz using the available function. How can I make the codec to sample at 500 Hz? Is there some other C-callable function which I
