Is there any detail document about that? The first thing is to look in TI's Assembly Language Tools User's Guide doc for whatever chip is being used. In your case (C54x), look in this doc: htt

I'm attempting to set up McBSP using code composer v3.1 with a C5416, and can't even get the simple setup from the dma4.c or mcbsp.c to work. I created the configurations I wanted, and used the code provided in dma4.c as a template to open the mcbsp channel and start everything, and the code always stops at this line. while(!(MCBSP_xrdy(myhMcbsp))){ ; } I'm not sure why the xrdy s...

Hi all, I recently experimented with the PEP5416 module, and found the DSP chip to be too slow in processing the code to meet the audio real-time deadline. The idea of my project is to take an audio input via the microphone port of the device and distort the signal to generate a new audio output through the headphones. I was wondering if anyone knew of another portable module that can be us...

Hello, I´m doing a migration from 5410A to 5416 and I´m having problems when returning from interrupt service rutines. I don´t build the project with the -mf option (i´m using near calls as default) because there are several vocoder funtions that we don´t want to change so I want to keep them in the same page and call them as near. For the rest of the program that is in another memory ...


Code not running fast enough

Hi all, I recently found that adding my code to a simple example where the audio input is looped back to the headphones changes the output, which I suspect is caused by the fact that the code I use takes too long to run. One reason this may be caused is the fact that I run multiple filters, which are all implemented using floating data types. Before attempting a fixed point implementation how...

I recently got all of my code to work properly and display normal behavior in the watch window, so I'm beginning to listen to the output of the program. As I expected would probably happen, the output is not correct. To run simple testing, I place the following lines at the beginning of my program for(i = 0; i < dwNumNewSamples; i++){ while (!PEP5416_AIC23_read16(hCodec, &buffer[i]));

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...

I am using the PEP5416 with code composer v3.1, and am having problems with memory allocation. In my code, I use the malloc() command multiple times, though after awhile, the program starts to return null pointers, indicating that I cannot allocate any more memory. The problem I'm having is that I have no idea where this memory is being allocated. I've been making changes using DSP/BIOS and...
